Belt Maintenance
Checking the Alternator
Belt
Service Interval: After the first 10 hours
Every 100 hours
Check the condition and tension of the belt
73) after every 100 operating hours.
1. Ensure that the proper tension allows 10 mm
(3/8 inch) deflection when a force of 4.4 kg (10
lb) is applied on the belt midway between the
pulleys.
2. If the deflection is not 10 mm (3/8 inch),
loosen the alternator mounting bolts
73). Increase or decrease the tension of the
alternator belt and tighten the bolts. Check the
deflection of the belt again to ensure that the
tension is correct.

Adjusting the Traction
Drive for Neutral
Note:
If the machine has recently had the hydraulic
fluid changed or the traction motors or hoses replaced,
work out any air trapped in the system prior to
performing this procedure. To do this, operate the
machine in forward and reverse for a few minutes and
then replenish the oil as required.
Note:
When positioned on a level surface, the
machine must not creep when you release the traction
pedal.
1. Park the machine on a level surface, engage the
parking brake, lower the cutting unit to the floor,
and shut off the engine.
2. Jack up the rear of the machine until the rear
tires are off the shop floor. Support the machine
with jack stands to prevent it from falling.
Note:
On 4-wheel-drive models, the front tires
must also be off the shop floor and supported
by jack stands.
WARNING
The engine must be running so that you
can perform this adjustment. This could
cause personal injury.
Keep your hands, feet, face, and other
body parts away from any hot parts of
the engine and any rotating parts.
3. Start the engine, set the throttle to the S
position, and observe which direction the rear
tires rotate.
Important:
Make sure that the traction pedal
is in the N
EUTRAL
•
If the left rear tire is rotating, loosen the jam
nuts on the left side transmission control rod
(Figure

Note:
The forward end of the control rod
has a left-hand thread. The rear end of the
rod, which is connected to the transmission,
has a right-hand thread.
