Gearbox
The gearbox is almost maintenance-free, but should be
checked quarterly to be sure that the oil level is main-
tained at half full. A high quality gear oil with a viscosity
index of 80W or 90W and an API service rating of GL-4
or -5 is recommended for use in the gearbox. Oil
should be changed after the first 30 hours or 30 days of
operating. Then, normal change should be adequate.
In the case of seasonal usage, it is best to change the
oil at the end of the season to remove moisture and
corrosive contaminants.
Before proceeding, read and follow all safety
rules.
To change the oil, follow this procedure, Figure 12:
1. Suction out oil in gearbox through side plug using a
hand pump.
NOTE: It is best to drain the oil when the gearbox
is warm to remove the most contaminants.
2. Add 0.52 quart SAE 85W90 gear oil through side
plug. Use level hole (halfway up the backside of
gearbox) to check oil level. Add oil accordingly.
3. Install and tighten plug.

Skid Shoes
The machine is equipped with skid shoes on bottom
side of each side plate to prevent wearing frame and to
provide depth control. They should be checked occa-
sionally for wear and replaced if required.
Before proceeding, read and follow all safety
rules.
