SECTION 8: HOW TO USE YOUR TILLER
WARNING:
When operating the tiller
for the first time, use the depth stake
setting that gives 1 inch of tilling depth
(second hole from the top). Refer to
Figure 14.
Tilling depth is controlled by the depth stake which
can be adjusted to five different settings. See Figure
14. Adjust the side shields as shown in Figure 15,
as you adjust the depth stake. Be certain spark plug
wire is disconnected and grounded against the
engine.
1. When using the tiller for the first time, use the
second adjustment hole from the top (1" of
tilling depth). See Figure 14.

2. When breaking up sod and for shallow
cultivation, use the setting which gives 1" of
tilling depth (second hole from the top). Place
the side shields in their lowest position. For
further depth, raise the depth stake and side
shields and make one or two more passes over
the area.
3. When tilling loose soil, depth stake may be
raised to its highest position (use bottom
adjustment hole) to give the deepest tilling
depth. Raise the side shields to their highest
position.
4. To transport tiller, lower the depth stake (use
top adjustment hole).
To adjust the depth stake, remove the clevis pin and
hairpin clip. See Figure 14. Move the depth stake to
the desired setting
.
Secure with the clevis pin and
hairpin clip.
To adjust the side shields, remove the wing nuts.
See Figure 15. Move the side shield to the desired
position. Replace the wing nuts. Tighten securely.
To operate the tiller:
1. Select the depth stake setting.
2. Start engine as instructed on page 9.
3. Move gear selection handle to one of the
forward modes or reverse.
WARNING:
Do not move the gear
selection handle with the wheels or
tines engaged. Make certain the unit is
stopped completely before changing
the gear selection.
A partial engagement may be
necessary when engaging tines. Refer
to “Controls” section on page 8.
4. Squeeze the clutch handle against the handle
to engage the wheels and tines.
NOTE:
Make certain the gear selection indicator is
correctly positioned before engaging the clutch
handle. If it is between gears, the engine will stall.
To transport tiller,

engage the tines. Select
the wheel drive only.
WARNING:
Do not push down on the
handles so that the wheels are lifted off
the ground while using the tine drive,
or the tiller could move backward and
cause personal injury.
For best results, it is recommended the garden be
tilled twice (lengthwise, then widthwise) to pulverize
the soil.
