ChangingBelt RangeSpeeds

Thetiller hastwo forward belt rangespeeds for the wheelsandtines: Low andHigh. The two rangesare obtained by moving the for- ward drive belt betweentwo sets of grooves onthe forward drive pulley andthe transmission drive pulley.

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

ToChangefrom Lowto HighSpeed:

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

2.Movethe Wheel GearLever into the DIS- ENGAGEposition.

3.Removethe two nuts from the plastic belt cover on top of the transmission and removethe belt cover.

4.From beneaththe tiller, movethe for-

ward drive belt out of the transmission low speed groove (B, Figure 4-10) and into the high speed groove (D).

5.Pull upward on the belt to removeany slack and slip the belt out of the engine

drive pulley low speed groove (A, Figure4- 10) and into the high speedgroove (C).

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

6.Checkthatthe belt is withinthe forward

beltguide (E, Figures4-10 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. Besure 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.Reinstallthe plastic belt cover andse- cure it with the two nuts.

8.Put Wheel GearLeverin ENGAGEand re- connect spark plug wire before attempting to start the engine.

To Changefrom Highto LowSpeed:

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

2.Put Wheel GearLever in DISENGAGE.

3.Removethe two nuts from the plastic belt cover on top of the transmission and removethe belt cover.

4.From beneaththe 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 removeany slack and slip the belt out of the engine drive pulley highspeed groove (C,Figure4- 1O)and into the low speed groove (A).

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

6. Checkthat the belt is within the forward

belt guide (E,Figures4-10 and4-11) onthe right-side of the unit and is within the for-

ward idler (F,Figure 4-11) on the left-side. Besure that the belt is situated in the rear

grooves (A and B, Figure4-10) of the en- gine (upper) and transmission (lower) pul- leys.

7.Reinstallthe plastic belt cover andse- cure it with the two nuts.

8.Put the Wheel GearLever in ENGAGE and reconnect the spark plug wire before attempting to start the engine.
