Operating Your Tiller

Using Your Tiller

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

Wheel Position

The tiller is shipped with the wheels adjusted so that the unit sits level. The wheels need to be adjusted to meet your tilling needs before operation. This adjustment is made by removing the clevis pin from the wheel yoke and raising the wheels to the desired height. See Figure 4–3.

WARNING

Refer to the engine manual for detailed instructions pertaining to the engine controls.

Figure 4–3: Wheel and depth stake positioning.

Figure 4–4: Wheel and Yoke forward for shallow tilling.

Figure 4–5: Wheel and Yoke back for deeper tilling.

Tilling Depth and Wheel Yoke Adjustment

Placement of wheel yoke will effect depth of tilling.

Yoke Forward

Place the wheel yoke so that wheels are forward (nearest to tines) for shallow tilling, cultivating and transport. See Figure 4–4.

Yoke to Back

Place the wheel yoke so that wheels are toward rear (closest to depth stake) for deep tilling and cultivating. See Figure 4–5.

Depth Stake

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. See Figure 4– 6.

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 and

Figure 4–6: Pivot depth stake for transportation.

Storing the Tiller

To transport and store the tiller move the throttle to the stop position. Pivot the depth stake away from ground up between wheels. See Figure 4-6.

Tilling Procedure

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, Figure 4–7. In some soils, the desired depth is obtained the first time over the garden. In other soils, the desired depth is obtained by going over the garden two or three times. Passes should be made across the length and width of the garden alternately. Rocks which are turned up should be removed from the garden area.

With the outer tines installed, the working width of the machine is 24 inches. This width may be expanded to 26 inches by removing the clevis and cotter pins, sliding each outer tine outward away from the center of the unit and resecuring the pins in the holes provided. See Figure 4–8.

Operating

Your Tiller

Figure 4–7: Recommended tiller paths.

Removing End Caps

The end cap, which is used to avoid tilled soil from overflowing onto unwanted areas, are removable from the axle. Remove the hairpin clip and clevis pin that secure each end cap and slide the end caps off the axle. See Figure 4–9.

Cultivating

For cultivating, a two to three inch depth is desirable. The tine width can be reduced to 13 inches by removing the outer tines completely from the tiller. See figure 4–8. 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. Figure 4–10.

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

WARNING

Disconnect the spark plug wire and ground it against the engine before performing any repairs or maintenance.

WARNING: Disconnect the spark plug wire and ground it against the engine before performing any repairs.

Engine

Refer to the separate engine manual for engine maintenance instructions.

Maintain engine oil as instructed in the separate engine manual packed with your unit. Read and follow instructions carefully.

Service air cleaner every ten hours under normal conditions. Clean every hour under extremely dusty conditions. Poor engine performance and flooding usually indicates that the air cleaner should be serviced. To service the air cleaner, refer to the separate engine manual packed with your unit.

IMPORTANT: Never run your engine without air cleaner completely assembled.

The spark plug should be cleaned and the gap reset every 25 hours of engine operation. Spark plug replacement is recommended at the start of each tiller season; check engine manual for correct plug type and gap specification.

Clean the engine regularly with a cloth or brush. Keep the cooling system (blower housing area) clean to permit proper air circulation which is essential to engine performance and life. Be certain to remove all dirt and combustible debris from muffler area.

Lubrication

Pivot Points

Remove the belt cover and lubricate all pivot points and linkages at least once a season with light oil. Keep belts free of lubrication.

Tine Shafts

Remove tine assemblies and lubricate the tine shafts at least once a season.

Wheel Shafts

Remove wheel assemblies and lubricate the axle shafts at least once a season.

Chain Drive

The chain drive is pre-lubricated and sealed at factory.

Cleaning Tine Area

Clean underside of the tine shield after each use. The dirt washes off the tines easier if rinsed off immediately instead of after it dries. Always towel dry the tiller afterwards and apply a light coat of oil or silicone to prevent rusting or water damage.

IMPORTANT: Never use a “pressure washer” to clean your tiller. Water can penetrate tight areas of the tiller and its chain case and cause serious damage to unit.
