Used my tractor yesterday and everything worked fine, came out this morning to move some manure and no hydraulics either to the loader or to steering, was colder this morning, but let the tractor warm up. Any Ideas?

Do you have water in your hydraulic oil? Ice formed around the pick up... Would be my first guess.

First thing I would do it to pull one of the drain plugs and see if there was ice on bottom.


Is it an 8 speed or powershift? Does the steering work?

It's an 8 speed and no the power steering did not work either. Thanks

If it were mine, I would try to limp it into a heated shop to thaw, then drain the oil, change the filter. With the loader and no steering that may not be an option for you. A torpedo heater underneath for a few hours might thaw it out enough to get it drained, it might catch it on fire too!!!

Thanks RG, kind of guessed that was the solution, had a good chuckle about the torpedo heater. Thanks again. Bob

Throw a tarp over the tractor to somewhat contain your heat. Then carefully position the torpedo heater such that it will not catch the tarp or the tractor on fire.

Having the tarp to contain your heat will greatly help but you still likely looking at 2-3 hours or so to get everything thawed.

Thanks Again RG, changed filter and fluid, warmed the fluid to 80 degrees and it worked like a dream. Hydraulics are much quicker now. Thanks Bob
