Changing Speed Belts; Loading/Unloading The Tiller - Troy-Bilt 12090 Owner's Manual

Section 4: Operation
• Turn the vehicle's engine off and apply
its parking brake.
• Position the loading vehicle so that the
ramp angle is as flat as possible (the
less incline to the ramp, the better).
Loading the Tiller
I. Use loading ramps that are strong and
wide enough to safely hold the weight of
the tiller and the operator combined--
your tiller weighs between 280 and 325
Ibs.
2. Move the Tines/PTO Clutch Lever
(Figure 4-2) into DISENGAGE position.
3. Set the Depth Regulator lever (Figure
4-2) to the Travel position.
4. Move Wheel Speed Lever (Figure4-2)
into SLOWposition and reduce the
engine throttle speed.
5. Shift the Wheels/Tines/PTOLever
(Figure 4-2) into FORWARDposition and
follow the tiller up the ramps (Figure 4-7).
Checkthe wheels as you move the tiller
forward. Ensurethat they move up the
center of each ramp.
6. Prevent tiller from rolling in vehicle.
LeaveWheel Speed Lever in FASTor
SLOW position, chock wheels with blocks
and tie down the tiller.
Figure 4.7: To go up ramps, use
FORWARD drive.
Unloading the Tiller
IMPORTANT: Neverunload the tiller in
FORWARDdrive. The tiller could tip
forward and expose you to the tines
(which should be disengaged as
instructed).
I. Use loading ramps that are strong and
wide enough to safely hold the weight of
the tiller and the operator combined--
your tiller weighs between 280 and 325
Ibs.
2. Move the Tines/PTOClutch Lever
(Figure 4-2) to DISENGAGE position.
3. Set the Depth Regulator Lever (Figure
4-2) to the Travel position.
4. Move Wheel Speed Lever (Figure 4-2)
to SLOWposition and reduce the engine
throttle speed.
IMPORTANT: Look behind you before
you back down the ramp to ensure that all
is clear. While descending, keepchecking
for obstacles behind you.
5. Move and hold the Wheels/Tines/PTO
Lever into REVERSE drive and back down
the ramps (Figure 4-8). Checkthe wheels
as you move the tiller backward. Ensure
that they move down the center of each
ramp.
Figure 4-8: To go down ramps, use
REVERSE drive.
Changing Speed
Belts
Your tiller has two belt-driven speed
ranges - HIGH RANGEand LOW RANGE
- you pick one or the other by deciding
which set of pulley grooves to move the
forward belt into. By moving the belt
from one speed range into the other, in
combination with the FASTand SLOW
wheel speeds,you obtain a choice of four
different forward wheel speeds and two
different tine speeds.
To help avoid serious personal injury,
stop the engine, remove the ignition
key, disconnect spark plug wire and
move the wire away from the spark
plug, and let engine and muffler cool
downbefore changingbelt speeds.
Changing the belt from LOW range into
HIGH range (or back again) is a matter of
moving the belt from one set of pulley
grooves to a second set of pulley grooves.
This change is done quickly and without
tools (Figures 4-9 through 4-13).
Pulley
Figure 4.9: Be/t range positions.
When the tiller is moving in REVERSE, t he
wheels are powered by a rubber reverse
disc, not by the belt. Therefore, you have
only two reverse speeds SLOW and FAST,
as set with the Wheel Speed Lever.
Table 4-I shows the range of wheel and
tine speeds availablewhen using the two
belt speed ranges and the FASTand
SLOWselections on the Wheel Speed
Lever.

Changing Belt From LOW Range
to HIGH Range
1. To avoid personal injury, shut off
engine, let all moving parts come to a
complete stop, then disconnect spark
plug wire from spark plug and move it
away from spark plug before making any
adjustments. Wait for the engine and
muffler to cool down.
