Is that part plastic? Is sure looks like it. If it is it will be a cap for a fill port for something on your machine. Transmission, power steering.... It will not be involved in some feature under stress like a loader, or movement of the tractor. However, if it has been off i.e. open for some...

Sodo I see you have a small excavator. Could you disconnect the upper end of the hydraulic cylinder and with the cylinder lying horizontal and the dump bed held up with your excavator, cycle the hydraulics and watch for smooth movement in the cylinder. Next, raise and lower the bed using the...

oldnslo E-Z dumper's web site mentions a Monarch double acting pump. Double Acting Monarch Hydraulic Pump With 1 Quart Reservoir Dave M7040

In some regeneration modes (mode 3) power output is reduced. Do you have an Operators' manual and have you studied it? Dave M7040

Does it look like this one? Dave M7040

Jumping a starter is easy and my marked up photo shows you how. You need to recognize that doing this bypasses any safety device on your machine. It is best to have someone in the seat. Expect a few small sparks as you jump the two terminals I would like to see a photo of the top of your...

I have provided you with the 3 pages from the WSM explaining how the fuel and temp gauge work + wiring diagram for whole machine assuming it is equipped with OPC Dave M7040

If the chain has repeatedly come off after the set screws loosens, I would suspect the chain is bent and should be replaced. JWR's suggestion of drilling a depression for the set screw is a good one. In the top right corner of the frame holding the shafts for the reduction box, a carriage bolt...

Does your tractor have a loader, a loader with third function valve, or other hydraulic features like top and tilt. Have you modified it or added to it or is is as stock as when it left the factory? Dave M7040

I have the LA1154 assembly instructions as they often contain the procedure for installing a third function valve. Tell us what your problem is. Dave M7040

What model of B7200 do you have...... type of transmission and is it 4WD PTSG's advice should be followed! Look at the front of your engine and see if there is a hydraulic pump being driven from lower crank pulley. Dave M7040

Suggest you join the Orange tractor farm and then contact member 007kubotaguy who is often parting out older Kubota L's. OrangeTractorTalks - Everything Kubota Dave M7040

Please check if your loader valve has 7 ports. Loader valves with 7 ports will have a "Power Beyond," feature which will be supplying the rear of the tractor for 3 pt hitch and remotes if any. Advise the model of your loader and describe the valve...... joystick direct to loader valve body or...

Any chance you have changed any loader hoses? The loader valve will have a power beyond port which feeds the rear remotes if any + 3 pt hitch. When you are having box blade issues does the loader work properly or does it too also act up? Dave M7040

Thanks for the photos. The blower was originally used on a ford tractor and now is on a different one. Was the length of the pto checked so there is no bottoming out when blower raised and there is sufficient overlap. Dave M7040

I can understand your breathing challenges and commend you for continuing to try and get chores done. My wife of 54 years had lung issues and died this past Aug. Could you please post a photo of the head of the bolts you are using as shear bolts. A closeup photo of the shear bolt hole. Has it...

Unlike Kubota and most other tractors who use the transmission as a reservoir for the hydraulics, these tractors have a separate reservoir under the seat. I think you could use any hydraulic fluid including Dexron GM automatic transmission fluid. Dave M7040

My comments may give you a few clues. Kohler sells its small engines to many equipment manufacturers so they have an industry recognized way to interface their engine with the equipment. In my case it was a Toro Zero turn. Near the engine there was an electrical connector which tied the engine...

I have a WSM for a similar model. It has an excellent description on how the tractor's hydraulic system feeds a more traditional brake valve. You machine may be similar in design but I am guessing on this. I hope you find the info helpful. Dave M7040

Read the material I will provide below very carefully. The OPC did exactly what it was supposed to do. When you got off the seat something like the pto was engaged, the HST pedal was touched or its switch not properly adjusted. In your description you should be clearer. 'will not start back...

