Choosing Wheel & Tine Speeds

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 determine the combination that provides the best results. Here are some tips:

1.Advance the throttle lever so the engine has sufficient power.

2.When tilling untilled or hard earth, do not set the Depth Regulator too deep. The tiller will buck and the engine will load down.

3.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.

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 before changing the belt speeds.

Changing the belt from LOW range into HIGH range (or back again) is a matter of moving the belt from one set of pulley grooves to a second set of pulley grooves. This change is done quickly and without tools.
