harder at this point).

afirm grip on the handle. Let the rope rewind slowly. Do not let the recoil starter snap back against the engine. Repeat until the engine starts.

The working depth of the machine may be predetermined by setting the depth stake so that the wheels are about four inches from the ground when the tines and depth stake are resting on

the ground. This setting will permit aworking depth of about four inches. When presetting the working depth, the handles should be adjusted so the hand grips are a little above the waist. The tiller will be lower when the tines and depth stake penetrate the ground.

For tilling, the depth stake must be lowered and the wheel must be raised. See Fig. 5-1.

Figure 5-1

When tilling, leave approximately eight inches of untilled soil between the first and second tilling paths, then make the third

path between the first and second. See Fig. 5-2.

Stopping Engine

1. Move the throttle control lever (if equipped) to STOPor OFFposition. Referto the engine manual for instructions on stopping the engine.

2. Disconnect the spark plug wire from the spark plug and ground against the engine.

UsingYourTUler

Your tiller is designed for seed bed preparation, cultivating, furrowing, and mulching.

Controlling Tilling and DepthSpeed

Byincreasing the depth of the depth stake, the forward speed of the machine isreduced and the working depth is increased. When the depth stake is raised, the working depth of the

machine isreduced and the forward speed is increased.

whichareturnedupshouldberemovedfromthegardenarea.

HandlePressure

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.

Cultivating

For cultivating, a two to three inch depth is desirable. With the outer tines installed, the working width of the machine is 22 or

24 inches. For cultivation, the tine width can 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, Fig. 5-3.

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 allows proper aeration of the plant root system and retards the growth of weeds.

TransportingandStoringthe TUler

To transport the tiller, lower the wheel and move the depth stake to the highest position. See Fig. 5-4.

Figure 5-3

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.

Figure 5-4

To store the tiller, lower the wheel and orient the depth stake so both are touching the ground. See Fig. 5-5.