Thanks for advising what you found. It helps everyone learn. All too often someone gets a solution and then just disappears. Dave M7040

JWR I certainly agree there are other possibilities. I try to pick the ones I have experienced and which I found easy to decern if the cable to valve spool where the issue. If the owner finds my suggestion is not the problem he can quickly move on to what will be more difficult and complicated...

Your joystick has a lock which I can see in your photos. Engage the lock which can only happen with the joystick in the neutral position. Under the right side of the tractor about where a footrest would be is the control valve protected by a simple to remove shield. With the joystick locked in...

How many hoses connect to your loader valve. 6 or 7. Do you have any rear remotes in the tractor and what is their behaviour relative to what you describe for the loader and 3 pt hitch. Does your loader valve have a brand name and label on it. What make and model info exists for your FEL. Was...

Try and find the suction line for the hydraulic pump. Sometimes they are rubber. Other times metal sections with o rings sealing the sections. Air can be drawn in where no oil will leak out when sitting. Air in the system will limit lift ability. Dave m7040

You have mixed up a couple of hydraulic lines. Start by telling us how many lines connect to the loader valve. 6 or 7. Clean the valve body to make the port letters cast into the valve body visible. Dave m7040

Your tractor has two timers. An OPC timer and an engine stop relay timer. I have attached a couple of WSM pages so you can check yours out Dave M7040

Many years ago I was an accident investigator for the Canadian government. I was sent to the scene of a farm accident where the tractor operator was crushed and suffocated by a large hay bale. He had been working on the loader and reversed the bucket hoses. He thought he could mentally...

In a hydrostatic transmission the main tractor hydraulic pump has next to no involvement in the HST operation. Suggest you post in a JD section of this forum as your problem is really not hydraulic Dave M7040

Question was answered on Orange forum. North American tractors do not come with brake light switches. Manuals cover many countries models. Dave m7040

The video forum member Peace supplied is excellent. Here is the section from the WSM on removing the pto shaft. Does your machine have a mid pto and if so how is it acting. Before starting to take things apart, make certain the pto control levers are fully engaged. Dave M7040

Check all fasteners securing wheels to machine. Lug nuts but some designs have the wheel center secured to the wheel rim Dave M7040

My M7040 has a lever above the brake pedals which you pull up on as you depress the brake pedals. You should have the both pedals locked together before using parking brake. Make certain both pedals have same adjustment. Dave M7040

Put a shop vac on blow. Put the end of the hose over the fill hole to increase the pressure driving oil to the pump. Sometimes this can be enough to get things started Dave m7040

Suspect any quick connects in hoses going to loader cylinders. First open and re-set the connectors. If problem persists, swap loader arm hoses for bucket hoses to see if problem now moves to the bucket operation. Quick connects can and do fail internally. When swapping hoses, take great care...

In my experience with three different brands of rear mounted blowers, that is exactly how the auger shear bolt is placed. Dave M7040

likely the auger shear bolt situation requires a carriage bolt. The square shank under the heat of the bolt secures the bolt from rotating while the nut is tightened carriage bolt Dave M7040

Did you have your multi meter set to measure AC voltage when checking the dynamo output? A common mistake owners make is to have the multiimeter set to measure DC voltage for dynamo output. Dave M7040

A forum member named on the Orange Forum Lugbolt wrote a diagnostic procedure for dynamo equipped tractors which is what the open station B3030 has I have attached it. Dave M7040

The attached procedure will help your thoroughly check out your cylinder. A cylinder can bulge in the middle. In this situation the piston seal will not leak at the end of the strokes. Dave M7040

Thank you, unfortunately my wife's condition will only get worse. Dave M7040

No barb does not exist on these valves. Plastic end was smooth and unbroken. Judging by the simple wire clamps Kubota uses all along this return line they are not expecting any pressure. I never have water issues with my fuel but that does not mean condensation coming back from the tank affected...

