Tilling depth is controlled by the depth stake which can
be adjusted to five different settings. See Figure 7.
Adjust the side shields as shown in Figure 8, as you
adjust the depth stake. Be certain spark plug wire is
disconnected and grounded against the engine.

When using the tiller for the first time, use the
second adjustment hole from the top (1" of tilling
depth). See Figure 7.

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.
•
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.
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 7. Move the depth
stake to the desired setting.
