Figure 4-2: Use one hand to guide tiller when moving forward. (b) As the tiller moves forward, relax and let the wheels pull the unit along while the tines dig. Walk behind and a little to one side of the tiller. Use a light but secure grip with one hand on the handlebars, but keep your arm loose.
Page 14
Section 4: Operation Tilling Tips Let the tiller do the work • While tilling, relax and let the wheels pull the tiller along while the tines do the digging. Walk on the side that is not yet finished (to avoid making foot- prints in the freshly tilled soil) and lightly, but securely grip the handlebar with just one hand.
Tilling Tips Clearing the tines The tines have a self-clearing action which eliminates most tangling of debris in the tines. However, occasionally dry grass, stringy stalks or tough vines may become tangled. Follow these proce- dures to help avoid tangling and to clean the tines, if necessary.
Page 16
Section 4: Operation POWER COMPOSTING Power composting simply means tilling under and burying in the soil all manner of organic matter such as crop residues, leaves, grass clippings and cover crops. This material will decompose during the non-growing season and add important natural nutrients to the soil.
