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.

The throttle control lever adjusts the engine speed and 
stops the engine. With the throttle control lever pushed 
completely forward, the carburetor is in START 
position. Pulling the throttle control back slightly adjusts 
the engine speed to FAST. Pulling the throttle back 
further reduces the engine speed to SLOW. Pull the 
throttle completely back to stop the engine.
Use maximum engine speed for deep tilling. Move the 
throttle control to SLOW when transporting the tiller.

To transport the tiller to or from the garden, pivot the 
depth stake forward, out of the way.  See Figure 10. 
With the throttle control in SLOW position, the unit will 
walk freely on top of the lawn. If the operator does not 
allow the tiller to move freely, the unit will start to till the 
surface.

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 tines 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 12.

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 handwork 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 also retards the growth of weeds.
