• 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 also make one or two more passes
over the area.
• When tilling loose soil, the 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.
• To transport tiller, lower the depth stake (use top
adjustment hole).
To adjust the depth stake, remove the clevis pin and
hairpin clip. Move the depth stake to the desired setting
and secure with the clevis pin and hairpin clip.
See Figure 10.
To adjust the side shields, remove the wing nuts. Move
the side shield to the desired position and replace the
wing nuts. Tighten securely.
Operating the Tiller
• Select the depth stake setting.
• Start engine as instructed on the previous page.
• 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.
• 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, do not 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.
SECTION 5: MAKING ADJUSTMENTS
WARNING: Never attempt to make any
adjustments while the engine is running,
except where specified in operator’s
manual.
Handle Adjustment
The handle may be adjusted to the height desired and
on Model 420 series, the handle may also be adjusted
to be in line with the tiller or swung to the left or right.
Refer to the handle adjustment in the Know Your Tiller
section for details.
Belt Tension Adjustment
Periodic adjustment of the belt tension may be required
due to normal stretch and wear on the belt. Adjustment
