FORWARD DRIVE BELT TENSION
FORWARD DRIVE BELT TENSION
Maintaining correct tension on the
forward drive belt is important to good
tilling performance and long belt life.
forward drive belt is important to good
tilling performance and long belt life.
A loose belt will slip on the engine and
transmission pulleys and cause the tines
and wheels to slow down – or stop com-
pletely – even though the engine is
running at full speed. A belt that is too
tight can result in unintentional tine
movement when the clutch bail is in the
Neutral (released) position.

Also check the belt for cracks, cuts or
frayed edges and replace it as soon as
possible.

• Check belt tension after the first two
hours of break-in operation (new belt).
• Check belt tension after every 10
operating hours.
To Check Forward Belt Tension:
1. Stop the engine, wait for all parts to
stop moving and disconnect the spark
plug wire.
stop moving and disconnect the spark
plug wire.
2. With the forward clutch bail in an open
(released) position, measure and carefully
note the overall length of the cable spring
(A, Figure 5-4) by measuring from the
outermost coil to the outermost coil.

3. Lift and hold the forward clutch bail
against the handlebar (see Figure 5-4) and
against the handlebar (see Figure 5-4) and
re-measure the overall length of the coils
while the spring is under tension. The belt
tension is correct if this second measure-
ment is between 1/16" -to- 3/16" longer
than the first measurement.
while the spring is under tension. The belt
tension is correct if this second measure-
ment is between 1/16" -to- 3/16" longer
than the first measurement.
4. If the spring is too short (less than
1/16" greater than the first measurement),
the tension is too loose. If the spring is
too long (more than 3/16" greater than the
first measurement), the tension is too
tight.
1/16" greater than the first measurement),
the tension is too loose. If the spring is
too long (more than 3/16" greater than the
first measurement), the tension is too
tight.
5. To adjust the length of the spring:
a. Release the Forward Clutch Bail.
b. Unthread the hex nut (C, Figure 5-4)
b. Unthread the hex nut (C, Figure 5-4)
about halfway up the adjustment

screw (D).
c. Unhook the top of the spring from
the forward clutch bail.
d. Use pliers to prevent the adjuster (B)
from turning and turn the slotted
screw located inside the screw
clockwise (viewed from operator’s
position) to increase tension on the
spring. Turn the screw counter-
clockwise to decrease tension on the
spring. Once adjusted, rehook the
top of the spring to the forward
clutch bail. (Continue to Step 5e.)

the overall length of the coils in the spring – first with the clutch bail
open, then with the clutch bail closed against the handlebar.
