considerable distance, transport it on a truck or trailer.
Whenever traction unit is pushed or towed, by-pass valve
must be open.
1. Remove hair pin, pivot seat platform forward and locate

3. Start engine momentarily after repairs are completed
and make sure the pins are in the full disengaged (fully
up) position.
Important Running the machine with by-pass valve
open will cause the transmission to overheat.

Lubrication

Greasing Bearings And
Bushings
The traction unit has grease fittings that must be lubricated
regularly with No. 2 General Purpose Lithium Base Grease.
If machine is operated under normal conditions, lubricate
all bearings and bushings after every 50 hours of operation.
Bearings and bushings must be lubricated daily when
operating conditions are extremely dusty and dirty. Dusty
and dirty operating conditions could cause dirt to get into
the bearings and bushings, resulting in accelerated wear.
Lubricate grease fitting immediately after every washing,
regardless of interval specified.
Apply a liberal coating of grease to the check valve pins
once each year (Fig. 26). Also grease the bearings in the
rear axle every 500 hours, or yearly, whichever comes first
(not shown). The traction unit has bearings and bushings
that must be lubricated, and these lubrication points are:
PTO universal shaft (Fig. 27); lift arm pivot bushings
(Fig. 28), brake pivot bushings (Fig. 29); Drive shaft (3)
(Fig. 30); tie rod ends (2), cylinder rod ends (2), steering
pivots (2) and axle pivot pin (Fig. 31); PTO tension pivot
(Fig. 32) and rear PTO bearing (Fig. 32). Also apply grease
to both brake cables at the drive wheel and brake pedal
ends (Fig. 29).
1. Wipe grease fitting clean so foreign matter cannot be
forced into the bearing or bushing.
2. Pump grease into the bearing or bushing.
3. Wipe up excess grease.
