Simple test to try if it implement is accessible. Try operating a function like curl fully and hold joystick in that position and if possible check pump housing temperature vs suction line temperature. If housing gets significantly hotter than suction line indicates pump is leaking internally...

Since neither the FEL nor 3 point is working checking the system relief would be next logical step but a little unusual for relief to fail completely open but anything thing is possible. On your tractor is it a direct hose or steel direct from pressure port on the pump to loader valve or does...

Lifting crooked would point towards potential of one of the lift cylinders leaking internally but that shouldn’t cause any sponginess and would expect that to a constant problem not only when cold.

Long shot but can you check Kubota or Deere models of similar size to what tires are offered. If have same size R1 or R4 and offer R14 would think those sizes would work on a Massey as well.

Off the wall thought but can you check the temperature of the pressure line to the loader valve vs power beyond and tank. If, repeat if there is some type of restriction in the flow path it might aerate the oil over time which would then settle out overnight. Checking for heat rise in those...

That model may have the regenerative dump option which speeds up the dump by 30 - 40%. Soft or spongy normally indicates that air is getting into the system but I would expect this to more of a problem when oil is cold vs hot. Any rubber hoses on the inlet or suction side of the pump? If yes...

Sounds like one of the quick disconnects has come partially undone or is failing in the dump circuit. When these fail they act like a flow restriction. Try unplugging and reconnecting the quick disconnects to see if that possibly solves your problem

Sorry but no I do not know what size the O-rings are.

There is an O-ring in the female half of the coupling that can be replaced to stop external leaks.

I believe you are correct on majority USA assembly and imported version is noted on the website.

Has the dealer checked charge pressure when hydrostatic tranny isn’t working? Does it make any different noises when not working vs normal driving? Not sure what type of control is on that HST but would also want to monitor pilot pressure if it is electronic control or hydraulic pilot control...

Not sure where you are located but there are O-ring kits available online. I suspect that those are metric sizes. Typically sizing is Inside Diameter and cross section (thickness) of O-ring. For regular hydraulic oil nitrile (Buna N) or Viton - FKM are both acceptable compound materials. The...

Yes O-rings are made to specific sizes and there different materials or compounds used for use with various types of fluids. Possible a piece of the old O-ring is holding the valve open. Don’t just randomly start adjusting the relief valve without installing a pressure gauge so that you know...

If like my 2400H it is just sandwiched between a couple of steel washers and has a wave washer for setting tension or friction. On mine hardest part is getting my fat fingers in the area where the washer goes.

Good job on diagnosing the problem(s). I suspect the “blind” cavity has radius on the machined corners and requires the rounded or tapered edge. The OEM may have installed a check valve in the system to prevent running the blades backwards which would explain why it stalled the tractor but is...

How many people are more concerned about the GPS screen or talking on phone vs looking through the windshield? From what I have observed it seems like a growing majority of drivers are.

Does it have markings on the hose like the one behind it that says 9.5 mm?

Is it happening turning both was ways or more prominent in one direction? If you stand on one corner of foot platform does the deck tilt from suspension sag? Agree that seems strange that corner gauge or anti scalp wheels are not adjustable.

If scalping can you have a friend watch what the deck is doing while you turn to see if something is moving in the suspension or deck linkage allowing the deck to shift.

Is that from drive tires skidding during turn or from the deck? Looks like tires in pics but not sure.

Used to be in some states or towns they only had to treat you if unconscious without insurance. Not sure if those rules still apply today or not. Maybe stop giving free medical to prisoners and provide it to people that have earned it working for living.

Is the cost of medical due to actual medical costs or the insane premiums for malpractice insurance. A family member years ago said her malpractice insurance paid by employer was more than her yearly salary. She was a physical therapist so not even in surgery risk category.

On my 2400H there is a switch on the clutch,PTO lever & seat. Not sure about HST pedals since has switch on the clutch which disengages drive to the HST. Agree that it would be nice to know what “won’t hit a lick” means. Starter won’t engage, engine turns over but not try to start, etc.

When lifting a load on 3 point what pressure do you see on gauge you have plumbed into the “P” port of loader valve?

I looked at parts breakdown that I have for Rexroth hydrostatic pump and motor. it showed having two fishtails per side on the port plate for the pump and one per side on the motor. I am not positive Kioti is the same design though.

