WARNING: Before
changing belt speeds, stop
engine, wait for all parts to stop
moving, let engine cool and
disconnect spark plug wire.
Failure to follow these
instructions could result in
personal injury.
Changing Belt Range Speeds
The tiller has two forward belt range speeds
for the wheels and tines: Low and Fligh. The
two ranges are obtained by moving the for­
ward drive belt between two sets of
grooves on the forward drive pulley and the
transmission drive pulley.
NOTE: The Fligh speed belt range is recom­
mended for all tilling purposes. The Low
speed belt range will operate the tines and
wheels at a slower forward speed, which
may be suitable in some conditions (such
as tilling in very hard ground).
To Change from Low to High Speed:
1. Stop the engine, allow it to cool, and dis­
connect the spark plug wire.
2. Move the Wheel Gear Lever into the DIS­
ENGAGE position.
3. Remove the two nuts from the plastic
belt cover on top of the transmission and
remove the belt cover.
4. From beneath the tiller, move the for­
ward drive belt out of the transmission low
speed groove (B, Figure 4-10) and into the
high speed groove (D).
5. Pull upward on the belt to remove any
slack and slip the belt out of the engine
drive pulley low speed groove (A, Figure 4­
10) and into the high speed groove (C).
NOTE: If the belt is difficuitto move, pull on
the engine start rope while pushing the belt
with your finger (engine drive pulley will
turn as start rope is pulled).
6. Check that the belt is within the forward
belt guide (E, Figures 4-10 and 4-11) on the
right-side of the unit and Is within the for­
ward idler (F, Figure 4-11) on the left-side.
Be sure that the belt is situated in the center
grooves (C and D, Figure 4-10) of the en­
gine (upper) and transmission (lower) pul­
leys.
7. Reinstall the plastic belt cover and se­
cure it with the two nuts.
8 . Put Wheel Gear Lever in ENGAGE and re­
connect spark plug wire before attempting
to start the engine.
To Change from High to Low Speed:
1. Stop the engine, allow it to cool, and dis­
connect the spark plug wire.
2. Put Wheel Gear Lever in DISENGAGE.
3. Remove the two nuts from the plastic
belt cover on top of the transmission and
remove the belt cover.
4. From beneath the tiller, move the for­
ward drive belt out of the transmission pul­
ley high speed groove (D. Figure 4-10) and
into the low speed groove (B).
5. Pull upward on the belt to remove any
slack and slip the belt out of the engine
drive pulley high speed groove (C, Figure 4­
10) and into the low speed groove (A).
NOTE: If the belt is difficult to move, pull on
the engine start rope while pushing the belt
with your finger (engine drive pulley will
turn as start rope is pulled).
6. Check that the belt is within the forward
belt guide (E, Figures 4-10 and 4-11) on the
right-side of the unit and is within the for­
ward idler (F, Figure 4-11) on the left-side.
Be sure that the belt is situated in the rear
grooves (A and B. Figure 4-10) of the en­
gine (upper) and transmission (lower) pul­
