Operating Your Tiller

WARNING

Loading and unload- ing the tiller into a vehicle is potentially hazardous and we don’t recommend doing so unless absolutely necessary, as this could result in personal injury or property damage. However, if you must load or unload the tiller, follow the guidelines given next.

LOADING AND UNLOADING THE TILLER

•Before loading or unloading, stop the engine, wait for all parts to stop moving, disconnect the spark plug wire and let the engine and muffler cool.

•The tiller is too heavy and bulky to lift safely by one person. Two or more people should share the load.

•Use sturdy ramps and manually (engine shut off) roll the tiller into and out of the vehicle. Two or more people are needed to do this.

•The ramps must be strong enough to support the combined weight of the tiller and any handlers. The ramps should provide good traction to prevent slipping; they should have side rails to guide the tiller along the ramps; and they should have a locking device to secure them to the vehicle.

•The handlers should wear sturdy footwear that will help to prevent slipping.

•Position the loading vehicle so that the ramp angle is as flat as possible (the less incline to the ramp, the better). Turn the vehicle’s engine off and apply its parking brake.

•When going up ramps, stand in the normal operating position and push the tiller ahead of you. Have a person at each side to turn the wheels.

•When going down ramps, walk backward with the til- ler following you. Keep alert for any obstacles behind you. Position a person at each wheel to control the speed of the tiller. Never go down ramps tiller-first, as the tiller could tip forward.

•Place wooden blocks on the downhill side of the wheels if you need to stop the tiller from rolling down the ramp. Also, use the blocks to temporarily keep the tiller in place on the ramps (if necessary), and to chock the wheels in place after the tiller is in the vehicle.

•After loading the tiller, prevent it from rolling by engaging the wheels in the WHEEL DRIVE position. Chock the wheels with blocks and securely tie the tiller down.

•To create a terrace, start at the top of the slope and work down. Go back and forth across the first row as shown in Fig. 4-10.

•Each succeeding lower terrace is started by walking below the terrace you’re preparing. For added stability of the tiller, always keep the uphill wheel in the soft, newly tilled soil. Do not till the last 12” or more of the downhill outside edge of each terrace. This untilled strip helps prevents the terraces from breaking apart and washing downhill. It also provides a walking path between rows.
