Section 4: Operation
CHANGING BELT RANGE SPEEDS
The tiiler has two belt range speeds for
the wheels and tines: Low and High. The
two ranges are obtained by moving the
forward drive belt between two sets of
grooves on the forward drive pulley and
the transmission drive pulley. The decal
on top of the belt cover shows the two
belt speed positions.
NOTE: The tiller is shipped from the
factory with the belt in the Low range
position. Keep the belt in this range while
familiarizing yourself with the tiller.
Use the Low speed range when more
power is needed, such as tilling sod and
unworked soil or for tilling under cover
crops or extremely heavy weeds.
Use the High speed range for shallow cul¬
tivating, final seedbed preparation and for
power composting heavy leaves, straw,
mulch, or composted material. However,
if the ground is very hard, you may need
to use the Low speed range for better
results.
A WARNING
Before changing belt speeds,
stop engine, wait for all parts
to stop moving, let engine
cool and disconnect spark
plug wire.
Remove ignition
key on electric start models.
Failure
to
follow
these
instructions could result in
personal injury.
To Change from Low to High Speed:
1. Stop the engine, allow it to cool, and
disconnect 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
forward drive belt out of the transmission
low speed groove (B, Figure 4-11) 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 puiley low speed groove (A, Figure
4-11) and into the high speed groove (C).
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 4-11 and 4-12) on
the right-side of the unit and is within the
forward idler (F, Figure 4-12) on the left¬
side. Be sure that the belt is situated in
the center grooves (C and D, Figure 4-11)
of the engine (upper) and transmission
(lower) pulleys.
7. Reinstall the plastic belt cover and
secure it with the two nuts.
8. Put Wheel Gear Lever in ENGAGE and
reconnect spark plug wire before attempt¬
ing to start the engine.
