Checking and Adjusting Forward Drive Belt
Tension
It is important to maintain correct tension on the forward drive
belt. A loose belt will cause the tines and wheels to slow down
— or stop completely — even though the engine is running at full
speed. A too-tight belt can result in unintentional tine movement
when the lever is in the Neutral (released) position.
– Check belt tension after the first two hours of break-in
operation and after every 10 operating hours.
– At the end of each tilling season, check the belt for cracks,
cuts or frayed edges, and replace it as soon as possible.
To Check Belt Tension:
1. Stop engine, wait for all parts to stop moving and disconnect
spark plug wire.
2. With the forward and reverse lever in an open (released)
position, measure and note the overall length of the cable
spring by measuring from the outermost coil to the outermost
coil.

REVERSE LEVER
3. Squeeze the forward lever against the handlebar and re-
measure the length of the coils. The belt tension is correct if
this second measurement is between 1/6 in. to 3/16 in. (2-5
mm) shorter than the first measurement.
4. If the spring is too short (less than 1/16 in. [2 mm]), the
tension is too tight. If the spring is too long (more than 3/16
in. [5 mm]), the tension is too loose.
5. To adjust the length of the spring.
1. Release the forward lever.
2. Un-thread the hex nut halfway up the adjustment screw.
3. Unhook the top of the spring from the lever.
4. Use pliers to prevent the adjuster from turning and turn
the slotted screw located inside the spring clockwise
(viewed from operator's position) to increase tension on
the spring. Turn the screw counter-clockwise to decrease
tension. Once adjusted, reattach the spring to the lever.
5. Repeat Steps 2 and 3 to re-measure the length of the
spring. When the second measurement is between
1/16 in. to 3/16 in. (2 to 5 mm) shorter than the first
measurement, re-tighten the hex nut against the top of
the adjuster.