In my area a major storm is coming and because my wife is very ill, I was readying the M7040 and blower so I could keep our lane open for medical supplies or an ambulance. I backed the tractor out of its storage location and was getting ready to drive it into my heated work shop. When I got out...

I start my similar sized generator engine running on propane with a cordless drill. I was making up a bendix drive system with socket of the correct size (23mm) welded to it but my next try will be with a power bar rachet to act as the bendix drive. You need a drill with some guts. I have...

Check you do not have a rear remote control valve that has not returned to neutral. These valves can be draining off the hydraulic pressure making the FEL work slowly. Dave m7040

There are two styles of loader valve controls. A 4 position bucket control and a 3 position bucket control. You need to figure out which you have because copying someone who has a different valve than you do wont work. You also need to find and then study the hydraulic block outlet type on...

If you are doing this regularly, why not make the special stretching and compressing tools Kubota's details in their loader shop manuals? I have attached the jig details for a different loader to explain what I am talking about. I think the idea of using the jig is to avoid any twisting of the...

The parts diagram you posted describes the cylinders as have a valve in the base of the cylinder. Likely it is some form of load check to prevent the cylinder from suddenly moving if a hose burst. A small leak in this valve would allow the cylinder to lower. I would remove the cylinder in...

We need the spec's for the other motor also. You also need to do the torque wrench test I suggested Dave

Post the brand and spec's for your motors. You need to have an idea of the torque requirements of your drive system. A quick and dirty way would be to remove the motor, rig up a way to connect a simple torque wrench to the drive and see how many foot pounds is required to rotate the wheels...

Why do you think you need a new valve? The one you have has 7 hoses which means a replacement must have a power beyond option. The common mistake owners make is buying too big a flow rate replacement valve. What this does is rob you of fine control of the loader. 10 gpm or even a bit less will...

Check your private messages. Envelope symbol top right of page Dave M7040

Go to a dealer and bring a USB stick. Dealers have access to the main Kubota documents web site so if they are feeling helpful a few seconds and the pdf form of the manual is on your stick. Some dealers will charge for a WSM. Dave M7040

Does your loader valve have power beyond? The arrow "from implement," would be the loader valve power beyond port providing hydraulic flow back into the tractor system. Not certain if you have power beyond. 6 hoses on loader valve means no power beyond. 7 and you have pb. Most valves can have a...

The type of transmission will result in different hydraulic circuits. What type is yours? Manual, Glide Shift or hydrostatic How many hoses connect to your new loader valve...... 6 or 7? Dave M7040

Almost always a plumbing error. Do not take the pump apart as you will create greater problems. The clearances in modern pumps are beyond the tools and ability of most mechanics. Your hydraulic pressure will always be low on an Open Center system until the flow is restricted so your test can...

Here is the steering cylinder of the WSM. Unfortunately images leave a lot to be desired. Dave M7040

I have had good luck using a puller plus an air hammer. The rapid pounding of the air hammer will tend to jar stuff free where just pressure wont. Dave M7040

The parts illustration clearly shows a two section pto shaft with each section having two U joints and each being able to telescope. Deviating from this design carries significant risk. Woods would not have opted for this more complicated setup just for fun. This is not a China designed...

I regret that my advice is correct especially with the valves you are working with. I looked over the spec's for the valve you posted. The spec's are even worse than I expected with a max tank port pressure of 150 psi. Normally I see 450 psi as a valve's tank port spec.. When your second...

Your plumbing is completely wrong!!!! First, your first valve in line needs to have a power beyond circuit. This is usually an optional sleeve or plug which you buy and install. Since your latest valve is the newest, see if you can buy a power beyond kit for it. The power beyond option is...

I do not think you have the pto power to operate such a unit. Landpride recommends 52 pto HP. Consider that a minimum. Your NH has 44 to 46 pto HP depending upon the model of the main transmission. The manual transmission sending a bit more power to the pto. If every HP your engine can produce...

