The ReverseClutch Control (C, Figure

3-1) controls the engagementof reverse drive to the wheels and tines. The revers-

ing feature is used for maneuveringthe tiller only- never engagethe tines in the groundwhile goingin the reverse direction.

•Use extreme caution when reversing or pulling the machine towards you. Lookbehindto avoid obstacles.

•Never attempt to till in reverse.

Failure to follow this warning could result in personal injury or property damage.

To Operatethe Reverse ClutchControl:

1.Put the Wheel GearLever in the

ENGAGEposition (seethe "WARNING" statement on previous page).

2.Stop all tiller motion by releasingthe ForwardClutch Control levers.

3.Lift upthe handlebars until the tines

clear the ground, look behindyou to avoid any obstacles, and then pull the Reverse Clutch Control knob out. The tines and wheelswill rotate in a reverse direction.

4.Releasethe ReverseClutch Control

knob to disengage (stop) the wheels and tines. All reversemotion will stop (the enginewill continue to run).

Figure3-2: DepthRegulatorLever.

The highest notch (lever all the way down) raisesthe tines approximately

1-1/2 inches off the ground. This "travel" position allows the tiller to be moved without the tines digging into the ground.

Moving the lever up increasesthe tilling depth. The lowest notch allows a tilling depth of approximately six to eight inches, depending on soil conditions.

Forbest results, always begintilling at a very shallow depthsettingand gradu- ally increasethe tilling depth. Complete

details on using the Depth Regulatorare found in the "Operation" Section of this manual.

HANDLEBAR HEIGHT ADJUSTMENT

The handlebarheight is adjustableto four different settings. Set the handlebar height to a comfortable setting, but keep in mind that the handlebarswill be lower

when the tines are engagedin the soil.

To Adjust the Handlebar Height:

F

setting and insert the raised keys on the keyedwasher into the slot. Tighten the height adjustment screw securely.

5.Retightenthe two screws at the ends of the handlebar.

detailed enginestarting and stopping instructions.

FAST- Usefor most tilling and cultivating projects.

-l_ SLOW- Usewhen idling engine or when slower tilling and cultivating speeds are needed.

•Do not attempt to till too deeply too quickly. Gradually work down to deeper tilling depths.

•Place the DepthRegulator Lever in the "travel" position before starting the engine. This position prevents the tines from touching the ground until you are ready to begin tilling.

Failure to follow this warning could result in personal injury or property damage.

DEPTH REGULATOR

The Depth Regulator lever (D, Figure 3-2) controls the tilling depth of the tines. Pull the lever straight backand slide it up or down to engagethe notched height set- tings.

Figure3-3: Handlebar height adjustment.

1.Stop the engine, wait for all parts to stop moving and then disconnect the

spark plug wire. Removethe ignition key on electric start models.