Richard It has been years since I worked on a motor where the gear case was not a separate item and the two end covers also two separate items so memory is questionable at best.. I recall there was some technique in getting the seals and pressure plate installed into the gear case end cover...

I guess I don’t understand how people think living together is different than marriage unless the “commitment” scares them and they think the problems are different without that commitment. Communication is the difficult key to making a relationship work especially since women are Venus and men...

Does item 8 fit around item 12 the pressure plates. Normally those seals or end separators are held captive in some fashion by a groove or machined space of some sort. With detailed pictures of the motors and related parts this is just based on experience from working on other brands of motors...

Relief valves rarely fail closed they typically fail open. Where did you have the shut off valve in relation to the relief valve when doing your test? With shut off valve fully open What pressure do you see with all the valves in spring loaded home position? What pressure do you see when...

The three point valve is used to control the height or position of the three point arms similar to how the loader valve is used to control movement or position of the loader and bucket.

It sounds like you have a bad hydrostatic pump or drive motor or possibly both since frequently when one component fails it contaminates all the drive components in the circuit.

what voltage do you see when engine is running at 3/4 to full throttle? What you are describing almost sounds like voltage regulator could be starting to fail and over charging the battery causing them to fail prematurely.

If my memory is correct there was more than one option on how the choke and throttle were integrated. Can you see what activates the choke? That is were I would start looking to see if there is some adjustment screw in that linkage assembly to allow throttle to rev higher before activating the...

My wife and I will frequently split a meal if at a restaurant and bring leftovers home for another meal or two. I have never liked wasting food yet am amazed at what people throw away.

There might or should be adjustment on when the throttle engages the choke. You want engine at full RPM before choke is engaged. Some models had a little lip or detent so took a little extra push to go from throttle to choke.

If my hands are greasy I just pick up a handful of dry dirt and scrub them like washing my hands. The dirt absorbs the grease and the dirt wipes off my hands easily. If one handful isn’t enough I do a second round. Dad always said that grease is cheaper than parts.

Your 445 should handle that but like big tiller states you may need some front weights when that bagger is full of wet grass or support caster wheels on the rear.

Suction side with hose clamps is where air can be drawn in. Check to see if the hose has hardened or cracked with age. Also check to see if soft and spongy from age. make sure clamps are tight.

The tank line is not gravity feed. In designing the filter and cooler circuit you want components that will handle the maximum return flow with minimal pressure drop or loss. A good return filter will have a bypass valve usually in the 30 - 50 PSI range to handle surges like cold oil start up. A...

Triple check all of connections on the inlet line to the pump to confirm they are tight and not leaking any air when under vacuum. If there is a rubber hose on the pump inlet check that for cracks or if soft and collapsing under vacuum.

Item 8 is required for the motor to operate correctly. It appears to be the seals for the pressure side load feature on the motor. High pressure oil is fed into the backside of item 12 (pressure plates) which pushes them against the gears limiting the side clearance and leakage or slip past the...

I would confirm that your loader valve has regen feature before changing anything. First would try pushing joystick farther to right while dumping to see if moves similar to putting lower into float. If yes hold joystick there and try operating the diverter. Note: it will move quickly but test...

Do you have a diagram or schematic for diverter valve? If nothing else maybe a couple pictures of the valve would help.

Rock shaft is a complete separate system from the HST. Charge pressure is usually low in the 100 - 350 PSI depending on transmission style. Noisy is also indication of possible cavitation in the charge circuit.

On opposite end of rod circled in blue it looks like could be a cotter pin missing. Not sure what that linkage connects to though. Which piece of linkage is for rear PTO & which is mid PTO. Look at how the linkage is positioned when lever is in mid position running both. Then look at linkage...

Is it slow going both forward and reverse? Any noticeable new sounds or change in sound from cold to hot? Not sure but first thing to check is the charge pressure for the hydrostatic pump. Instructions should be in the service manual.

Will the recycle absorb moisture like gravel will? I think that would be the limiting factor on how effective it would be.

I suspect the X750 will have a tighter turning radius than the BX but the BX1850 I had approx 10 years ago mowed as well or better than my current X540. No experience with newer X7** series or newer BX series. BX might be harder on the lawn when turning.

