Section 4: Operation 4. Go to right side of tiller and finish seating the belt. WARNING The HIGH speed belt range position combined with a FAST wheel speed setting propels the tiller at the fastest pace. Reduce the engine throttle speed when starting out to help avoid personal injury or property damage if using this speed combination. 3. Kneel on left side of tiller. To create belt slack, reach over to right side of the pulleys and push in at the center of the belt with a finger.
Section 4: Operation TABLE 2-4: WHEEL SPEED AND BELT RANGE SELECTION GUIDE IMPORTANT — For correct wheel speed and belt range choices when using attachments or accessories other than tines, read the Owner/Operator Manual provided with the attachment or accessory. SLOW GEAR, LOW BELT RANGE SLOW GEAR, HIGH BELT RANGE FAST GEAR, LOW BELT RANGE For: • Tilling in sod. • Tilling in hard clay. • Tilling under standing cornstalks in tough soil conditions. • Tilling under cover crops. • Preparing a deep seedbed.
Section 4: Operation Avoid making footprints Tilling Tips & Techniques When possible, walk on the untilled side of the unit to avoid making footprints in the freshly tilled soil (Figure 4-4). Footprints cause soil compaction that can hamper root penetration and contribute to soil erosion. They can also “plant” unwanted weed seeds back into the newly tilled soil.
Section 4: Operation Tilling Tips & Techniques Clearing the tines The tines have a self-clearing action which helps to eliminate most tangling of debris. However, occasionally dry grass, stringy stalks or tough vines may become tangled. Follow these procedures to help avoid tangling and to clear the tines, if necessary. WARNING Before clearing the tines by hand, stop the engine, allow all moving parts to stop and disconnect the spark plug wire.
Section 4: Operation Tilling Tips & Techniques POWER COMPOSTING Power composting 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. WARNING When power composting, do not keep the Depth Regulator Lever at a deep setting if the tiller jumps or bucks.
