CHECKINGAND ADJUSTING
FORWARDDRIVE BELT TENSION
It is important to maintain correct tension
on the forward drive belt. A loosebelt will
causethe tinesandwheelsto slow down--
or stop completely -- eventhough the en-
gine is running at full speed.A too tight
belt can result in unintentional tine move-
ment when the clutch bail isin the Neutral
(released) position.
• Checkbelt tension after the first two
hours of break-in operation andafter every
10 operatinghours.
• At the end of each tilling season, check
the belt for cracks, cuts or frayed edges
and replace it as soonas possible.
tension is correct if this second measure-
ment is between1/6"-to- 3/16"longer than
the first measurement.
4. If the spring is too short (lessthan
1/16"), the tension is too loose. If the
spring is too long (more than 3/16"), the
tension is too tight.
5. Toadjust the length of the spring:
a. Releasethe Forward Clutch Bail.
b. Unthreadthe hex nut (C,Figure 5-4)
halfway up the adjustment screw (D).
c. Unhookthe top ofthe spring from the
Forward Clutch Bail.
d. Usepliers to preventthe adjuster (B)
from turning andturn the slotted screw lo-
cated inside the spring clockwise (viewed
from operator'sposition) to increaseten-
sion onthe spring. Turnthe screw counter-
clockwise to decreasetension. Once
adjusted, reattachthe spring to the For-
ward Clutch Bail.
e. RepeatSteps2and3to re-measurethe

ReplacementBelt Information
If the drive belt needsto be replaced,see
your local authorizeddealeror refer to the
Parts List for ordering information. Use
only a factory-authorized belt as an "over-
the-counter" belt may not perform satis-
factorily. The procedure requires average
mechanicalability andcommonly available
tools.
ToCheckForwardBeltTension:
1. Stop engine, wait for all parts to stop
moving and disconnect spark plug wire.
2. With the ForwardClutchBailinan open
(released) position, measureand note the
overall length of the cable spring (A, Figure
5-4) by measuringfrom the outermost coil
to the outermost coil.
