Choosing Wheel & Tine Speeds 2. The tiller has four FORWARD wheel/tine speed combinations for handling a variety of tilling tasks and gardening jobs. Experiment with the tine depth, engine speed, and wheel/tine speed to 3. determine the combination that provides the best results. Here are some tips: 1. Advance the throttle lever so the engine has sufficient power. When tilling untilled or hard earth, do not set the Depth Regulator too deep. The tiller will buck and the engine will load down. You will know your settings are ideal when the tines break-up the soil easily, the engine does not labor, and your progress is steady and smooth. See Fig. 4-5.

Figure 4-5 Changing Belt speed Your tiller has two belt-driven speed ranges - HIGH RANGE and LOW RANGE - you pick one or the other by deciding which set of pulley grooves to move the forward belt into. By moving the belt from one speed range into the other, in combination with the FAST and SLOW wheel speeds, you obtain a choice of four different forward wheel speeds and two different tine speeds. When the tiller is moving in REVERSE, the wheels are powered by a rubber reverse disc, not by the belt. Therefore, you have only two reverse speeds SLOW and FAST, as set with the Wheel Speed Lever. Fig. 4-6 shows the range of wheel and tine speeds available when using the two belt speed ranges and the FAST and SLOW selections on the Wheel Speed Lever. WARNING! To help avoid serious personal injury, stop the engine, remove the ignition key, disconnect spark plug wire and move the wire away from the spark plug and let engine and muffler cool down Available wheel and tine speeds at 3000 RPM engine speed. Belt Position Wheel Speed Lever Wheel Speed Tine Speed Low Range Slow .5 MPH 146RPM before changing the belt speeds. Low Range Fast 1.2 MPH 146RPM Changing the belt from LOW range into HIGH range (or back again) is a matter of moving the belt from one set of pulley High Range High Range Slow Fast .7 MPH 1.72 MPH 200RPM 200RPM grooves to a second set of pulley grooves. This change is done quickly and without tools. Figure 4-6 Section 5 - Operation 17
