hydraulics

Hello - new to this forum. I ran this by a longtime member first and he suggested I post to the group. It got a little long in the tooth. Sorry about that. I tried to put the main questions I have first...the fluff follows. What is everyone's experience with the Pilot Control Spring Mod, if...

My old (at least 20 years) John Deere 670 Compact Utility Tractor has gotten to where the hydraulics are quite weak. In particular, the Model 60 loader (bucket with tilt and lift) has gotten much weaker than it used to be. I'm wondering how to fix the problem. Is it likely I need a new...

Hello, i am new here. and will admit not super knowledgeable on our old JD 7520. i am here because my dad asked me to check the internet to see if i can find information that might help us figure out the lost steering and clutch in our tractor. this problem showed up last year and after...

I am looking to add a grapple to my FEL and also an actual rear remotes as the single action setup does not really seem to provide any value. My current set up is an adapterplate under the seat driving a dual cylinder dual action valve with the FEL. The valve has power beyond configured...

i'm hoping to find an owner of a JD870 (or 770/970 i believe are the same) who has one of the following: the rear hydraulics package, a backhoe or ideally a front snow plow blade who can tell me which ports JD is using for the output and return lines as we have tried everything. in detail.. our...

I am new to the forum; so don't really know how to participate but here goes. I have own a Branson 3510i for a few years. Bought it used from a friend. Everything worked fine. A couple of days ago the bush hog came all the way to the up position and has stayed there except when the engine is...

I have a 25hp Agtrac tractor. Bought on Marketplace, first mistake... Replace all hoses/lines from Control to FEL... Rebuilt all FEL cylinders. FEL works but is weak. Only lift about 300 lbs. Bought gauge and checked pressure. At fast idle - 800 to 900 psi. At 2000 rpm 1100 psi. The Pump has...

Tractor only has 112 hours on it but 10ys old. I had bucket pointed down with most of the front weight on the ground trying to scrape dirt backwards, heard a "POP" and the control would only move the bucket very slowly the quit all together. I pulled all four cylinders and checked operation with...

I am new to the forum and looking for insight on my Steiner 440. I just purchased my first Steiner tractor and had a question about a noisy hydraulic pump. When the tractor is under a load the hydraulic pump sounds like it is screaming. As soon as I am mowing flat or going down hill it sounds...

Hi folks! I bought a Little Buck loader and now need to plumb it. I had no idea it was complicated! its only 2 cylinders? I have a pump A BDP-10L In fact I have 2 pumps. Sent to me by the little buck guy! I have been told it will take 2 pumps to power the loader? I also have a return tank...

As the title says..... My mower is a Ferris is5000z diesel (yeah, it's an older model). Last fall my crankshaft broke and long story short, I had the mower towed into the shop. They serviced it, but wouldn't touch the motor. I found a local guy to rebuild the motor, which is now working great...

I own a Kubota 7060 that runs 11-12 gpm. I'd like to have the option to run some skid-steer attachments that require a flow closer to 22-25 gpm. Can anyone point me at a recommended product (like a PTO hydraulic pump, or even something that could be mounted permanently, if it exists) for this...

I have a Deere 1050 which I think is about a 1988. Having issues with the Hydraulics and pressure relief. The suction Hose that goes from the spin off filter to the hydraulic line is compressing which is restriction flow. Any Help?? Also had water in the system which I changed the oil and...

I have a JD 4310 EHydro with steering, movement and PTO issues. I have replace the fluid and filter and cleaned the screen. Replaced the manifold on the pump. Lifts work but the three things operated by pump LVA11451 are not working. Is there any way to check to see if the pump is working or...

Has anyone had this issue? The Joystick for the hydraulics is stuck. I am interested to know whether this is a dealer service center only fix or perhaps a possible DIY solution. Thanks!

Stop Error On T4.75, Low Power Steering Pressure / Transmission Pressure 2019 Powerstar 75 Symptoms Day started out with all running good, no apparent problems, then STOP error comes up along with a symbol on the display that closest resembles the low pressure, and steering wheel. However I...

