WHEEL POSITION
The tiller is shipped with the wheels adjusted stch that
the unit sits level. During digging as the tines er ter the
ground and the front of the tiller lowers, the whee Is must
be raised to level the unit. This is essential for proper
engine operation. This adjustment is made by 'emov-
ing the clevis pin and hairpin cotter from wheel yoke,
raising the wheels to the desired height, and re| )lacing
the clevis pin and hairpin cotter. See figure 1
9.
2. Depth Bar Adjustment: The depth bar acts as a
brake for the tiller and controls the depth and speed
at which the machine will operate. See figure 21.
Remove the clevis pin and hairpin cotter to raise or
lower depth bar.

CONTROLLING SPEED AND TILLING DEPTH:
1. Wheel Yoke Adjustment: Place wheel yske so
that the wheels are forward (nearest point between
wheels and tines) for shallow tilling, cultivatir g and
transport. This will also increase the forward speed.
See figure 20. Turn yoke around (farthest point between
wheels and tines) for deep tilling. Forward speed will
decrease. See figure 20.

By increasing the depth of the depth bar, the forward
speed of the machine is reduced, and the working
depth is increased. When the depth bar is raised, the
working depth of the machine is reduced and the for­
ward speed is increased. The working depth of the
machine may be predetermined by setting the depth
bar and wheels so that the wheels are about four inches
from the ground when the tines and depth bar are
resting on the ground. This setting will permit a work­
ing depth of about four inches. When presetting the
working depth, the handles should be a little above
waist height because the complete tiller will be lower
when the tines and depth bar penetrate the ground. The
best method will be determined by the soil condition.
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 bar should be lowered
before each succeeding pass over the garden, and
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.
