Stopping the Tiller and Engine

1.To stop the wheels and tines, release the Forward Clutch levers or the Reverse Clutch Control (whichever is engaged).

2.To stop the engine, move the Engine Throttle Lever to STOP.

3.If the engine is equipped with a fuel shut- off valve, close the valve as instructed in the Engine Owner’s Manual.

WARNING: Before

changing belt speeds, stop engine, wait for all parts to stop moving, let engine cool and disconnect spark plug wire. Failure to follow these instructions could result in personal injury.

Changing Belt Range Speeds

The tiller has two forward belt range speeds for the wheels and tines: Low and High. The two ranges are obtained by moving the for- ward drive belt between two sets of grooves on the forward drive pulley and the transmission drive pulley.

NOTE: The High speed belt range is recom- mended for all tilling purposes. The Low speed belt range will operate the tines and wheels at a slower forward speed, which may be suitable in some conditions (such as tilling in very hard ground).

To Change from Low to High Speed:

6.Check that the belt is within the forward belt guide (E, Figures 4-10 and 4-11) on the right-side of the unit and is within the for- ward idler (F, Figure 4-11) on the left-side. Be sure that the belt is situated in the center grooves (C and D, Figure 4-10) of the en- gine (upper) and transmission (lower) pul- leys.

7.Reinstall the plastic belt cover and se- cure it with the two nuts.

8. Put Wheel Gear Lever in ENGAGE and re- connect spark plug wire before attempting to start the engine.

To Change from High to Low Speed:

1.Stop the engine, allow it to cool, and dis- connect the spark plug wire.

2.Put Wheel Gear Lever in DISENGAGE.

3.Remove the two nuts from the plastic belt cover on top of the transmission and remove the belt cover.

4.From beneath the tiller, move the for- ward drive belt out of the transmission pul- ley high speed groove (D, Figure 4-10) and into the low speed groove (B).

5.Pull upward on the belt to remove any slack and slip the belt out of the engine drive pulley high speed groove (C, Figure 4- 10) and into the low speed groove (A).

NOTE: If the belt is difficult to move, pull on the engine start rope while pushing the belt with your finger (engine drive pulley will turn as start rope is pulled).
