I have a late model TO 35 with 4 cyl standard diesel, it doesnt have a SN buts its late model.

I have seen some reference to the older TO 20 about the lift arms but not if the 35 is the same troubleshooting or not.

I have live PTO and can lift the 3 point with out the PTO being engaged.

The problem is the 3 point worked fine then I added a Ballast (rock box) to help offset the weight of the loader and now it doesnt lift. The 3 point just vibrates and once and awhile it will lift if throttle is maxed.

The Mineral oil need to be replaced as it got water in it. I seen reference to pulling the inspection plate with the dipstick off to inspect inside. If you drain the oil to do this will the pump be able to still work?

any help is appreciated

Tony, Are you in Michigan? If so where are you? I also have a TO35. The fine gentlemen here have helped me iron out lots of issues as I brought this unit back to life. I am in the thumb, 11 miles north of Port Huron. Drop me a line if you are around my area!

It is quite a different system on the 35. Revving the engine is not the answer and will only damage the Pump if it has water in it as you say. Don't run it without oil, ever. It does not need the PTO to be engaged on a 35. It could just be the adjustment on the Top Link attachment point, this is the automatic draft control and the weight will be pulling on it. Are you lifting the rear linkage with the position control lever or the Draft lever, if you use the draft lever it could do what you are saying when there is a weight on the back as it is moving the Control Valve, so you have to operate it differently. Do you know the correct way to operate these hydraulics or not? if not and you want the correct information, email me with your email address so that I can send you the info. If you tell me what you are doing with the levers and if your loader has a seperate Pump or not or it it using the tractor Pump inside under the seat. I can tell you how to operate it....John

I have the draft pulled all the way back in quick response and only use the lift lever to move the 3 point. The 3 point was working before but I only tested it with a 200 pound person standing on the arms.

The tractor has a crank pulley mounted hydro pump.

The weight is a 55 gallon drum cut in half and filled with road gravel. When the arms are all the way down the barrel is about 6 inches off the ground.

I will change the oil GL 1 this week, I hear people of making adjustment and changing o rings I just want to make sure. I dont see any adjustments were the top link connects or you talking about the top link itself. It doesnt feel like its binding on the top link as I can easily pull the pin with out much effort.

Tony, I have to agree with Dave. My TO35 had a yellowish, thin fluid in it when I purchased it, I suspect it was trans/hydraulic fluid for newer tractors. The lift arms shuddered when lifting an implement and quickly sank all the way down as soon as you stepped on the clutch or shut the tractor off. I drained it thoroughly and replaced with GL1 90w mineral oil. Now the lift arms stay up when you press the clutch and have no shudder. They seem to lift faster as well. If you want to remove the inspection plate, you can do so without draining the transmission, you should not lose much fluid. Do not run the tractor without fluid in the transmission, the pump will quickly go dry and become damaged. For certain do not put your hands inside the inspection plate hole while the tractor is running. Changing that fluid is the next thing to try, since you're going to have to do it anyway.

The oil is real thin and diluted with water and I planned on Replacing it with GL 1 mineral oil. I want to drain and fill it once. Just need to make sure I get everything checked out like O rings, gaskets, valve and springs inspection/adjustment.

Is there a filter and where is it at? Thanks again.

There wasn"t a filter on the original Pump on the TO35 but it could have had a later Pump fitted, in that case the filter would be just inside the left side inspection cover, remove this plate with the PTO lever fitted and it is straight in front of you. It should be locked in place with some wire, remove the wire and unscrew. You can also use a Multi-grade oil in the Transmission like 15W/40, usually this is easier to obtain than the GL1-90W....John

Start your trouble shooting by draining out the water laden oil. Flush and clean the cavity of any sludge.Then refill it with M1103 avalible from your nearest massey ferguson dealer,it will require approx.8 US gallons. After 6 gallons are in pour slowly and give the oil time to settle,verify oil level with your dipstick DO NOT OVER FILL. Do not attempt to use your system untill you have comepleted this.
