1532 Hyrostatic problem/question.

jmarx82 · Feb 1, 2015

I see what your saying TSO, and I see that might be my problem going forward, but when trying to back up the hill I am starting from a dead stop and the tractor won't budge until the HST pedal is pretty much all the way down. I keep up on my tire pressures, so hopefully the rims are not spinning. I'll touch base with the dealer tomorrow. I hate to drag the tractor all the way down there, because its a 2 hour drive. I am sure I will be out plowing today with this snow were supposed to get. Thanks for the reply's.

How does the tractor react when you are in LOW range?

In low the tractor does good, but it is a real pain to plow snow in low. I ran this same plow on my Kubota B2920 without issues in Med.

Yep, it should work well in MED on the Massey too.. I am guessing the hydro relief valve is opening at too low of a pressure. If you push the loader up against a big tree or other immovable object, will it spin all the tires in LOW?. Does it even attempt to spin the tires in MED? at least on soft ground or gravel?

The engine should bog down noticeably and lose RPM's. even in MED.

Well we have plenty of snow and ice right now. In MED it will not spin the tires if I put the plow into a pile and go forward. It will lug the engine. In LOW it will spin the tires.

OK. I am sticking with my analysis of Hydrostat relief pressure set a bit too low. That's my story and I am sticking to it. If there is a hill you cannot climb in MED range, then that is a problem.

I found TSO's thread about adjusting the relief psi on the loader. Now I just need to find the relief valve for the HST and where to test it.

I'm wondering if it's a linkage issue. My tractor is a hydrostat with a three speed. I can never spin the tires in medium and only will about half the time and low. In my case it seems to have a lot to do with traction. My Tractor is quite heavy and seems to hook up very well. The reason I say linkage is because you seem to only have a real problem in reverse. it certainly could be improperly set Hydro relief but also sounds like it could be too tall of a mid range gear to do what you are trying to do. Question on the times that you are able to spin your tires in low do you have a good traction situation and proper ballast-or is it running light on low traction surface when you are able to spin in low?

If you're linkage is improperly set or adjusted I think that it could cause a lot of the problems that you are describing. That and over pushing on the forward Hydro under load in higher gear.

One more thing the rpm's at which you run play a huge role. Are you running at a high enough rpm when doing these tasks. If you can lug your engine at proper RPMs then it's most likely NOT a Hydro relief problem.