Your point: Normally a backhoe is just 2 hoses and when the backhoe is disconnected....those two hoses hook to each other It all depends on where the Backhoe valve is in relation to the relief valve. On some machines the BH valve is fed first in line from the pump. The BH valve then needs a...

I did some on line searching for the owners particular model. I think the reason it is not listed in the Bervac material I provided is because the blower is very old. I say this because it has a 3 blade fan. All their new models come with 4 blade fans He needs the pto shaft shear bolt it would...

Start asking dealer and Kubota headquarters about Kubota programs in some areas for crank case vent system heaters. A known problem for some models in cold areas. Some models require an alternator upgrade to handle the heaters used to keep the positive crankcase vent system from freezing tight...

This attached page from Ber-Vac translates some part numbers to real bolt sizes and grades. I suspect the owner has mis types the actual model he has and perhaps it is a 74 *PN 657199-10MM X 55MM GRADE 8.8 There are other 74 blowers with different shear bolts Dave M040

Do the two tests shown on this page from the WSM. Do them carefully!!!!!!! Once you have done both, report back especially the two resistance values. Dave M7040

Are these mower conditioners not driven from a conventional pto shaft. The only hydraulics are to raise and lower but not drive the implement. If I am correct, then the hydraulic flow needed will be minimal. Dave M040

I live north of the St Lawrence river and maintain trails on the farms of my brother and myself. I like an inverted blower. When snow is not too heavy I can motor along at pretty good speed. A much higher speed than you could do with a conventional 3 pt blower. Greatly reduces the time to...

This is a question not a statement! Could the control valve for the implement, in this case blower but previously who know, have been a spool valve for a cylinder and not a motor? If this was indeed the case how would this "mistake" show itself in pump damage? Dave M7040

Here is the required GP reading from the WSM. 0.9 ohms This next test is to verify the GP's are being powered both during PREHEAT and also START on the key switch. I have not readup on how your GP's on time is controlled. If it is all manual then the block heater is no problem. If there...

I suggest rather than focus on the current draw of all three GP's, you need to verify the correct function of each one. Disconnect the lead between the three and then measure the resistance of individual ones to ground. Have you installed a block heater as this can affect starting in unexpected...

Most larger cities have hydraulic specialty shops who can repair most cylinders. These places have access to seals and wipers you will never find especially for older machines. Dave M7040

Have you done this test of the timer relay? Failed diodes in small tractor circuits usually are there to stop things from happening such as an electric clutch seeing power when it should not rather than preventing starting. Dave

If you do not have power steering, then perhaps getting the pump for a model 870 with power steering would give you the flow you were looking for. Dave M7040

Some machines which have worked in a corrosive environment i.e. seaside, where road salt is used, have corrosion between the starter and the engine block. The starter relies on a good connection to the engine block for its electroical ground. Dave M7040

a former Kubota mechanic. I know him and am offering the owner some assurance that advice from this person should carry significant weight. Dave M040

The individual who made reference to the service bulletin and dumping directly into the transmission instead of the pump return is someone whose advice should be regarded as being much more knowledgeable than most on the forum. When I have a problem I cannot solve I turn to him for advice. Dave M

Your system has errors in hose and pipe connections to act like it does. The power steering would be open center. There could be a priority flow control valve whose job it is to ensure that the power steering always has the flow and pressure it needs... Dave M7040

A couple of suggestions for you. I spent a lot of time researching front blowers on B7100 while helping a friend. The original design by Kubota had solid steel support bars running from the bell housing area of the tractor up to where the blower was attached. These bars were 1" solid square...

Your starter relies on contact with the engine block to complete its circuit. It happens with old tractors that the mounting face of the block where the starter sits gets rusty to the point that only poor electrical contact to the starter body occurs. Clean the block mounting surface and try...

This post is intended to alert some JD owners that JD has used closed center hydraulic systems on some models. The difference between Open Center and Closed Center is very important in selecting valves for adding rear remotes. I checked and the JD 970 is open center which will make this...

