WHEEL POSITION
The tiller is shipped with the wheels adjusted
such that the unit sits level. During digging as the
tines enter the ground and the front of the tiller
lowers, the wheels must be raised to level the
unit. This is essential for proper engine operation.
This adjustment is made by removing the clevis
pin and hairpin cotter from wheel yoke, raising the
wheels to the desired height, and replacing the
clevis pin and hairpin cotter. See figure 15.

CONTROLLING SPEED AND TILLING DEPTH:
1. Wheel Yoke Adjustment: Place wheel yoke so
that the wheels are forward (nearest point be­
tween wheels and tines) for shallow tilling,
cultivating and transport. This will increase
the forward speed. See figure 16. Turn yoke
around (farthest point between wheels and
tines) for deep tilling. Forward speed will
decrease. See figure 16.

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 17. Remove the clevis pin and
spring pin to raise or lower depth bar.

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 forward 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 working depth of about
four inches. Use maximum engine speed for
deep tilling. When presetting the working
depth, the handles should be a little above
waist height because the 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. 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.
3. Handle Pressure: Further control of tilling
depth and travel speed can be obtained by
variation of pressure on the handles. A
downward pressure on the handles will
reduce the working depth and increase the
