which are turned up should be removed from the
garden area. See Figure 10.

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 forward speed.
An upward pressure on the handles will increase
the working depth and reduce the forward speed.
The type of soil and working conditions will determine
the actual setting of the depth stake and the handle
pressure required.
Transporting The Tiller
To transport the tiller to or from the garden, pivot the
depth stake forward and out of the way. With the throttle
control in SLOW position, the unit will walk freely on the
lawn. If the operator does not allow the tiller to move
freely, the unit will start to till the surface. Refer to
Figure 9
Cultivating
For cultivating, a two to three inch depth is desirable.
Setting the wheels and depth stake so that the wheels
are about two inches above the ground while the tiller is
resting on the tines and depth stake will allow the
machine to work at cultivating depth. The throttle
should be set to control forward movement to a slow
walking speed. With the outer tine installed, the working
width of the machine is 22 or 24 inches. For cultivation,
this may be reduced to 13 inches by removing the outer
tines. Refer to the Adjustment Section. When laying out
plant rows, be sure to allow enough width to permit
cultivation between the rows. In growing corn or similar
crops, check-row planting will permit cross cultivation
and practically eliminate hand hoeing. See Figure 11.

The tiller has many uses other than tilling and
cultivating a garden. One of these is the preparation of
lawn area for seeding. The tiller will prepare a deep
seed bed which will be free of hard untilled spots,
allowing a better stand of grass to grow. The tiller is
very useful for loosening hard soil for excavation with a
shovel. No tedious hand work will be necessary. Your
tiller may be used for mixing compost in the pile, or for
mixing it with the soil in your garden. This should be
done after the soil has been broken to the full working
depth. The compost should be worked in to a depth of
six to seven inches. This may be done by working the
length of the garden, and then by making separate
passes across its width. The addition of decayed
organic matter will substantially increase the fertility of
your garden. For proper decaying action, fertilizer
should be applied and worked in with the mulch
materials. Breaking up leaves and straw and mixing it
with several inches of soil causes the soil to hold
moisture longer and allows proper aeration of the plant
root system. This retards the growth of weeds.
