Troy-Bilt 769-03618 Manual De Usuario

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 Forward Belt Tension (refer to Fig. 6-3):

Stop engine, wait for all parts to stop moving and 

disconnect spark plug wire.
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.
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 1⁄16” -to- 3⁄16” 

longer than the first measurement.
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.
To adjust the length of the spring: 

Release the Forward Clutch Bail.
Unthread the hex nut halfway up the adjustment 

screw. 
Unhook the top of the spring from the Forward 

Clutch Bail.

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. 
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. 

Check the belt tension after the first two hours of break-in 

operation and after every 10 operating hours.
To Check Reverse Belt Tension (Refer to Fig. 6-4):

Stop the engine, wait for all parts to stop moving and 

disconnect the spark plug wire.
Remove the screw in the plastic belt cover and slide the 

belt cover — which is attached to forward clutch cable 

— out of the way.
Have an assistant pull the Reverse Clutch Control knob all 

the way out and hold it in that position. Measure the length 

of the cable wire between the end of the threaded cable 

adjuster and the end of the Z-fitting to which the cable 

wire is attached. 
The belt tension is ideal if the cable wire length measures 

between 1⁄8” to 1⁄4”. If it is less than 1⁄8” (and if there is no 

reverse action when the tiller is running), then make the 

following adjustments 
NOTE: If the length is more than 1⁄4”, no adjustment is 

needed — as long as the reverse action functions properly.
Release the Reverse Clutch Control knob and then 

unthread the inner jam nut one to two turns. Pull the 

threaded cable adjuster to the left until the inner jam nut 

touches the bracket.
