Section 4: Operation

4.When the turn is complete, shift to NEUTRAL and lower the handlebars. Move Tines/PTO Clutch Lever back to ENGAGE position and resume forward operation.

Transporting The Tiller Around Your Property

When the engine is running, the tiller’s powered wheels make moving the tiller to and from the garden easy. If the engine is not running set the Wheel Speed Lever to FREEWHEEL position to roll the tiller to another location.

WARNING

To help avoid personal injury from revolving tines, always put the Tines/PTO Clutch Lever in DISENGAGE position before transporting, loading, or unloading tiller.

1.Place the Tines/PTO Clutch Lever in DISENGAGE position.

2.Move Depth Regulator Lever down all the way into the Travel setting.

3.If using engine power, move Wheel Speed Lever to either SLOW or FAST, and use the Wheels/Tines/PTO Drive Lever to drive the wheels.

4.If the engine is stopped, move Wheel Speed Lever to FREEWHEEL, and manually push tiller.

Testing the Forward

Interlock Safety System

The Forward Interlock Safety System is designed to shut the tiller engine off immediately if you lose control and cannot stop moving FORWARD by shifting the Wheels/Tines/PTO Drive Lever into NEUTRAL. When you release both Forward Interlock Levers, they send ground to the ignition system thereby stopping the engine. Squeezing one or both levers up against the handlebars enables the ignition system; therefore, you must squeeze at least one lever whenever the Wheels/Tines/PTO Drive Lever is engaged in FORWARD.

IMPORTANT: The interlock system also prevents the engine from starting if the Wheels/Tines/PTO Drive Lever is engaged in FORWARD.

DANGER

The Forward Interlock Safety System is designed for the operator’s safety. Do not disconnect or attempt to defeat the purpose of the system. If the system malfunctions, immediately contact your local authorized dealer or the TROY-BILT Technical Service Depart- ment for assistance. Do not use the tiller or the PTO power unit until the Forward Interlock Safety System is functioning properly. Always test the system before using the tiller or PTO power unit.

How to Check the Interlock System

The Forward Interlock System has an electro-mechanical design, and so is subject to normal wear and possible mal- function. Check the system for proper operation each time prior to using the tiller or PTO power unit.

Figure 4-6: Plug and receptacle of Forward Interlock Safety System must be securely connected.

To test the Forward Interlock System:

1.Move tiller outside to level ground. Remove any obstacles.

2.Check that the Forward Interlock wire harness plug, at the bottom of the handle- bars (Figure 4-6), is securely connected to the receptacle on the top, right side of the transmission.

3.Move Wheel Speed Lever (Figure 4-2) to SLOW position and move Tines/ PTO Clutch Lever to DISENGAGE.

4.Start engine as described under Starting and Stopping the Engine, in this section. Set engine throttle lever to SLOW, and let engine warm up.

5.Squeeze and hold just one of the Forward Interlock Levers against the handlebar grip while moving the Wheels/ Tines/ PTO Drive Lever down to FORWARD (Figure 4-3). As the tiller moves forward, release the Forward Inter- lock Lever briefly. The engine should start to stall out if the interlock system is working properly. If it does start to stall, quickly squeeze the lever up against the handlebar grip, and then return the Wheels/ Tines/ PTO Drive Lever to NEUTRAL. Repeat this test to check that the engine begins to stall out when the other Forward Interlock Lever is released.

6.If the engine does not begin to shut off when either Forward Interlock lever is released, shut the engine off, remove the key (if electric start), and do not operate the tiller or PTO power unit until the system has been repaired and is func- tioning properly.

IMPORTANT: To avoid possible damage to the Forward Interlock Safety system, do not use high-pressure sprays near the wire harness receptacle or neutral plunger assembly.

Loading and Unloading the Tiller

The following provides information on tiller loading, unloading, and requirements before loading and unloading the tiller. Read the following instructions carefully before attempting to load or unload your tiller.

Before Loading or Unloading the Tiller

•Ramps must be strong enough to support the combined weight of the tiller and handlers. They should provide good traction to prevent slipping; they should have side rails to guide the tiller along the ramps; and they should have a locking device to secure them to the vehicle.

•Handlers should wear sturdy footwear that will help to prevent slipping.