The M7030 is actually a Fiat painted orange. You first need to make certain each GP is working. Disconnect the wires from the GP's and then measure the resistance to ground of each individual Glow Plug.. They all should be close to the same value. If one is different then replace all of...

On the B7100 the only fuse associated with the GP's is the main fusible link. If you blow it nothing works. Machine is different than the B7800 Dave M7040

I do not understand "I used power beyond ports in back." Are you talking about ports for a back hoe? A simple spool valve will not last with pressure on the T port. Does your spool valve have a power beyond feature as this would be an integral part of the installation. Dave M7040

The difference is in system design...... open center on Kubota and most smaller tractors. This system uses a constant displacement pump meaning for each revolution of the pump shaft a fixed volume of oil is moved. If the oil flow is stopped and no relief valve to maintain the flow the pump and...

I am going to give you a bit of a generic answer believing your Ford is a Japanese tractor in disguise. If the glow indicator is a glowing piece of coiled wire, its real purpose is to lower the voltage applied to the glow plugs to around 10.5 from the battery's 12 volts. The key switch plays...

The high WSM pressures are the HST pressures. What concerns me is that it is most unusual for Kubota to set up a new machine far above the stated relief setting. I am left to wonder if, in installing the loader and third function, a plumbing mistake was made. Dave M7040

oldnslo is addressing the issues very well!! The one aspect of the motor input you have not mentioned is tractor engine speed. The hydraulic pump, assuming it is an Open Center design, will have an increase in flow proportional to the increase in engine speed. If you are currently doing your...

By converting a mechanical thumb to a hydraulic one you may have created a situation wherein, one hydraulic cylinder can be pushing against a smaller hydraulic cylinder and in doing so amplifying the pressure in a circuit. This is similar to the situation where owners destroy bucket cylinders...

From memory there is a new improved suction line. Suction line problems tend to aerate the fluid resulting in fluctuating oil levels and changes in sound. Look at post #5 in the thread linked below. B26 Dave M7040

rScotty I have attached the LA534 assembly instructions. Dave M7040

Just to add to what has been said. The BH valve has its own pressure relief valve. When the pressure relief valve operates it needs a fluid path back to the reservoir hence the third connection. Dave M7040

By removing the bucket lines from being able to operate, it will reveal if the loader hoses are in the correct position. You said you checked the loader arm and bucket cylinder hoses are in the correct position by relying on the color caps and plugs attached to the hoses and quick connectors...

I suggest you try disconnecting the quick connects for the loader cylinders and then see how the 3 pt hitch responds. Relying on the color tags can be misleading. With two bucket quick connects disconnected completely it will be interesting to see if the loader arms work properly. I do not...

Further to my earlier post suggesting two or more lines have been inadvertently swapped, I am attaching the one critical page from the LA765 Assembly Instructions. I have also marked up that same page with the colors Red Green and Blue. These colors have no importance other than my marking...

Typically cause of foamy oil is a leak on the suction side of the hydraulic pump letting air enter the pump. Look for a piece of rubber hose on the suction line. Often used to join two pipes together. It will leak air in but you wont see fluid leaking out. Dave M7040

Typical cause is a hydraulic line on the loader valve in the wrong port. However, it is always wise to ensure quick couplers for the loader are properly seated. Disconnect and then reconnect each of them. If the loader valve has 7 lines it has a power beyond feature. Power Beyond is used to...

post #5 Yes our lowering speed control spins freely, though I can still adjust it by hand. It doesn't affect this problem though. I guess I'll play with it a little more. Dave M7040

If this is a Kubota Type 1, I do not see the rectangular metal block with the two special fittings. Please double check and post a photo of the door sticker. Where are the two hoses going to? Dave M7040

The starter relies on contact with the engine block for its electrical ground. There have been cases with older tractors where the mating surfaces are too rusty to provide a ground path. Simple test is to run a battery jumper cable from the battery negative post to the starter frame or...

