Caution
If you leave the key in the ignition switch, someone could accidently start the engine and
seriously injure you or other bystanders.
Remove the key from the ignition and disconnect the wire from the spark plug before you do any
maintenance. Set the wire aside so that it does not accidentally contact the spark plug.
Lubrication
The traction unit has grease fittings that must be lubricated
regularly with No. 2 General Purpose Lithium-Base
Grease. If the machine is operated under normal conditions,
lubricate all bearings and bushings after every 50 hours of
operation.
The following traction unit bearings and bushings must be
lubricated:
•
Rear wheel bearings (1) (Fig. 26)
•
Steering fork shaft (1) (Fig. 27)
•
Lift arm pivot (3) and pivot hinge (3) (Fig. 28)
•
Pull frame shaft and roller (12) (Fig. 29)
•
Power steering cylinder (Fig. 30)
•
Mow lift pivot (Fig. 31)
•
Lift cylinders (3) (Fig. 32)
•
Mow lockout lever (Fig. 33)
1.
Wipe the grease fitting clean so foreign matter cannot
be forced into the bearing or bushing.
2.
Pump grease into the bearing or bushing until the grease
is visible. Wipe up excess grease.
3.
Apply grease to the reel motor spline shaft and onto the
lift arm when the cutting unit is removed for service.
4.
Apply a few drops of SAE 30 engine oil or spray
lubricant (WD 40) to all pivot points daily after
cleaning.
