I've recently purchased a '99 TC33D with 1050 hrs. on it. Tonight I noticed that the wheel is extremely hard to turn when not moving. It's fine when the wheels are straight and I turn either right or left a little, but when I get to the 45 degree point is when it gets bad. It's not cold here yet so that's not the problem. Does anyone have any info on this? Is there a seperate P.S. pump? The loader hydraulics seemed fine tonight but I didn't use it that much.

Might be normal if it has turf tires with low pressures and no weight on the 3ph--especially if there was a load in the bucket. You might say what the circumstances were and somebody who knows the tractor can say if it sounds normal or not. The description is basically how my Ford 1710 PS is and I've never been certain if it's normal for a puny mid-80's PS design or if it's gotten gimpy over the years.
TC's are sort of cousins of my 1710. My PS steering runs from a priority valve on the main pump. Separate PS pumps are better and I don't know if 17 or 1920's, which may be more like your TC, had separate pumps. You can tell if you look at the pump. If there's a small steel line coming off the lower part of the pump above the outlet pipe then it has a priority valve. The small steel line goes to the steering sector. This type PS isn't particularly strong and needs help from ballast. ....

I just talked to the service tech, he said to check the pressure and adjust the pressure relief valve. There is a seperate pump for it and said they have not had one that went bad yet. He said it might be alright to adjust it by about a 1/4 turn since I don't have a hydraulic pressure gauge. ....

Sounds like reasonably good advice. Gauges are cheap but the special fitting needed to pressure my PS is very expensive. I probably have low pressure as well but the problems isn't so bad to cause me to fabricate a fitting and the tractor hasn't been back to the dealer. There is the small risk that the pressure is OK but the steering is binding and increasing the pressure would just compensate for something that needs to be replaced.
In theory that possibility could be checked by listening to the engine while the turning the steering while the tractor is sitting. You should hear the engine throttle up a bit to carry the PS load. If the front is lifted with the loader and the steering tried again the engine should load up less unless the steering is binding. But as I say, that's theory.
If your PS line goes into the sector like my 1710 rather than to cylinders there may be a steering adjustment issue. My 1710 owner's manual describes the adjustment but doesn't mention that the engine is support to be running. The repair manual says the engine should be running and the repair manual is right. ....
