Adjustments
Wheel Gear Cable
When the Wheel Gear Lever is in DISENGAGE, the wheels will roll
freely (freewheel). The wheels should not roll freely when the
lever is in ENGAGE. If the wheels roll freely when the Wheel Gear
Lever is in ENGAGE, the wheel gear cable needs to be adjusted as
described below.
With the engine shut off and the spark plug wire
disconnected, put the Wheel Gear Lever in ENGAGE.
Loosen the top adjustment nut on the wheel gear
cable bracket that is located on the left side rear of the
transmission. See Fig. 6-3.
Push the wheel gear cable down and roll the tiller slightly
forward or backward until the eccentric lever engages
(locks) the wheels. Hold the cable in that position and
tighten the top and bottom adjustment nuts.
Move the Wheel Gear Lever to ENGAGE and DISENGAGE
several times to check the adjustment. The wheels should
not roll when the lever is in ENGAGE, but they should roll
when the lever is in DISENGAGE. Readjust the cable as
required.
Forward Clutch Belt
Maintaining the correct belt tension 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 — even though the engine is running at
full speed. A loose belt will also result in premature belt wear.
While checking the belt tension, also check for cracks, cuts or
frayed edges. A belt in poor condition should be replaced as
soon as possible.

Tension on a new forward clutch belt should be checked after
the first two (2) hours of operation and after every ten (10) hours
of operation after that. See Fig. 6-4.
Before checking, shut off the engine, allow the engine
and muffler to cool down, disconnect the spark plug wire
remove the ignition key on electric start models.
The coiled part of the forward clutch spring measures 2”
in length when the Forward Clutch Control levers are not
pulled up. Pull either the Forward Clutch Control Lever
up against the handlebar and measure the length of the
coil on the forward clutch spring. Tension is correct if the
length of the extended coil is 2-1⁄2”. The forward clutch
control cable needs adjustment if the extended length of
the coil is not 2-1⁄2”. See Fig. 6-5.
