Transmission Gear Oil
Check the transmission gear oil after every 30 hours of operation
or whenever you notice any oil leak. Operating the tiller when
the transmission is low on oil can result in severe damage.
To Check the Transmission Gear Oil Level:
Check the gear oil level when the transmission is cool. Gear
oil will expand in warm operating temperatures and this
expansion will provide an incorrect oil level reading.
With the tiller on level ground, pull the Depth Regulator
Lever back and then slide it to the second notch from the
top.
Remove the oil level check plug on the left-side of the
transmission. (Due to dried paint on the plug threads, it
may require some force to remove the plug the first time.)
See Fig. 6-1. The gear oil level is correct if oil starts to flow
out of the hole as the plug is removed. If so, securely
reinstall the plug.
If oil does not flow from the check hole, add oil as follows:
NOTE: Do not use automatic transmission fluid or motor oil
in the transmission.
Clean the area around the fill hole and unscrew the
gear oil fill plug.
If adding only a few ounces of gear oil, use API
rated GL-4 or GL-5 gear oil having a viscosity of
SAE 140, SAE 85W-140 or SAE 80W-90. If refilling an
empty transmission, use only GL-4 gear oil having a
viscosity of SAE 85W-140 or SAE 140.
Using a clean funnel, slowly add gear oil until it flows
from the gear oil level check hole.
Reinstall and tighten securely the gear oil fill plug.

Lubrication
Proper lubrication of the tiller is an essential part of your
maintenance program. After every 10 operating hours, oil or
grease the lubrication points shown in Fig. 6-2 as described
below. Use a good quality lubricating oil (#30 weight engine oil is
suitable) and a good quality general purpose grease (grease that
has a metal lubricant is preferred, if available).
Remove the wheels, clean the wheel shaft and apply a thin
coating of grease to the shaft.
Grease the back, front and sides of the depth regulator
lever.
Remove the tines, clean the tine shafts and inspect for rust,
rough spots or burrs (especially around holes). File or sand
smooth and coat the ends of the shaft with grease.
Oil the threads on the handlebar height adjustment screw.
Oil the threads on the handlebar attaching screws.