I have a 2706E that has had an ongoing issue with the 3pt hydraulics. Today they stopped working, and I'm looking to see if anyone in here what I need to dig into in order to get them operational again. The FEL and steering work they way they should. There's oil in the site glass. The...

Why want my rear lift arms stay when low RPM?

Hello everyone, working on my JD 2240 today . Putting the bushings in the rock shaft lift arms. Just wondered if any one else has ever done this, and if the new bushings took the play out or if the shaft may need replaced.

Hi - somewhat of a novice here. I have a Mahindra 2310. I had a hydraulic leak on a rubber boot on the right brake rod, and I lost a lot of fluid. I replaced the boot and refilled the hydraulics (about 4 gallons), but the hydraulics aren’t working as they should. Before the repair, I had no...

Hello I'm French and I own a 69' Ford 3000 tractor made in Belgium. I've recently mounted a Quicke 2200E front loader on it. The hydraulic spool valve has a remote joystick. From the beginning, I've been having a weird problem, at idle, the loader works normally but is quite slow (30 sec from...

I would like to share my excellent experience with FitRite Hydraulics (aka Brian Scudder). I have a 2006 Kioti DK45s. It is awesome but that model had a short production run so it is not the most common tractor out there. Making accessories for my tractor is something of an experiment unless the...

Hi so I’ve been browsing the site and have found some information to guide me but I’m still not sure if what I gathered is good for my application. I have a bolens iseki h1502 and I am looking to install remote hydraulics to control a snowplow on the front. I am not sure where to plumb my...

Hi folks, after looking at wood splitters as per this thread: BCS branded wood splitter? I have been wondering if anyone has set up their tractor to run a splitter or other implement that would be freestanding but utilize the PTO via an adaptation to link to the hydraulic pump. Since the pump...

How easy or hard is it to install 2 more hyd ports?.

Did a little work on the tractor today. The older 7320 has metal channel iron pieces you put on the cylinders for safety purposes when working under the loader to keep it from crashing down. The 7340 has a lever on one of the hoses that prevents the loader from coming down. My dealer didn't...

It seems I remember someone from my past who told me when you are done with the tractors hydraulics you should take the load off. Meaning drop them down to where they are not holding up pressures. I almost always (rarely forgetting) to drop the FEL down to the float mode, lower the 3 pt down...

I bought a new MX5400 a few years ago to replace an L4330, and have been fairly happy with the tractor. One thing I have not been impressed with is the lift capacity on the FEL, which has never felt as strong as the 4330. After watching a few vids, I am convinced the relief vale on the...

Hi folks newbie here again. Just finished assembling my new WC-8 Chipper and I need to know how to hookup the hydraulics to the tractor. This is what I have;

I have a YT359 ROPS with two factory hydraulic remotes. I would like to run a 3pt hitch sickle mower (Brush Hog PT5) that has a hydraulic controlled boom and a hydraulic motor driving the sickle. Based on my limited experience with hydraulics, I believe I could run the mower off one of my...

The bucket quit raising but tilt works

Hoping someone can help me, I’ve inherited a 7030 and it has the hydraulic splitter type thing on loader. The ports have been blinded as aux hydraulics never used. I would like to use a grapple attachment through here. Does anyone know if I can use this to control grapple and still have full...

New to forum. Glad to be on board Inherited a Foton (Euroleopard) FT454. Have had no issues. Not sure when was last serviced but have done the oils. Eventually got the hydraulic filter out (obstructed by FEL frame). Dropped 10 or so litres oil. Q1. Is there a dipstick, if there is where is...

I want to connect a 3PL backhoe to an AgKing DQ554... but only have spring-loaded levers for the hydraulic outputs. What am I missing? :( Any hints appreciated. The tractor the backhoe was on has continuous and monetary flow, controlled by levers staying in that position. Each outlet has a...

My friend got a clean little 3038E and he wants me to help him put 3 rear remotes on it. I need help. Who knows what to get and where it connects? What size cylinders for top and tilt? Your experience is appreciated. Thank you

Does anyone know what size control valve I need for a loader on a NH boomer 3050.Thanks for looking,any help would be great

I have water in the hydraulic system. Grey slurry. How to get rid please and how to go about it.

