Off-Season Storage - Troy-Bilt Bronco Manual Del Operador

Adjustments
Forward Drive Belt
It is important to maintain the 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 belt that is too tight can result in
unintentional tine movement when the clutch bail is in the
Neutral (released) position.
• Check the 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.
Check the Forward Belt Tension:
1. Stop the engine, wait for all parts to stop moving and
disconnect the spark plug wire.
2. With the Forward Clutch Bail 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.
See Fig. 6-3.

3. Squeeze the Forward Clutch Bail against the handlebar
and re-measure the length of the coils. The belt tension is
correct if this second measurement is between 1⁄6" -to- 3⁄16"
longer than the first measurement.
4. If the spring is too short (less than 1⁄16"), the tension is too
loose. If the spring is too long (more than 3⁄16"), the tension
is too tight.
5. To adjust the length of the spring:
a. Release the Forward Clutch Bail.
b. Unthread the hex nut halfway up the adjustment
screw.
c. Unhook the top of the spring from the Forward
Clutch Bail.

d. 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
counterclockwise to decrease tension. Once
adjusted, reattach the spring to the Forward Clutch
Bail.
e. Repeat Steps 2 and 3 to re-measure the length of the
spring. When the second measurement is between
1⁄16" -to- 3⁄16" longer than the first measurement,
retighten the hex nut against the top of the adjuster.

Off-Season Storage

When the tiller won't be used for an extended period, prepare it
for storage as follows:
1. Clean the tiller and engine.
2. Do routine tiller lubrication and check for loose parts and
hardware.
3. Protect the engine and perform the recommended engine
maintenance by following the storage instructions found
in the Engine Operator's Manual. Be sure to protect the
fuel lines, carburetor and fuel tank from gum deposits
by removing fuel or by treating fuel with a fuel stabilizer
(follow the engine manufacturer's recommendations).
4. Store the tiller in a clean, dry area.
5. Never store the tiller with fuel in the fuel tank in an
enclosed area where gas fumes could reach an open flame
or spark, or where ignition sources are present (space
heaters, hot water heaters, furnaces, etc.).