With front mount snow blower the BX with 4 wheel drive would be a nice feature since ALL the weight is on the front axle. BX also has 2 range hydrostatic transmission which again is nice for a little extra grunt if needed. Not sure on how the mid mount decks connect on 1880 but suspect X750 had...

Why do you think the pump is bad if the 3 point is fully raised?

Correct with backhoe mounted you do not have flow to the 3 point.

I would suspect run circuit for fuel shutoff solenoid. Hook up a voltmeter or test lite to wire(s) going to the solenoid to see if you have any power on a wire with key in run position..

Start with the items that are the easiest to access then work your way down the list. Note: if your luck is like mine it will be the most inaccessible item there is on that tractor…

On most tractors there is a drop rate adjustment knob that is usually located on the panel below the seat. Possibly try opening it a little to see if 3 point will lower.

Power beyond supplies oil to the 3 point hitch. Most back hoe valves do not have the power beyond feature so you want the return going directly to tank.

I would say about 1/4 way open or more. Better safe than sorry. Suspect that valve is there for transporting to keep oil from splashing out of the breather.

You want it open enough to allow air to flow easily in and out so that you don’t create a vacuum or pressurize the reservoir during operation.

Shows how good my memory is..

Wouldn’t that be 3 or 4 times of what that vintage of tractor would have cost when new?

If a piece of crud gets between the metal ball or poppet and seat they will leak. Look into the QD that is leaking to see if there is something obvious trapped in that area. If poppet style they can also tilt sideways a little causing them to leak. Normally just pushing on the ball or poppet...

Why not mechanical drive with quick tach like used on factory snow blower or broom. Hydraulic maybe if you want to lift it way up but on a CUT without a cab you would get crap thrown at you.

If you had a mid PTO it might be possible to power a front mount mower similar to front mount snow blower

No clue on that slot in the nut unless it was meant to bent in to act like lock nut once assembled but that is 100% pure guess.

What is the “heater plug” that was missing? Does the pump housing get significantly hotter than the inlet line to the pump? I made the assumption that the 3 point working meant it was lifting a load.. so yes check to see if it will lift a load.

Yes As long as the load is spread evenly. But, if moving around will the load stay uniform across all the casters?

Where do you have the gauge installed? If teed into the pressure line you will need to operate a function to see pressure.

I am not 100% certain what the drill paths under those plugs are connected to. Could just be a small amount of fluid from the pump or the drain the complete transaxle.

I believe what you are considering Allen head bolts is actually plugs that would have seals on them but would definitely want a parts breakdown to confirm.

To diagnose further you need to install a pressure gauge in the pressure line and watch this while the tractor is operating. There should be minimal pressure when no function is being operated and then pressure should rise when lifting the plow.

Is the valve accessible? If yes can you install a gauge in the pilot line on the valve section in question or swap pilot lines from a working section to this non-working section. It could a valve section binding or a faulty joystick.

Is there a breather tube that goes from the valve cover to intake? If yes then it might be possible to get oil into intake if it is lower than valve cover fill point.

Do you have some way of covering or protecting the check block mounting surface? If yes that could be an easier solution since less risk of connecting hoses wrong or a fitting leaking. There will be a seal between the valve body and cylinder. I would expect a simple o-ring but not 100% certain...

Is there some way that you can slightly lift that boom segment with an overhead chain hoist or a jack underneath to relieve the tension on the cylinder pins. Not sure how close to end of stroke that cylinder is when sitting on stop. You should not have to remove the check assembly to rebuild...

With lift fully lowered is that bucket arm sitting on a mechanical stop? Looks like it is in picture but not sure. If on mechanical stop there should just be little to no pressure in that line to the cylinder.

Your tractor may not have them but is arms on the back of a tractor used to connect implements like a box blade or scraper blade. They are raised via hydraulics on the tractor usually the lever is on the right side

To size a motor correctly you need desired torque and RPM. Then back figure required GPM and pressure. This usually leads to some give and take since you are trying to balance available HP and possibly available flow. Starting with given flow and pressure Moss is correct that will dictate...

Does the loader curl function also shutter if load on the bucket?

Are the electric motor direct drive or is there a V - belt drive? If V-belt What RPM do you want this blade run at?

Have you checked to confirm oil level? Does the power steering work properly? Is the shuddering worse when engine is running at high RPM vs at idle? Try lowering 3 point to see if shuddering changes? On some models if 3 point lever is in full raise position will cause loader to malfunction.

