Using Your Tiller

Your 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 planning

and cultivating, and to perform many other useful labor

saving tasks in the garden.

Wheel Position

Figure 6

The tiller is shipped with the wheels adjusted such that

the unit sits level. While 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 6.

Removing End Caps

Figure 7

The end caps are used to avoid tilled soil from

overflowing onto unwanted areas. They are removable

from the outer axle by removing the hairpin clip and

clevis pin that secures each end cap. Slide end cap off

the axle. See Figure 7.

Controlling Speed And Tilling Depth

Wheel Yoke Adjustment

Figure 8

Place wheel yoke so that the wheels are forward

(nearest point between wheels and tines) for shallow

tilling, cultivating, and transport. The forward speed will

increase. Turn yoke around (farthest point from the

tines) for deep tilling. Forward speed will decrease in

this position. See Figure 8.

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. Refer to Figure 6.

By increasing the depth of the depth stake, the forward

speed of the machine is reduced, and the working

depth is increased. 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 will permit a

working depth of about four inches. When presetting

the working depth, the handles 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. See Figure 9.

When tilling, leave approximately 8 inches of untilled

soil between the first and second tilling paths, then

make the third path between the first and second. In

some soils, the desired depth is obtained by going over

the garden two or three times. In the latter case, the

depth stake should be lowered before each succeeding

pass over the garden. Passes should be made across

the length and width of the garden alternately. Rocks
