Lubrication
Traction Unit
CAUTION
Before servicing or making adjustments to the
machine, stop engine, lower cutting units, set
parking brake, and remove key from the ignition
switch.
The traction unit has grease fittings that must be lubri-
cated regularly with No. 2 General Purpose Lithium
Base Grease. If machine is operated under normal
conditions, lubricate bearings and bushings after every
50 hours of operation. Bearings and bushings must be
lubricated daily when operating conditions are extreme-
ly dusty and dirty. Dusty and dirty operating conditions
could cause dirt to get into the bearings and bushings,
resulting in accelerated wear. Lubricate bearings and
bushings immediately after every washing, regardless
of the interval listed.
The traction unit bearings and bushings that must be lu-
bricated are: Rear cutting unit pivot (Fig. NO TAG),
Front cutting unit pivot (Fig. 2), Sidewinder cylinder ends
(qty. 2) (Fig. 3), Steering pivot (Fig. 4), Rear lift arm pivot
and lift cylinder (qty. 2) (Fig. 5), Left front lift arm pivot
and lift cylinder (qty. 2) (Fig. 6), Right front lift arm pivot
and lift cylinder (qty. 2) (Fig. 7), Neutral adjust mecha-
nism (Fig. 8), Mow/Transport slide (Fig. 9), Belt tension
pivot (Fig. 10), and Steering cylinder (Fig. 11).
Note: If desired, an additional grease fitting may be
installed in other end of steering cylinder. Tire must be
removed, plug removed, fitting installed, greased, fitting
removed and plug reinstalled (Fig. 12).
IMPORTANT: Do not lubricate Sidewinder cross
tube: bearing blocks are self lubricated.
IMPORTANT: Lubricate bearings and bushings im-
mediately after washing. This helps to purge water
out of bearings and increases bearing life.
1. Wipe each grease fitting with a clean rag.
IMPORTANT: Do not apply too much pressure or
grease seals will be permanently damaged.
2. Apply grease until pressure is felt against handle.
3. Wipe excess grease away.
