CHAPTER 8
LUBRICATION
GENERAL INFORMATION
WARNING
NEVER attempt to lubricate the machine when
any part of the unit is in motion. ALWAYS BE
SURE to exercise the MANDATORY SAFETY
SHUTDOWN PROCEDURE (page 8), BEFORE
lubricating the machine.
Proper lubrication of the disc mower will prevent
excessive part wear and early failure.
IMPORTANT: Whenever service is performed
on hydraulic components (valves, cylinders,
hoses, etc.) or transmission, care must be taken
to prevent discharging fluid onto the ground.
Catch and dispose of fluid according to
environmental law.
BEVEL GEARBOX (Fig. 14)
A plug (Ref. 1) is provided for checking the oil level in
the gearbox when the cutterbar is in the horizonal
position. This plug is also used as a gearbox drain when
the cutterbar is in the vertical transport position. The oil
should be changed every 200 hours of operation or
annually (more often if operated under heavy loads). An
oil fill plug (Ref. 2) is provided on the top of the gearbox
for adding or changing oil. The gearbox holds 0.5 U.S.
qts. (0.45 L). Use SAE 80W90 GL5 EP oil.
A pressure relief valve (Ref. 3) is located on the side of
the gearbox and must be removed and cleaned each time
the gearbox oil is changed. BE SURE that the ball detent
moves freely to relieve pressure.
The gearbox should be checked occasionally for oil
drips and dust accumulation around the seals. Oil drips
or dust accumulation indicate that seals are leaking. Oil
which is tan in color and foams excessively indicates
that it has water present.
IMPORTANT: The oil in the gearbox MUST be
changed after the first 10 hours of operation. BE
SURE to also clean and check the pressure relief
valve at this time.

CUTTERBAR (Fig. 15)
To check the oil in the cutterbar, park the tractor on level
ground and place the cutterbar in the vertical transport
position. A plug (Ref. 1) is provided for checking the oil
level in the cutterbar. The oil level is correct when the
oil just begins to flow out of the hole. The oil should be
changed every 200 hours or annually (more often if
operated under heavy loads). The following procedure
MUST be followed:
1. Operate the disc mower for 10 minutes so that the
cutterbar reaches operating temperature.
2. Raise the disc mower to the vertical transport posi-
tion and be sure the transport lock is engaged.
3. Exercise the MANDATORY SAFETY SHUT-
DOWN PROCEDURE (page 8).
4. Remove the magnetic drain plug (Ref. 2) and the
oil level/fill plug, allowing the oil to drain com-
pletely. Wait for the dripping to stop.
5. BE SURE to clean the magnetic drain plug thor-
oughly before installation.
6. Refill the cutterbar with SAE 80W90 GL5 oil.
The cutterbar holds 2.1 U.S. qts. (2 L). and rein-
stall the oil level/fill plug.
