HOW TO USE YOUR TILLER
The tiller Is a precision built machine designed for
seed bed preparation, cultivating, furrowing and
mulching. It is engineered to minimize the hardest
work in the vegetable or flower garden, to till the soil
for planting and cultivating, and to perform many other
useful labor saving tasks in the garden. With the prop¬
er amount of care and maintenance, this machine will
provide the owner with many years of service.
WHEEL POSITION
The tiller is shipped with the wheels adjusted such
that the unit sits level. During tilling as the tines enter
the ground and the front of the tiller lowers, the
wheels must be raised to level the unit, which is
essential for proper engine operation. This adjustment
is made by removing the clevis pin and hairpin clip
from wheel yoke, raising the wheels to the desired
height, and replacing the clevis pin and hairpin clip.
See figure 7.

CONTROLLING SPEED AND TILLING DEPTH:
1.
Wheel Yoke Adjustment:
Place wheel yoke so
that the wheels are forward {nearest point
between wheels and tines) for shallow tilling, cul¬
tivating and transport. The forward speed will
increase. Turn yoke around (farthest point
between wheels and tines) for deep tilling.
Fonward speed will decrease. See figure 8.
2. 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 7.
By increasing the depth of the depth stake, the for¬
ward speed of the machine is reduced, and the work¬
ing depth is increased. See figure 9. When the depth
stake 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 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 wiil permit a working depth of about four
inches. When presetting the working depth, the han¬
dles should be adjusted 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.
