Attempted to feed round bales today, no luck. No hydraulics at all. Ran the engine for about 1/2 hour and put turbo heater on mcv and ran it under tractor for awhile. Still no luck. I have no place that I can get this in and warm the whole thing up. Where do you think the ice would be. Should it thaw just by driving it around because I can't get it to. The fluid is up and doesn't really look cloudy. Fluid and filter aren't very old.

Mine used to do that every now and then, the first time it was -40 and I layed outside and changed the filter and drained the fluid and warmed the fluid by the wood stove, didn't help, turns out it was the relief valve sticking, it's on the lower right side of the seat toward the front, think it is a 3/4 inch plug, take it out and warm it up.

There is a little plug on the lower front of the valve body on the left side of the ta housing with the motor off remove the plug.start the motor. Shut the motor off as soon as the oil squirts out. Put plug back in. This is only a quick fix because the pump will have to be replaced at some future time.

I'm in west central Wisconsin and temps around 10 to 15. I'm not sure if pto runs, never tried it. Now I'll probably have to plug it in again to start it. Its been sitting to long. I'll try Saturday and start a new post.

Everyone has mentioned water in the oil, but since both pumps are dead and if they are quiet, no squealing starving for oil, could well be the pto drive gear or clutch splines have let go. Does the PTO run when you turn it on? If it does'nt good chance your going to have to split it and find the mechanical problem.

I agree with Scott,

Unless you've had 'er swimmin' in the river, something else is wrong; especially if you just changed oil and the filter.

Does that PTO work?

I changed the oil and filter in August so it isn't overdue and that included everything. 17 gallons worth. I will have to try tarping it and heating I guess then drain water. In answer to Chucks question neither pump is working, I have a loader on it and that doesn't move either.

Now since we are doing tractor repair on the key board here and i can not see the tractor or check anything myself there is one other posibility here that she has a woren pto input and a woren pressure plate drive spline and these will drop kick ya with no noise to speak of So to elimate that check and make sure that the PTO still works if that is not working then nothing else will work as it is stripped out and will need to be split and have the PTO input shaft replaced along with a new pressure plate . This is not and uncommon problem .

K B has it about wright ya got water contamated hyd fluid , pull the filter and replace while your at it buy several . Now as far as thawen out this old girl it is going to take a bunch so here is and old trucker trick if ya got a good old tarp now one of the blue plastic one wrap the tractor in like a tent and put the heat to her and it will take a good while to warm the old girkl up as there is a bunch of COLD IRON to warm also after it thaws out before ya start her get down under her and crack the three plus on the range trans and the rear end and see if ya can drain what ever water ya can out now don't pull the plugs all the way just loosen them enough to drip and let them drip till ya got oil comming out . Now becareful as we don't want ya to catch the old girl on fire . We went thru this with a good friend and neighbor several years ago when temps dropped to way below 0 and he needed to grind feed i got one of mine going and we pulled his in the shop as his was so full of water that it had the bull gears frozen solid took two days in a heated shop with the pulgs pulled before she started to drain.

Hi, Does your hitch work? Sometimes the front pump for the power steering, brakes, and torque can lose its prime. If it is just that one I may be able to help. Good Luck, Chuck

Put your heater on the filter housing, or try a new filter. Hopefully it"s just ice crystals plugging the filter. Running the engine was not a good thing to do, as the pumps were being starved. It doesn"t take much to get enough moisture into the oil that operation is effected. Normal condensation will build up, and rainwater/melting snow will find it"s way in if the tractor is parked outside. Yearly fluid changes are recommended, but not real practical with the price of oil these days. It sounds like you"re due now, and try to change it at least every two years. Drain the oil when the transmission is totally warmed up. There are five drain plugs. Three are in center of the bottom, front, middle, and rear. The other two are at the very bottom of each final drive. The final drives are seperate from the transmission on 06 and early 56 series tractors that have not been updated, so you"ll need to fill them through the check plug located about 3/8 of the way up the back side of each final drive.
