WARNING

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

Place the Depth Regulator 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.

See your engine manual packaged with your unit for detailed instructions pertaining to starting the engine.

3.Remove Klick Pin (A, Figures 3-2 and 3-3) from wheel drive shaft (B).

4.FOR WHEEL DRIVE MODE (Figure 3-2): Slide wheel outward and align holes in wheel hub (D, Figure 3-2) and wheel shaft (B). Insert Klik pin (A) through wheel hub (C) and wheel shaft (B). Repeat with the other wheel and then remove the support from beneath the transmission.

5.FOR FREEWHEEL MODE (Figure 3-3): Slide the wheel inward and insert the Klik pin (A, Figure 3-3) only through the hole in the wheel shaft (B). Repeat for the other wheel and then remove the support from beneath the transmission.

WARNING: Before starting engine, be sure that both wheels are in WHEEL DRIVE position. See Wheels Drive Pins for instructions.

Engaging the Forward Clutch Bail or Reverse Clutch Control (if equipped) when the wheels are not in WHEEL DRIVE could allow the tines to rapidly propel the tiller forward or backward.

Failure to comply could cause loss of tiller control, property damage, or personal injury.

FORWARD CLUTCH BAIL

The Forward Clutch Bail (D, Figure 3-4) controls the engagement of forward drive to the wheels and tines.

To operate the Forward Clutch Bail:

1.Put wheels in WHEEL DRIVE position (see “WARN- ING” statement above).

2.Lift and hold the clutch bail (D, Figure 3-4) against the handlebar to start the wheels and tines rotating in a forward direction.

3.Release the clutch bail to disengage (stop) the wheels and tines (the engine will continue to run).

REVERSE CLUTCH CONTROL (Models 643B & 645A only)

The Reverse Clutch Control (E, Figure 3-4) controls the engagement of reverse drive to the wheels and tines. The reversing feature is used for maneuvering the tiller only — never engage the tines in the ground while operating in reverse.

WARNING: Use extreme caution when reversing or pulling the machine towards you. Look behind to avoid obstacles.

Never attempt to till in reverse.

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

To operate the Reverse Clutch Control:

1.Put wheels in WHEEL DRIVE position (see “WARN- ING” statement at the left).

2.Stop all tiller motion by releasing the Forward Clutch Bail.

3.Lift the handlebar until the tines clear the ground, look behind you to avoid any obstacles, and then pull the control knob (E, Figure 3-4) out. The wheels and tines will rotate in a reverse direction.

4.Release the control knob to disengage (stop) the wheels and tines (the engine will continue to run).

DEPTH REGULATOR LEVER

This lever (F, Figure 3-5) controls the tilling depth of the tines. Pull the lever back and slide it up or down to engage the notched height settings.

The “travel position” (highest notch) raises the tines approximately 1-1/2” off the ground, allowing the tiller to be moved without the tines contacting the ground. This setting should also be used when starting the engine.