As along time M040 owner you seem to have an unusual setup and one I never heard of before. Is this configuration one done by a dealer who has done a number of similar ones or is this an odd duck? Kubota M7040's can have one of two possible hydraulic setups labelled Type 1 and Type 2. It is...

I am inclined to think the OPC controller is bad absent chewed or rubbed wiring. Dave M7040

I would point out that oil burning furnaces and boilers had many problems when low sulfur fuels were introduced. These problems initially appeared in Alaska as winter arrived there first during the mandated change in fuel requirements. The greatly reduced lubricity caused the pump on the oil...

I find the key is first having a water block filter on the outlet of your bulk tank...

It makes a big difference which rear remote you connect a single acting cylinder to. Many SCV ports have load check valves in them to keep a cylinder from creeping down. This load check may keep a cylinder from lowering by gravity Owners' manual if read carefully usually spells out the one to...

The instructions you need are in the Assembly Manual for the loader. As an example, I have attached this manual for a M7040 with LA1153 loader but expect same or very similar. Working on the M series ( and other tractor) hydraulics requires great care or the main pump will be destroyed. Your...

Cross over relief valve. It will dump excess pressure on one side hydraulic into the opposite side thus avoiding pressure spikes. Dave M7040

JD 2020 tractor? Usually with hydrostatic power steering, the visible seals are only for keeping out dirt and water. The seals/O rings keeping the hydraulic pressure in are inside the steering box. Dave M7040

Let me start by saying I am, not a JD expert. Over many years, from looking at their electrical schematics and WSM for models like the 2210, my impression is that the various diodes are part of the safety circuit designed to protect expensive components from reversed battery jumper cables or...

JWR There are two possible hydraulic situations on these M series. Kubota calls them Type1 and Type 2. Type 2 tractors have the following label on the lower edge of the right door. The Power Beyond loop I referred to in my previous post is this loop of metal tubing seen on the warning label...

M5040,6040, 7040 steering joint For owners of M*040 and M*060 with cab. There is one splined slip joint in the steering shaft that owners are not greasing and locally one has seized. It is only visible with the hood open. Dave M7040

In re reading your post several times I was puzzled by your comment that although the solenoid had two power wires and a ground wire, the two power wires were joined together a short distance from the solenoid. I am lucky to have a Kubota WSM in pdf form because you are able to blow up...

pat32rf I am looking at the diagnostics explanation for the stop solenoid for my Kubota. The solenoid connector has two terminals and as I have marked with the red arrow so it must use the tractor engine block as its ground. Although it in reality has three wires to make it operate, one...

What I noticed when reviewing the 4105 photos on photobucket was the photo of the fuse and relay panel showing a K1 Fuel Run relay and K2 a Fuel pull in relay I am going to study my Kubota WSM wirng diagram for the fuel cut off solenoid as I expect most manufacturers are doing it in a similar...

OK I understand, you are Not talking about a cut off solenoid on a 1980's version of an IH 584. I could not understand how it would be possible in the 1980's but assumed since that was how I, at 70 years of age, read your post, was how it had been built. Thanks Dave M7040

Would it be possible for you to provide a photo of your installed dual coil fuel shut off solenoid so I can see what info I can glean from its installation to help DJ54? Dave M7040

I did what you suggested and got into the site. I found the fuel shut off solenoid and a diode. Both were illustrations or sketches so of little help except to confirm the solenoid has 3 wires and the diode is present. Thinking Ago did not invent the fuel shut off solenoid I started to look...

John Look at this wiring schematic for a B2 Kubota. I know it is not your tractor but the diode #11 is on all sorts of riding mowers and farm tractors of all sizes. The diode is on tractors now because of the electronic stuff on them. When a solenoid is powered up and then has the power...

