Ok guys need some further guidance here. I had top clover off and pump out completely cleaned the case put new o ring and backup washer
on piston piston and cylinder bore were not perfect but did not look bad, no major scores or anything. Did not do anything to the pump except
to put in a new relief valve. Smashed my finger real good putting the top cover back on, lesson learned. Ok here is what it is doing. Lift will
raise a 5 foot bush hog all the a up when tractor is setting still, but not while moving. Also leaks right down when clutch is pushed or pto is off.
Took side cover off to check for leaks and saw nothing from top and just a few, maybe half a dozen,bubbles from where the relief valve is.
When' nothing is attached to lift arms, they start to lift when quadrant lever is moved a little from bottom position and continue to raise as lever
is moved up. But when bush hog is attached quadrant lever must be almost to the top before any movement occurs, then when lever is moved
about 2 inches to the lower position, bush hog is on the ground. Only works in the top 2 inches. Can't understand why lift will raise heavy load
while setting still, even at low engine speed, but will not lift unit very much while moving. Eventually it will raise enough to clear ground. Stop
tractor and it raises right up. Could this still be a pump issue? Sorry for the long narrative but had to explain what is going on. Thanks.
