Couple of quick checks you could do. Unhook the
return line from the foot n inch valve and drive
tractor and try stall test. If fluid comes out of
that return line the valve is leaking or not
adjusted properly. Pedal must not contact the
platform when fully back. They do break the spring
inside foot n inch valve quite often also, same
symptom. Other test, little more involved. Find
two steel caps to fit the two lines leading from
top of trans multi valve , cap off those fittings,
and give it a try CAUTION, you will have no
control with the foot n inch pedal when doing
this, only the speed ratio lever. If it still
won't stall out the problem is definetely inside
and not any of the control valves. You do have two
capsules in the drive control valve that can cause
problem and this test will eliminate those during
test.
