B. Replacing the Drive Belt
A WARNINC
To help avoid personal injury,
stop the engine, remove the
electric start key, disconnect
the spark plug wire and move
the wire away from the spark
plug, and let the engine and
muffler cool before removing
or replacing the drive belt.
To Remove the Belt:
1. Move Wheel s/Tines/PTO Drive
Lever to NEUTRAL position.
2. While kneeling on the right side
of the tiller, create slack in the belt
by reaching over to the left side of
the pulleys and pushing in on the
center of the belt with your finger.
3. Use your right hand to move the
belt down and away from the lower
pulley, in the direction of the en­
gine (Photo 5-17).
Photo 5-17: First move belt off the
lower pulley.
4. As shown in Photo 5-18, push
the belt upward to create slack in
the belt.
5. Lift the top half of the belt up
and over the upper pulley and the
rubber reverse disc, moving it in
front of the reverse disc (refer to
Photo 5-19).
6. Push the Wheel s/Tines/PTO
Drive Lever down into the FOR­
WARD position. This increases
the distance between the upper and
lower pulleys. Next, lift and pull
the entire belt out between the pul­
leys (Photo 5-20).
Photo 5-19: Move top half of belt
over pulley and reverse disc.
Photo 5-18: Push belt upward to
create slack.
Photo 5-20: Shift into FORWARD

To Replace the Drive Belt:
1. Place Wheels/Tines/PTO Drive
Lever in FORWARD position.
2. Squeeze the belt in the middle
and insert one end in between the
pulleys (see Photo 5-20).
3. Push belt forward then down
until it is looped over the lower
pulley (refer to Photo 5-18). Do
not yet seat it in either of the lower
pulley’s grooves.
{Hint: a blunt
object, like a ruler, can help you
push the belt downward if needed.)
4. Move the top half of the belt up
and over the rubber reverse disc,
but do not seat it in either of the
grooves in the top pulley.
5. Place the Wheels/Tines/PTO
Drive Lever in NEUTRAL.
6. Move the top half of the belt
into the HIGH Range groove
(groove closest to the engine) on
the top pulley. See Photo 5-21.

belt into the HIGH Range groove
Photo 5-21: Seat belt in upper pul­
ley, then in lower pulley (“High
Range” position shown).
of the lower pulley (groove closest
to engine). Photo 5-21. If extra
slack is needed, hold up Wheels/
Tines/PTO Drive Lever while mov­
ing the belt. Verify the belt is
seated properly on the pulleys.
