TRANSMISSION
The transmission drives the two front wheels.
Check the oil level after every 25 hours of
operation by looking at the reservoir mounted on
top of the transmission. The cold oil level should
be 0 to 0.25 in (0 to 5 mm) above the cold mark.
Use straight SAE 20-weight, API class SF engine
oil.

Proper cooling is essential to both performance
and life of the transmission. Keep the fan and
cooling fins clean.
ATTENTION! Cleaning the transmission with
high pressure water spray or live steam may
allow water to enter the reservoir. A few drops
of water in the system will result in loss of oil,
and loss of power.
If contaminants are observed on the reservoir
screen, remove, wash and clean it. If the reservoir
screen has been pierced, internal failure may
occur. The damaged reservoir should be
replaced. If the transmission oil color has changed
to black or milky, overheating and/or water
contamination is indicated. The oil should be
drained and replaced with new oil.
NOTE: The threads connecting the plastic
reservoir to the aluminum cover are “left hand.”
To drain transmission oil, first blow all dirt from
the reservoir and vent plug. Remove the drain
plug in the bottom of the transmission and the
vent plug in the top. Allow the transmission to
drain completely, replace the lower plug, and
refill the transmission through reservoir with new
SAE 20-weight engine oil. Rotate input and
output shafts to purge any air trapped in the unit
and fill until oil overflows the vent plug opening.
Replace the vent plug and fill the reservoir to the
“cold” mark.
