SECTION 3 - LUBRICATION AND MAINTENANCE
3-56
EVERY 1500 HOURS OR YEARLY
With either PTO equipped transmission, the PTO
drop box is pressure lubricated by the
transmission lube system. Drain the drop box at
the rear of the tractor by removing the hose, 1,
from the bottom of the box and allow the oil to
drain out completely. Replace the hose and
tighten the hose fitting.
Refill the transmission with new oil through the fill
tube, 2, to the proper level as indicated by the
sight gauge, 3, (or dipstick on powershift units).
See “Checking the Transmission Oil Level”
(Operation 10). Start the tractor at low idle and
allow it to run for two minutes to refill the PTO
clutch housing and rear PTO drop box. Shut the
tractor off and recheck the transmission level.
Add additional transmission oil as necessary.
NOTE: The PTO drop box located on the rear
of the transmission does not require draining
during transmission oil changing.
