WHEEL POSITION
The tiller is shipped with the wheels adjusted sue h that
the unit sits level. During digging as the tines enl er the
ground and the front of the tiller lowers, the wheel:: must
be raised to level the unit, which is essential for f iroper
engine operation. This adjustment is made by remov­
ing the clevis pin and hairpin clip from wheel yoke, rais­
ing the wheels to the desired height, and replacii ig the
clevis pin and hairpin clip. See figure 18.

CONTROLLING SPEED AND TILLING DEPTH:
1. Wheel Yoke Adjustment: Place wheel yo :e so
that the wheels are forward (nearest point bet ween
wheels and tines) for shallow tilling, cultivatin j and
transport. The forward speed will increase. Turn
yoke around (farthest point between wheel:: and
tines) for deep tilling. Forward speed will deer jase.
See figure 19.

Depth Stake Adjustment: The depth stake acts
as a brake for the tiller and controls the depth and
speed at which the machine will operate. Remove
the clevis pin and hairpin clip to raise or lower
depth stake. See figure 18.
By increasing the depth of the depth stake, the for­
ward speed of the machine is reduced, and the
working depth is increased. See figure 20. When
the depth stake is raised, the working depth of the
machine is reduced and the forward speed is in­
creased. The working depth of the machine may
be predetermined by setting the depth stake and
wheels so that the wheels are about four inches
from the ground when the tines and depth stake
are resting on the ground. This setting will permit
a working depth of about four inches. When preset­
ting the working depth, the handles should be ad­
justed so the hand grips are a little above waist
height because the tiller will be lower when the
tines and depth stake penetrate the ground.

When tilling, leave approximately 8 inches of un­
filled soil between the first and second tilling paths,
then make the third path between the first and sec­
ond as shown in figure 21. In some soils, the
desired depth is obtained the first time over the
garden. In other soils, the desired depth is obtained
by going over the garden two or three times. In the
latter case, the depth stake should be lowered
before each succeeding pass over the garden.
Passes should be made across the length and
width of the garden alternately. Rocks which are
turned up should be removed from the garden
area.