Heating is a symptom of flow being restricted like a directional valve not returning to center or 3 point attempting to raise all the time.

Maybe look at some parts diagrams or if possible a service manual to see how the forward reverse works. Then make a decision based on that information. If just a shift fork or linkage might be accessible with out splitting the tractor.

On my 2400H the handle must be all the way down to the floor or the brakes drag a little. I use the brake so infrequently it never bothered me enough to look at the adjustment.

Is that a feed trough in the foreground of that video clip with skid pulling hay racks? Makes me wonder if just moving short distance on known flat ground. Either way could be interesting turning if pulling very hard.

Depends on what the OP thinks the dipper is.. Agree on needing clarification of which way the cylinder is moving

Guess need to read and comprehend the original post. Cylinder is retracting so valve is the leak point. Would look to confirm that the spool is being returned to home position via springs. Compare height of this spool vs others in the valve bank. If that valve section has work port relief it...

For clarification Which way is the cylinder moving when drifting? Extending or retracting?

Only 5742 hrs, just getting broke in😁 Be curious to guess hours on some of the old tractors like A & B John Deere’s, H & M Farmalls, 8N Fords, etc. that were built before they had hour meters.

I suspect the wings would have 1500 PSI and center 2500 PSI. Next time you use this mower mow a distance in taller grass where center and left are not cutting. Shut mower off while still in tall grass and check the motor housing temperatures vs inlet hose temperature. Do the same with pump...

Dado I suspect cost would be driving factor on if this concept is accepted. Unquestionably the dual spindle will be more expensive and the 5 or 6 foot market is probably made up of people being cost conscious since an implement they may use 2 or 3 times a year. I 100% agree that having the...

How much oil does the tranny hold on that tractor? If 10 gallons like mentioned I would be far less concerned than if it only held 3 or 4 gallons.

Where all three relief valves the same part number? Can you take pictures of how where they are in the circuit. Any make and part numbers on the relief valves?

Did you check resistance or ohms on the PTO clutch when you had the wires disconnected? I recently fixed a neighbor’s mower that had a broken wire by the clutch that would randomly work then finally quit completely. It was a broken wire in the harness to the clutch. I found this by checking...

Agree don’t look under inflated in that picture. We ran similar pressure with fluid vs without. I would suspect 12 - 15 PSI for a tire that size depending on load it is carrying. with stem at 12 o-clock try blowing a little air to see if possible core was sticking or plugged.

if center cylinder is extending and retracting fully does the right cylinder also extend and retract? Wondering if the left wing lift system has some mechanical binding preventing cylinder from retracting. What happens if you jack up the left wing and remove one of the clevis pins from the...

You are correct on left motor getting flow if right motor is turning Are there any valves in the lines to the motors? Suspect that with the two motors in series there might be valves at one or both motors. Depending on how the motors are built they may or may not be bi-rotational so be careful...

Does anyone have a hydraulic schematic for the 450 with the hydraulic traction assist - weight transfer system . In watching the video I wonder if they are simply putting a little back pressure on tank line since tank is common to work ports in float position.

Is connecting the lower lift arms causing problems or PTO?

Check for rodents in the intake and exhaust. Mice, bees, etc. like building nests or hives in those areas. Check oil levels in engine and transmission. Possibly pull drain plugs to see if water runs out from condensation build up. Check for rodent damage and nests everywhere especially where...

Best guess is there was a valve like a pressure reducing valve keeping a constant pressure on the lift side of the cylinder supporting some of the weight. Same geometry that causes front of tractors to lift when front loader is in float.

Seems like foxes are attracted to filthy rich old men…😁

Will you be working on slopes or side hills? If yes any estimate on how steep the slopes are? How well the flail works will depend on factors like type, density and height of material being cut, type of knives, etc. The T25 is at the low end of HP requirements for that flail but with HST you...

Since asking about spreader I presume you have granuals and in what concentration? I suspect concentration strength and application rate will both figure into wait time. Label should have all the warnings and application info. Does that label peel open and have several pages under cover page?

You might be money ahead to buy a different tractor to run that mower or get a pull type mower for your 806.

