Figure 4-2: Use one hand to guide tiller whenmovingforward.

(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 oneside of the tiller. Usea light but secure grip with one hand on the handlebars,but keepyour arm loose. SeeFigure4-2. Let the tiller move aheadat its own pace and do not push down on the han- dlebars to try andforce the tiller to dig deeper - this takes weight off the wheels, reducestraction, and causes the tines to try and propel the tiller.

Do not push down on the handlebars to try to make the tiller till more deeply. This preventsthe wheels from holding the tiller back and can allow the tines to rapidly propel the tiller forward, which could result in loss of control, propertydamage, or personal injury.

5.For reverse motion of the wheelsand tines:

(a)Look behind andexercise caution when operating in reverse. Do not till while in reverse.

(a)Practiceturning the tiller in a level, open area. Bevery careful to keep your feet and legs awayfrom the tines.

(b)To makea turn, reducethe engine speed andthen lift the handlebars until the engine and tines are bal- anced over the wheels (Figure 4-4).

(c)With the tiller balanced,push side-

ways on the handlebarto move the tiller in the direction of the turn

(Figure4-5). After completing the turn, slowly lower the tines into the soil and increasethe enginespeed.
