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.

& Clevis Pins

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.

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.

For Shallow Tilling

For Deep Tilling

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