I have a 1998 555e the hoe quit working. The front bucket, and stabilizers work good , the tractor works good, just nothing on the backhoe at all.

I have an L47 TLB and was wondering if there is a simple cost effective way of using the backhoe hydraulic connections to add controls for three point functions like top & tilt when the backhoe is removed.

Fellows, I plan to add three rear remotes to my tractor specifically for a box scraper. Two remotes will control the top and tilt on the tractor, one remote for the cylinder on the scraper that controls the scarifier depth.

After searching for two days I could not find a kit for the 110 TLB. I am somewhat surprised. I suspect there would be a significant demand for such a kit and there doesn’t seem to be much complexity to create one, or so I think. If anyone knows of a kit available please feel free to tell about...

I have just about completed my 300 hour maintenance schedule on my 2022 Branson 2515H. I have noticed a few grease fittings have damage on the BH150 attachment. Would anyone know what the correct grease fitting size would be for the hydraulic pistons? There are (10) straight and (2) 90 degree...

Swapping out the upper cylinder on my Kioti DK6010SE. Curious if those hydraulic hoses sealant or not.

I'm going to convert a light duty truck plow to my tractor (JD 3039R) and I want to make sure I understand how to hook up to the tractor's hydraulics. I am going to use a frame mount, and not loader arm mount - I will remove the loader for the winter season. The plow will be a Fisher Minute...

Hello, I have a 2005 or 4 Terraplane 38hp tractor. Made in China. I've been using this tractor for about 4 years or so (wish I had bought a new one), and have performed a few repairs on the hydraulics (pump ruptured and spilled hydraulic fluid into the engine oil reserves), and now I'm onto my...

Hi Team, Downunder in New Zealand. We have just picked up this little honey for a friend who was struggling with a lifestyle block herself witha few horses and cattle. She has a number of the large round silage bales. The main purpose for this tractor is to lift and feed out the larger size...

We have a newer 115hp Deutz(2019) which has the following configuration as pictured for the rear hydraulics. With three different remote configurations, what should each be used/not used for? For example, we have a Bale Feedout wagon, which has a ram that controls the tilt, and has a...

My old Kubota 7030 remote hydraulics quit working after a couple of hours and it gets warm/hot. I am sure the pump is tired, but I priced them and looked at replacing. I guess not, almost looks like I may have to remove part of the FEL frame. So, we only use this tractor in the summer. Isn't...

Trying to get some hose fittings and don't know what standard is used in Chinese tractors. Specifically the loader hydraulics. Tractor is 18 years old.

I have a Farmtrac 535 that they hydraulics are jerky. I changed the fluid and filter ans cleaned the suction screen/filter by the left foot. It seemed to work better after changed and then I let it set for about a week and it's aherky again. I did not use it a lot after changing the fluid and...

Just have a question on a 2240 John Deere . Could the steering valve assembly leaking cause the independent PTO to grind on engagement. Thanks for any answers.

Anybody knows what, where, how to add the external hydraulic line connectors on an Iseki TX1510? Would it be powerfull enough to activate a hydraulic rotor of a small (80cm) mower blade? I'm considering to add to my tractor this feature below, which is a fence pole mower. But I wonder is my...

Today in the 100° heat my hydraulics gave out and would no longer lift my heaviest implement. The tractor is a New Holland Powerstar 75 and is probably operating at the upper limit of its ability when lifting our Rain-Flo 2670 raised bed mulcher. I immediately suspected a combination of a very...

I have a bobcat 430 excavator SN 563012165. It has been parked under a shed for the past month. Went to move it over the weekend and the only hydraulics that work are the blade, swing boom, and auxiliary. It is showing codes 002-17 & 005-14. I pulled the filter and everything appeared clean...

Background: I have an Iseki TX2160 with a Loader attached that has not been plumbed properly. It has a 2 spool Walvoil SD5 valve block, which has pressure feed taken off from the banjo bolt of the factory pressure line between pump and 3 point linkage forming a Tee. The Tank connection is...

