I bought an early model JD 2640 for mowing. When I got it home and put an implement on the 3 point, the arms would not lift the load. They do go up without a load on them. The place I bought it from said to bring it back because the pump was most likely bad, and I took it back.
I sort of fell in love with the tractor. Lot's of power and the transmission had lots of speeds (hi-lo). Power steering was awesome and generally just a nice tractor. It is the 2640 with the lower, wide rear tires like a utility tractor.
Everything seemed to just work really well on the tractor.
Before I took it back, I checked the suction screen and changed the hyd filter, with no change in the lift.
I've been reading that the hi-lo might be stealing flow from the 3 point via an internal leak, and some other internal disasters that I do not want to assume. Is this a fatal issue with this tractor or a repairable issue with my limited mechanical experience?
