Tractor PTO Gearbox Lubrication
Checking Gearbox Oil Level
The tractor PTO gearbox is permanently lubricated
(oil filled) and sealed requiring no scheduled lubrica-
tion. However, the gearbox oil seals should be
checked every 25 hours for indication of oil leaks. If
evidence of an oil leak is noted, replace the oil seal
and relubricate the gearbox. The gearbox can be
drained by removing the plug on the gearbox cover.
Replace plug and refill gearbox using 5 fl. oz. (15cl)
of SAE E.P. (Extreme Pressure) 90W oil.
With the deck removed, the tractor unit may need to
be tilted forward (resting on deck support arms) for
positioning purposes, to add oil into the PTO gear-
box.

Transaxle Lubrication
•
The transaxle oil lubrication is SAE 20W-50 en-
gine oil.
•
Inspect both transaxle cases after every 100
hours of operation for visible leaks. If a leak is de-
tected, the oil level should be checked through the
breather port on top of the transaxle. Using a clean
rod, measure the oil level by placing the rod in the fill
port and bottoming out the rod on the bottom of the
case. Remove the rod and measure the oil level on
the rod. It should measure 4 to 4-1/4 in. (10 to 10.75
cm) total depth of oil. DO NOT overfill.
Steering Linkage and PTO Linkage Lubrication
The steering and PTO linkage are located at the rear
of the tractor below the body. The grease and oil
points should be lubricated every 25 hours.

CAUTION
Do not leave the mower in this position for
an extended period of time to prevent oil
from draining into the heads and causing
possible engine damage.