My GC2310 suddenly lost all hydraulics and drive. No FEL, no backhoe, PS.. I was able to limp it into a serviceable location/position because it was in 4WD. Once I took it out of 4WD I had no forward or reverse and have been unable to put it back into 4WD. I thought these only had one...

Greetings I have a 20 year old 4010 compact tractor, reasonably good shape has been serviced regularly. I noticed this past year the FEL doesn't seem as strong, the power steering, once in a great while, will cut out and won't move. Yesterday the FEL just flat quit raising when I was lifting...

I bought my BX2660 with about 250 hrs and now it has about 500. Changed the fluids and filters right after purchase. Always been used and parked in a clean environment. It was never what I would call fast, but now, it seems that the ground speed is only about 3mph. Last winter, it seemed...

I have a 17-year-old Huskee 22-ton log splitter. Control valve broke at handle connection to valve body. Have ordered replacement control valve. My question is do I need to bleed air from system after installing new valve, and if so, how?

I have a diesel MF 135 with no remote hydraulics. I would like to be able to operate a cylinder on a hydraulic box blade. this seems like a light load for hydraulics vs. a front end loader. my question is, will someone recommend a vendor for the conversion kit? the kits i have seen on the...

Hey everyone, looking for some help understanding the hydraulic arrangement on my TN75DA. Tractor currently has 2 Mid-Mount valves for the FEL that are controlled via joy stick and 2 rear remotes that are controlled via two separate levers (both are dual action, top valve has float). My...

There is an update to the first three posts now: post #18 12/7/24. How Massey Ferguson GC 1723 & 1725 hydraulics are plumbed - part 1 A lot of this should be applicable to other GC model tractors. Also, as I describe, I am new to all this so please point out any errors. Sorry, very long post...

Long post, but bear with me, I want to add rear remotes to my Kubota LX2610. Yes, I have done some research and think I have the right solution, but want to run it by folks before I do. Important to note that I already have both a backhoe and a 3rd function valve installed. The backhoe is e...

Just picked up a 3 point splitter that I'm going to use on my Kubota BX25. I know, I know, it's going to be slow etc...I don;t do much splitting so not having a small engine sitting idle for long periods of time are the major pro to the purchase. I picked it up used(looks like it's hardly been...

My tractor sat for a couple of months. When I went to use it, it has no power to the front bucket. I can raise an lower it but only if its unloaded. 200 pounds in the bucket and I can't raise it. I s there a relief valve that could be passing fluid?

Hey everyone, I picked up this 2030 at an auction recently and I have a question about the rear remotes. Looking at what is on the tractor and comparing with the few pictures I can find online, there are controls for these remotes, correct? If you look at the pictures, the lines run straight to...

Hello, I have Question pertaining to the YM276D I am wanting to install some hydraulic quick couplers to attach a 3 point backhoe, I know there are potentially 2 options one being cutting the high pressure line and second using the in and out ports on the hydraulic block under the seat...

I have an older machine amd cannot find a diagram to tell me what these lines are for and the name of the balve they are attached to. And if connection are spring loaded etc. they are leaking and i need to change the hoses or valve or both or maybe just O rings. Any help would ne appreciated...

I'm looking at getting a newer tractor with front end loader and have some questions about the NH TN 40. My 4000 Ford has a very weak hydraulics system for the loader and am looking for a much better hydraulics system. I have run Kubotas and know they have a very strong hydraulics system and am...

Just purchased a used Westendorf loader to mount on my NH2120. The NH has an existing 2 spool remote control assembly on it (diagram attached). 3 lines run in to the valve assembly and 4 lines run out to the implement. The Westendorf has an 2 lever control mounted to the loader with 2...

Hello. Looking for advice on what to buy to add remote hydraulics to the rear of my Ford 4610LCG to lift/lower the decks on a batwing mower. Needs to have a float position. Thank you in advance!

I was bush hogging. Went to raise my bucket and had no hydraulics. Neither bucket or 3 point lift operate. No warning no signs of leak. New to me tractor. Need help.

