2240 Hydraulics Revisited

[Steve in IL]

I posted a while back about our 2240 having some issues with the hydraulics - While mowing, the power steering and 3 point would stop working... Shut off everything... No leaks... Restart, all acted well. Happened twice. Tried diagnosing yesterday by just driving around a bit. Nothing happened, other than I noticed that the 3 point is not raising quite as far as it used to. It rises to perhaps about 3 inches below where I would expect.

Any thoughts on what to look for before I tear into it? The tractor has the 2 speed powershift (rebuilt 100 or so hours ago), and the independent PTO.

Thanks, Steve

Is the tractor low on trans oil? That tractor requires the trans oil checked with engine running at low idle rpm.

3 pt not raising high enough could be as simple as an adjustment to 3pt control linkage. Where is L/D lever under seat setting? If not in "min or D" I suggest to place it there. Hyd's stop functioning could be caused from foreign material getting into stroke control valve seating area in front hyd pump. If your hyd pump has a de-stroking screw(item 4 in link) Im suggest to turn DS screw clockwise then counter clock wise while engine is operating at idle speed. How many hrs of use since hyd filter was changed & suction screen checked/cleaned? https://partscatalog.deere.com/jdrc/sidebyside/equipment/59573/referrer/navigation/pgId/251435