John Is your copy of the manual electonic? If so first try emailing it to me. david.petepiece@sympatico.ca Dave M7040

Sir I am pasting a post I made intended for you to see at the bottom of this one. The more I read your two posts the more confused I become. Exactly what solenoid are you talking about? The starter and if so is it integral with the starter or apart from the starter. Why did you think it was...

I tried finding info on your tractor such as parts diagram, but the best I could do was to find an AGCO web site that needs an owner to go to their dealer and request login name and password so you can look for parts. My suggestion is for you to do that if you can. I really dont know where you...

When I bought my new M7040 with cab and FEL in Oct of 2012, I wanted R4 or industrial tires to minimize damage on lawns etc. rather than the R1 radials on it at the dealer. Dealer had to order tires and wheels from Kubota as the sizes and thus wheels were different than the R1 for some reason...

Over the years many forum members have been seeking ways to avoid their blower digging into gravel, lawns and other soft surfaces where they need to blow. I came across the option of hydraulic controlled wheels to keep the blower off the ground by Pronovost, a very innovative Canadian...

I am having to remove the fan/impeller on my farm tractor size snow blower. Manufacturer said some heating of the hub will be needed to get it to release from the gear box splined shaft. Years ago when I was doing a lot of work I had a heavy duty torch set made by Purox. That set eventually...

I have had a close call with a squirrel nest built around my turbocharger. I would feel better having a fire extinguisher handy but finding a place to mount one in the cab seems next to impossible. Anyone have any suggestions? Dave M7040

I have some info owner's of M7040 with FEL may find interesting. I was having trouble lifting my large heavy snow blower (when the blower was covered in snow and ice) on the 3pt hitch in spite of using the lift arm holes which provide the greatest strength. My shop manual provided instructions...

Thought I should share this close call with others. I have a new M7040 with cab and FEL. Rear tires are ballasted. I was moving fill from my farm to my brother's home a short distance down a paved road. I wanted to pile the fill on some tarps to make clean up easier. The tarps are heavy. The...

I have a M7040 with ultra cab about 2 yrs old. One of the yellow signal lights on the rear fender had a bulb burn out. When I removed the lens to replace the bulb I could not tell if there was a gasket between the lens and the lamp housing. Pieces of a small round rubber like material came out...

M7040 Kubota, 220 hrs, with two remote valves. In cold weather the valve levers cannot be moved until the tractor cab gets quite warm. Dealer replaced one cable when tractor was new because of this problem but it did not fix problem for long. When I remove the cables from the valve levers I can...

I used the following part from Princess Auto on an old tractor I had. For $25 it is worth trying.. Fuel Level Sending Unit | Princess Auto You might have to buy a gauge to go with it but it will all be quite cheap. Perhaps you can cannibalize some parts from the sender to repair yours. There is...

I had a Nuffield 465 for 40+ years which I did a lot of work on to keep in top operating condition although appearances were not a concern. Ill health finally forced me to sell it and buy an new Kubota but I still have warm feelings for the old girl. The new owner is a serious farmer and is...

My M7040 has 130 hrs now. It is parked in an open shed. Last weekend we had a late season snow fall and I was blowing snow. The tractor was working hard and suddenly I was smelling something burning. I shut it off and jumped out to look but could not see anything wrong. I could not open the hood...

I came across this old photo from a project I managed a few years ago. I needed to do work on the head of a well which was located in the closed courtyard of a high school. When the school was first built the well was just in a field beside the school but over the years, as additions were built...

I have a new M7040 with FEL and cab which came with industrial tires. The front tires are 12.5 x 20 MITAS which is a size not shown in my owner's manual. The tire sidewall has a cautionary label about only qualified people servicing the tire but there is not a max pressure shown to use to seat...

It has snowed and I am getting to use my new M7040 under slippery conditions. The literature says it has a limited slip front axle but at times one front wheel just spins with the tractor stationary as both back wheels are also slipping. Tractor has 15 hrs on it. Can anyone advise what a normal...