Anyone try one of these kits? Seems like a good option for the money. Factory kit for my 3320 is triple the price with a lot of install time. https://www.tractorinnovations.com/johndeere

This tractor I built about 8 years ago. I have a question about how to drive 4 hydraulic motors on my mini homemade 4 wheel drive articulated tractor. Each wheel has it own hydraulic motor on it and they are driven by a hydrostatic drive unit. I have a geared flow divider that supplies fluid to...

Already have 1 rear valve. Wont be using it much. Any shortcuts to getting hydraulic hoses from front to rear? By shortcut i mean ready to go...or will i need to custom make and give every detail/angles/fittings?

Hello all, first post. I just bought a 2006 Massey Ferguson 1547 Shuttle shift, with 740hrs. And I am good with all of the functions and operations. BUT, I am hoping that someone could give me advice (and hopefully part numbers ?) So I can plumb in Auxiliary Hydraulics, likely one set of...

I've got a Ford 5030 shuttle shift that is having an issue with the hydraulics I can't seem to figure out. The transmission shifts great, and the power steering works tolerably. The loader and 3-point hydraulic are very slow and jerky. The loader runs off the rear remotes supplied by the engine...

I bought a front loader (used) for my Zetor 7245. I am trying to understand how it functions as the system is not straightforward. There are four valves, three of one type and a fourth that's different, that I would like to understand what they are for. I drew a (crude) schematics based on...

so i am pretty sure I left the rear implement in the up position last time I parked the tractor for a week or so. when I got in today I found the lever for 3pt lift all the way forward (which I never do). so I thought that was strange. but I started it up. and immediately found the 3pt lift to...

I have a Yanmar US35D and when the guy I bought it from installed the loader he cut the line from the pump, run hoses to the loader control valve, and then to the back of the tractor as it would normally go. I'm now needing some rear remotes and would like a 3rd function for the loader...

I have a Mahindra 5145. This is the first Mahindra i have ever owned. I have noticed when working with the bucket loader or grapple the hydraulics seem to run slow. Raising curling or opening and closing the grapple clamps. Is there any adjustment on the flow speed of the fluid?

My 2nd time out after the unit was returned from the dealer following a rebuild of the hydraulic system (new valves and pump all warranty work). I was using the front loader to scoop wood chips and lost pressure on my bucket curl. Could hear a hiss when trying to adjust curl and immediately...

I have a new MF 1840M that i had them install rear hydraulics to run a wood splitter. The lever has to be held open to run the fluid to the splitter to run it. Is there a way to hold the lever open. It doesn't have a lock built into it. Is there some after market lock or catch that can be...

Please help! I am clueless about rear remote hydraulics as I recently got my first diesel tractor with a loader and rear remote hookups. The tractor is a Ford 5610S. I can't even tell you who the manufacturer of the pump is, what kind of pump it is or what kind of hook ups. I have done some...

I recently purchased an LS XJ2025 with ~400 hours on it. After a few hours of test-driving around my property, I find that I now have a lot of trouble raising the 3PH (it has a 4ft tiller installed on it). When I have the tractor at high RPMs (up to 2700), I cannot find a way to raise the 3PH at...

I have a CS2220 with FEL, purchased new this year, which is exhibiting odd FEL hydraulic behavior. When I raise the loader (even without a load) it will slowly succumb to gravity - both bucket tilt and main arm - with the bucket tilt dropping faster than the main arm. There are no hydraulic...

Hello all, I'm new to tractors and hydraulics as a whole. I have experience with most other things though. Yesterday the left cylinder piston on our front loader snapped in half. Of course the replacement part is about $1200 that we don't have right now. I really want to use the brush hog this...

We have a TYM T1054 tractor. Having some issues with hydraulics. This thing has the Bosch control in the cab and we have been learning more and more about it. The control is throwing a code 22 that means no communication from the potentiometer. This controls the and tells the brain where the 3...

I have a John Deere 4100(gear) with a 410 loader. I want to replace the seals on the hydraulic cylinders. My problem is that the serial number of the FEL is WO0410X014991 but the parts listing from Deere doesn’t seem to match up. I would like to replace all the seals on the loader since it is...

I have connected a spool valve to the pressure port and return port on the manifold of my Ford 1320. (1988 with 800 hours) This diverter is on the RHS, just a little below the hydraulic pump. The spool valve is open centre. According to the user manual, I have rotated the control screw to...