Not sure but would 856 or 866 arms work or possibly 1006 or 1056, etc. Not sure where you are located but have you looked at Worthington Ag. They are a big used part company in the USA.

piece of 15/16 or 24 mm rod weld head on one end drill hole for hitch pin on the other or like stated a bolt depending on what you can find available.

I suspect that is part of the confusion on the thread. What HP tractor are we talking about being used for what purpose or purposes? 20-25 HP doing loader work in tight quarters or mowing lawn, or 40 - 60 HP doing some loader work, plowing or discing some food plots, brush hogging etc. or 100...

If dropping at low idle sitting still I would suggest checking both pump and motor case temps. Not moving motor in theory should have minimal case flow while pump has all of the charge flow dumping into via charge relief.

To the best of my knowledge yes that is still a semi common feature. I believe Deere 2,000 series, some Kubota B series and BX series, TYM Branson have dual, etc.

The looped lines will show charge pressure in neutral and should have minimal change if trying to drive If trying to drive rear wheel motor will take some charge flow for flushing valve I the motor but should have minimal change in charge pressure. Does charge pressure drop just sitting...

Smaller CUT tractors with dual range HST have an issue of significant gear increase from HST to rear wheels in high range so they really struggle pulling load up hills similar to the older M & H Farmall with 5th road gear. Go fast down the road but wouldn’t pull their shadow up hill. Larger...

The enable valve is supplied by the Ps port and will operate with the “G” port capped off. Ps is the pilot pressure to the pump control. Unloading that line prevents pump from being able to come on stroke. Don’t know exact numbers but suspect need around 100 PSI for pump to start to stroke and...

The name plate is a Rexroth product and description fits the A30. Pump was manufactured 36th week of 2017.

Starting out pulling a load or climbing hills with load: HST in theory will use full engine HP in any speed range. The unknown is will there be enough torque to pull the load in high range but you can typically stall the engine so the HST is not the limiting factor. You have to stop to shift...

Try doing a search for RE 93430. That is the data sheet number for a Rexroth A30 pump. Does your pump look like the diagram in the data sheet?

I would talk to an electrician or possibly power company to find out what the rules are for installing a generator with automatic transfer switch. Not sure if there are regulations on line of sight requirements for disconnects or limit on distance between generator and your main breaker panel.

Air in a static system will show same pressure and have little to no effect on the charge pressure. How difficult is it to access the pump? To isolate a leak in the charge circuit I would disconnect the line from the “G” port on the pump feeding the pilot controls. You will not be able to...

In the pictures it looks like mower lift pivot point is in front of and above the front axle. While in float and driving forward resistance to mower moving makes the front of tractor rise and want to raise and climb over the deck. Simple solution sounds like filling tires or adding 125#...

No charge pressure in the front pump circuit with the motor hoses looped when no movement is being requested points towards a bad HST pump. In neutral you should see full charge pressure in loop.

Skid steer tires might have a different style side wall in the bead area to reduce flexing while skid turning and protect lip on the rim.

Is it losing weight because pushing mower lifts the front similar to how a loader lifts front of the tractor? If yes that would require some linkage from deck lift to rear axle to transfer that push behind the pivot point. Loaded tires would help along with wheel weights if you can find some...

Richard Thanks for posting that schematic. Per schematic the charge pump is common for both front and rear drive pumps so you should be losing charge to both front and rear circuits. Both axle drive motors have flushing valve built in so to diagnose bad motor you have to check motor case flow...

Not familiar with tool cat circuit, do they run separate pump for rear motor and front motor? If yes then would point towards a leak in front pump or front pump charge circuit. Do you have the hydraulic schematic for this machine. If yes can you attach it to this post so we can view it.

Where you losing charge pressure with the front motor disconnected (hoses looped) or with motor actively in the circuit? I suspect motors connected and if so sounds like you a pump or motor leaking excessively causing loss of charge pressure when system warms up.

Drop spreader is fixed width while rotary spreader is a function of travel speed and granule weight and or wind speed. I think most rotary spreaders figure 5 - 6 ft at normal walking speed.

A possible problem with HST on hills is controlling load or stopping going down hill. With HST you are decreasing the pump displacement to go slower or like gear you can idle engine down to provide engine braking - hydrostatic braking. Most HST have wheel brake pedals on same side of tractor as...

