Section 4: Operation

3. Kneel on left side of tiller. To create

belt slack, reach over to right side of the

pulleys and push in at the center of the

belt with a finger. At the same time, use

your left hand to work the belt part-way

onto the lower-front transmission pulley

groove (Figure 4-10).

4. Go to the other side of the tiller to

finish seating the belt onto the pulley

groove.
5. Working from the left side of the tiller,

work the belt as much as possible onto

the top-front engine pulley groove (Figure

4-11).
6. Finish seating the belt from the right

side of the tiller.
IMPORTANT: Proper belt tension is

important for good performance. See

Section 5, Drive Belt Maintenance for

information on belt maintenance schedule

and procedures.
NOTE: If extra belt slack is needed to

move the belt, just raise the Wheels/Tines/

PTO Drive Lever up into REVERSE. This

lowers the engine pulley, and creates

more slack.

7. Check both sides of the high range

pulley grooves to verify that the belt is

properly seated.

Changing Belt From HIGH Range to

LOW 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 wire

away from spark plug before making any

adjustments. Let engine and muffler cool.
2. Move the Wheels/Tines/PTO Drive

Lever into NEUTRAL.
3. Stand on left side of tiller. Use your

right hand to hold the Wheels/Tines/PTO

Drive Lever up into REVERSE position.

Use your left hand to move the belt off

top-front engine pulley groove to top-rear

engine pulley groove (Figure 4-12).

4. Go to right side of tiller and finish

seating the belt.
5. Still holding the lever up in REVERSE

position, and working from the left side

of the tiller, move the belt from the lower-

front transmission groove to the lower-

rear transmission groove.
6. Go to the right side of the tiller and

finish seating the belt (Figure 4-13).

7. Check that the belt is fully seated in

the pulley grooves. Check this from both

sides of the tiller.

Choosing Wheel

and Tine Speeds

Your tiller has four FORWARD wheel/tine

speed combinations for handling a variety

of tilling tasks and gardening jobs. Exper-

iment with the tine depth, engine speed,

and wheel/tine speed and determine

the combination that provides the best

results. Here are some tips:
1. Advance the throttle lever so the engine

has sufficient power.
2. When tilling untilled or hard earth, do

not set the Depth Regulator too deep. The

tiller will buck and the engine will load

down.
3. You will know your settings are ideal

when the tines break-up the soil easily, the

engine does not labor, and your progress

is steady and smooth.
See Table 2, Wheel Speed and Belt Range

Selection Guide for recommendations.

front groove onto top-rear pulley
groove.

Figure 4-13: High range to low
range. Shows moving belt from
lower-front onto lower-rear groove.

Figure 4-11: Low range to high
range. Shows moving belt from top-
rear groove onto top-front groove.

groove onto lower-front groove.

The HIGH speed belt range position

combined with a FAST wheel speed

setting propels the tiller at the fastest

pace. Reduce the engine throttle speed

when starting out to help avoid personal

injury or property damage if using this

speed combination.