Last week i bought a Yanmar YM14 mower. Cool tractor with a diesel engine, that will save fuel costs.;) The idea is that the Yanmar diesel will replace my Ingersoll 3014. There is one problem, the Yanmar mower didnt have hydraulics ! I did a search on the web and i cant find if there hydraulic...

I've had my 1975 DB 995 for 26 years. I have a Loader on it. I was Roto Tilling this AM. After pulling the Hand clutch to engage the PTO, I tilled approx 30 yards and then tried lifting the tiller. It would not come up out of the ground. I switch Hydraulics to LOADER, it would not raise...

I have a Kubota MX5200 with remote hydraulics on the rear. The controls allow me to side shift my flail mower. I want to hook up a Backhoe and I need continues flow of hydraulics to the Backhoe. I was wondering if I can use the remote hydraulics by taking the controls and lock them in a...

I would like to change the hydraulic filter on a 1962 Case 430 with the 188ci Diesel, manual clutch/transmission, manual steering, single control for attachment up/down, I can only read the first two numbers on the Wix filter “31?” The rest are obliterated. Any help would be greatly appreciated!

I need a backhoe. I am looking at skid steers and loader style machines. I am wondering if it is possible to add the aux hydraulics in some way to run a backhoe on a Waldon 4500b?

I'm a first time poster and first time tractor owner. I have searched up and down on the internet and this forum and couldn't find others with my same symptoms, and none of the proposed solutions for similar issues have worked for me. My maintenance experience up until now has been servicing...

My ~35 year old tractor started have an issue with rockshaft/3 pt hitch pulsing ( up and down <5% of travel at a frequency of about 2 times per second when loaded ( chipper attached or me standing on the 3pt hitch) and not moving up or down. I changed the Hydraulic oil, filter and checked...

Hiya I've recently purchased an old Iseki TX2160 and am slowly working through the obvious faults, servicing etc and trying to make sure it's working as it should be (as much as possible for this old machine!). The tractor has both a front loader (I believe it's one from a Kubota) and a backhoe...

I'm not finding much direct comparison between WRLong third functions and OEM kits. I am considering installing it myself (mainly to learn more about maintenance). Both kits are virtually the same price. I'm on a kioti, and the instructions are from what i read - but i care more about...

My 1710 Ford front loader lift has no power. Actually it won't even lift without red lining the tach unless I fully raise the 3 point hitch. Then when the 3 point hitch is raised the front loader goes up whether trying to raise or lower. I have to lower the 3 point slightly to make down work...

Hi all, well I just bought this brand new (in about 1988) Kubota KH41 (similar to a KH36 I think) and I've got a few problems with it. First is the ghastly paint scheme - but I'll live with that for now - its been very rusty, and this paint is on THICK to hide it! So I don't see an easy fix...

New to this site and my 1st post - be gentle :). I have an old Toro 580D (80hp) hydrostatic batwing mower, planning to remove the mower units and add a front-end loader. That phase should not be too difficult - the mower has lift valve for 3 cylinders currently, I'll use them as lift, roll and...

I built a mechanical thumb for my machine but would like to convert it to hydraulic. The Case has "nibbler-breaker" hydraulic lines. I had a hydraulic cylinder I hooked up to test it and it does not retract I believe it is not a gravity return like on a snow plow since it has a return line but...

I have around 600 hrs on the tractor and over time the 3 point arms started to leak down while tractor is running. At first about every 30 seconds the implement would jump back up and gradually over time its happening every few seconds (after tractor is hot). I can turn the valve under the seat...

I have a ck3510se-hc with the 2 rears and would really like to eventually get a top n tilt but need to keep 2 pairs open for my flail mower. I've seen a few videos showing these off but not of anyone actually using them, and not much on the forums...

Hello all. I've got a Ford 1700 with no lift on the 3pt hitch. My grandfather bought it new and I've used it for the last 20 years and has been a great tractor. Anyway, It went from working completely fine one day to a little jittery and then completely stopped working the next. I believe I've...