Can you access and or remove the bearings without totally destroying them.Frequently a bearing supplier just requires the shaft Diameter or ID bearing outside diameter and thickness along with type of bearing. If you are lucky there will be a legible part number stamped on the bearing to make...

Does that tractor have some form of power beyond plug or feature in FEL valve? If this plug is leaking or has a bad O-ring the oil will go to tank at low pressure so loader will work but 3 point won’t.

Possibly try lowering the 3 point hitch a little to see if the noise stops. Chance that feed back link is borderline on adjustment so it randomly thinks the 3 point needs to raise a little more.

Glad it was a simple fix.

The Kawasaki engines are very good engines so wouldn’t hesitate at $200 difference. The X500 series Deere have a heavier duty transaxle vs X300 series and have far less reports of transmission problems but are also more expensive. Not sure on Husqvarna but believe have same or similar transaxle...

When “self feeding” Does reversing the feed rollers change direction the rollers are turning? If yes then it is a matter of friction between feed rolls and material being fed into the chipper. The chipper blades are pulling the material past the feed rolls. Is there an option to increase spring...

First thought is did you have one of remote levers locked in detent position or 3 point asking for raise all the time. Either of these would keep pump at relief pressure creating heat. This based on your tractor having a gear pump.

Will the center lift cylinder fully extend or lift? If not previous owner may have swapped out a cylinder for some unknown reason and like sportsman states it will not work properly then. It can be made to lift lower by connecting all of wheel lift cylinders in parallel. I.e. connect all three...

HST loses power due to charge pump being 100% power loss and heat generation along with a little more splash frictional loss. Main use where HST is potentially less desirable is steady full draw bar pull like plowing a field. Doing PTO work doubt you will even notice the difference

You might require more than one machine for those tasks since not sure a farm tractor would doze trees for a fire breaks. Maybe a twin track ag tractor would depending on tree size. These potentially would require significant branch guards to protect hood, windows, underside, etc Probably be in...

I have seen belly pans used for this application. A piece of corrugated sheet steel works reasonably well and is slippery.

What seals item 4 to item 10? My Branson has a gasket in that area.

I think you need to clean that off to determine where the leak is.

I think extend is phasing but again would not bet the farm on that. May have to hold in extend or raise for 30 seconds or more but you should be able to watch cylinders move. You can do this with tractor at idle or just above idle. Rephase cylinders have a small passage that bypasses the piston...

For wing fold the cylinders are single acting not for wheel lift If you study the parts schematic on page 82 they show cylinder 2, 3 & 4 as double acting plumbed in series. Note: they do not state which cylinder is main lift, right nor do they state rod diameter so doing a little math I...

Matt, Pictures and your hose routing provides the required detail on how this lift system is designed to work based on the assumption plumbing and cylinders are as left the factory. To raise mower: Oil from tractor feeds blind end of center lift cylinder. As this cylinder extends the rod end...

Matt, A question that should have been asked is did this mower used to work and now suddenly doesn’t? If yes what changed? Hose break, cylinder leaking and repaired, etc. I am wondering if the wheel lift cylinders are a master - slave system where the main lift cylinder rod end is connected to...

What you are seeing sounds like charge pressure when hydrostatic drive is in neutral. Asking to move forward or reverse will increase pressure in one of the lines. Pressure will only rise to point of what it takes to turn the motor.

Agree wing wheel lift cylinders are double acting but do appear to be connected that way. If valve have float I would just put everything in float to see what happens. Not sure what model Deere that mower is hooked to Why does open or closed center matter? The valves are most likely cylinder...

I would start by tracing the lines from lift cylinders to see how they are connected. Take notes or pictures showing: what blind or cap end of main cylinder is connected to What the rod end of main lift cylinder is connected to What the left and right wing lift cylinders blind or cap ends are...

Interesting on drive motors still working with safety arm raised. Is this a double or Triple pump? I can’t tell on the picture.

If you lift the safety arm do any functions stop working? Would suspect that solenoid might unload one section of the pump but doubt would unload both sections. Be interesting to find out what that does.

Do you have pictures and description of how you mounted and plumbed the new remote assembly. My first thought is that it is plumbed incorrectly and over pressuring the system.

I would suspect a bed connection or broken wire vs a bad solenoid causing this problem.

