TIM S. hello, i'm the JD guy from va. i emailed you some time ago complimenting your 60 crawler & 60 FWD. i am
working with a 8640 tractor, won't move. the farmer used it this morn discing, everything a-ok. came back after
lunch, tractor won't move. i've got the tech manual here at home studying. i checked pressure at a port on
traction valve, i thought was clutch press. but it turns out after study it was pto brake port. running 170 lbs.
tractor is out on the farm.so i didnot have much time & did'nt recollect the checkout procedures, as i have worked
with a lot of these over 30 years ago. the top open drive shaft in the hinge area is NOT turning, and you can
shift thru the gears with clutch pedal out and NO grinding. ANY THOUGHTS, THANKS. hydralics work ok
