Dont know what 35 is, but i've lost drive and had code 64 and 72. Dont know what they ment, but restored drive by either turning tractor off and on repeatedly, or by leaving the tractor idling for 10 muinutes or so. This lets the control unit sort itself out. Remember the system also shows clutch problems, it may be a job for a new holland dealer, with a computer and some replacement parts. sorry i can't be more help.