What sensors or items would cause the reduction of fuel pressure or derate engine? Faulty pressure sensor cause this? Failing lift pump to main pump? EPA component failing causing limp mode? Not sure what components throw codes

I believe the push - pull style cables are called Bowden cables. If you have length and end style possibly try doing a search for Bowden Cable. They are getting more and more common so should be able to find replacements.

Looks the one with ag tires also has rear wheel weights. Unless some real odd ball size they should be worth some money.

I clean my deck whenever sharpen blades or cut when grass is wet and gummy. I can hear when deck is clogged it gives off a strange whup , whup sound. Always scape them off in fall for winter storage.

For light cutting that should work just fine. Around here Woods is common since factory is 20 miles away.

There might be two set screws located 90 degrees apart. I would fully remove all the set screws and fill the hole with penetrating oil at let it soak. Heat and or an air hammer on end of shaft while pulling helps break the rust loose also.

Problem we had with the 420 was no live PTO so when hauling manure it was sometimes a challenge to get PTO started while trying to drive through the field if load was against the beaters.

I have had grass build up in the pulley on the crankshaft causing belt to slip especially when grass is damp or belt gets wet so would check for that if belt is slipping. Another thing would be engagement cable adjustment. Does it pull the belt tight. Does belt look shiny and smooth on V...

Method for estimating height From Boy Scout days. Take a stick or post of known height like five or six feet. Put this at base of the tree. Now walk away from the tree until the height of your thumb matches the height of the post with your arm fully extended. Note position of top of your thumb...

It looks like the wing wheel lift cylinders are still extended while center section are fully retracted if plumbed correctly all of the wheel lift cylinders should fully retract when lowered. Will the wing lift cylinders retract further? The diagram calls them phasing cylinders

Wise choice if it is not a threat to anyone walking past or mowing around it.

Parts diagram I found shows a single belt going to a gear box on rear axle. I couldn’t tell for sure what engages the drive from the diagrams but it looked like removing a cover would expose the gear box and drive belt so you could potentially watch what happens when you engage drive and hold...

Does the 400 specify low viscosity hygard? If yes that might be a little harder to find an alternative fluid that meets that spec.

Only way I know is if you can remove a cover or shield and watch the belt while mowing.

Does this mower have the rubber friction wheel drive? If yes watch the aluminum drive vs driven rubber friction wheel to see which one is slowing when mower slows. If aluminum look at the drive belt, if rubber friction you need to look at friction wheel components. The friction wheel is a...

Do you have a volt ohm meter? If yes you can check to confirm getting power to the glow plugs. You can also disconnect the electrical connection to the glow plugs and then measure resistance (ohms) on each plug from electrical connector to ground. They should all be similar reading. My Branson...

Do you have a voltmeter or test light for 12 VDC circuits? If yes I would suggest checking for power to the starter solenoid when you turn the key. If no power there you need to start tracing the start circuit to what connection is not being made. Not familiar with your tractor but are all of...

Wish you would keep that kind of weather down south.🥵

I just looked on tractor house and was amazed at prices for a 420. Might want to look at that site as a point of reference.

was there a lot of loader work done with the tractor? Just wondering if that could put additional loading or thrust on that assembly especially if on side hill or turning a lot.

That is quite the fleet of old blue iron. I do miss the simplicity of the 5000 & 5600 we had 40+ years ago.

Or provide a replacement vehicle while yours sits? I have had recalls and my dealer provided a loaner while my vehicle was out of service. Suspect that is dealer decision and not Auto company.

Idle the engine down for smooth digging and rev it back up for travel. Running at 2,500 RPM should be fast enough to keep engine cool yet might reduce flow enough to make operating smoother. Inexpensive option to try vs changing ALL the directional control valves to have better metering...

Leakage depends on the quality of the valve and are the cylinders not bypassing internally. You can ask dealer if there is a leak down spec for that tractor but don’t be surprised if there isn’t one specified.

Not sure on damaging anything going full stick but is concern of system pressure stalling the engine and or what are the pressure spikes when you turn, feather etc. I think you need to get a gauge and fittings or phone a friend that has them to determine what is going.

Are the hose ends the same where they connect to the motor and PO check block? If yes could you just loop the C1 & C2 ports together? This would remove the track drive motor from the rest of the circuit. If you can feather the control that would point towards a problem in the motor or track...

