second adjustment hole from the top (1" of
tilling depth). See Figure 4-2.

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.
3. For further depth, raise the depth stake and
side shields and also make one or two more
passes over the area.

raised to its highest position (use the bottom
adjustment hole) to give the deepest tilling depth.
