TRANSMISSION REMOVAL/REPLACEMENT
Should your transmission require removal for service or
replacement, it should be purged after reinstallation and
before operating the tractor. See “PURGE TRANS MIS SION”
in the Operation section of this manual.
The rear wheels must lock and skid when you try to manually
push the tractor forward. If the rear wheels rotate, the brake
needs to be adjusted or the pads need to be replaced.
TO ADJUST BRAKE
• Depress clutch/brake pedal all the way down and en-
gage parking brake.
• Measure distance between brake operating arm and
nut “A” on brake rod.
• If distance is other than 1-9/16", loosen jam nut and
turn nut “A” until distance becomes 1-9/16". Retighten
jam nut against nut “A”.
• Engage transmission by placing freewheel control in
“trans mis sion engaged” position.
• Road test tractor for proper stopping distance as stated
above. Readjust if nec es sary. If stopping distance is
still greater than fi ve (5) feet in high est gear, further
main te nance is nec es sary. Replace brake pads or
contact a qualifi ed service center.