Interesting thought on track binding but why does it work full speed reverse and not when trying to operate at less than full speed? If this unit has blade on front should be easy to lift both tracks off the ground with blade and bucket and see what happens. Duhh this is a dumper not a mini ex...

Idle the engine down some is the same as installing a smaller pump and will give you an idea on if that helps or how much it helps.

Bob does this model has reservoir for the hydrostatic transmission? If yes does the oil look foamy in the reservoir?

Glad you found the problem and was a simple inexpensive fix.

Looks like it does a good job on the brush

Is that an air cooled or water cooled Kawasaki engine? In theory water cooled should be more consistent temperature as long as radiator is not plugged with chaff. If like my X540 it collects chaff on radiator screen and around the cylinder heads. I blow it off every couple of uses or more in...

What you are saying is 100% correct if the BX had a return filter. The only factory filter on a BX is in the charge circuit not the implement circuit.

There should not be any pressure or flow under those caps. Just be careful since there might be some spring loaded parts that will want to be escape artists. Depending on lever or joystick is oriented it might want to push the valve spool so be prepared to control that movement also.

Maybe I can help explain what to look for and why when watching the hoses going to the travel motors. When trying to drive one of hoses going to the motor will or should free flow through one of the PO checks down to the motor. This hose will see some pressure in trying to drive the motor. If...

Another thought is if this is before the loader valve where is the relief valve located and operating the loader would then also pressurize the tank port. I like your thinking but might need a little fine tuning.

2manyrocks, In that picture of the block for track motors the schematic on the side of the block shows being dual pilot operated check valves C1 & C2 should connect to the motor. Have you driven it down a hill? Curious how it will respond with those po checks in the drive circuit. I tried a...

Are there any marking on the the blocks bolted to side frame that I believe are labeled LTR and RTR which i presume is left track and right track. It looks like there is valve sticking out one end but can't see the back side. These could be some form of pressure control for the track motors or...

The pictures show a double gear pump. I suspect one pump feeds left track and other feeds right track. Is this correct? Would suspect that while trying to feather the track drive the valves are restricting flow to the point of reaching close to system relief pressure but that is something you...

Does the curl dump have detent on it.? If not I don’t believe that valve has float since the spring caps or covers appear to be the same length while detent option the cover is usually longer

Would you care to explain how the problem is the loader valve?

Priority valve is a flow control with a totally separate valve for relief function. Priority valve would typically not have any pressure setting. Kubota clearly shows the relief in the schematic and then also as part of the priority valve assembly. This relief protects the pump in this system...

Doubtful there is an off the shelf front mounted pump option for that tractor. Problems are how to drive them, where do you get oil from, etc. There are rear mounted units that run off the PTO and include a separate reservoir but they are not a low cost item.

If this is for occasional use and 400 ft of driveway I would look real hard at simple 3 point mounted blower provided your tractor has 3 point and PTO. Simple, inexpensive and proven design that works along with can leave loader on tractor.

How did you determine that excessive flow is going to the filter? If and I repeat if you are talking about the filter that screws onto the front of the transaxle that is filtering the priority flow that goes to steering first and then into the HST as “charge” flow to keep a positive pressure on...

22 HP for 54” blower sounds a little under powered for heavy snow. I also didn’t see the weight nor any dimensions so curious how much loader lift capacity you require along with rear ballast.

Has it been stored inside out of the sun? If yes that helps prolong their life but 20 years I would probably consider changing them especially if had plans to use the loader for extended period of time.

The newer machines with power shift do have either pushbutton or toggle for charging gears but you still use the clutch to stop and start. Only spent a couple hours on a IVT tractor last fall and I think you could just pull back on the speed control to stop then push forward to take off with no...

Every power shift that I have driven requires pushing in clutch to stop and start. Clutch is possibly lighter than conventional gear but still requires pushing it.

On the BX the factory filter is in the charge pump circuit for the HST. So low pressure circuit Standard spin-on filters are typically rated for around 100 - 150 PSI with normal operation at 50 PSI or less. I do not recall if it has been confirmed that this is the filter in question but...

Well sounds like we can scratch another idea off the list. Oil clearing up in 3 minutes kind of points towards a splash aeration but still doesn’t explain what changed to cause this. Another potential silly question but was the fluid level different before you changed it? I.e. a little fuller...
