Check tractor safety start interlock system daily, prior to

operation. This system is an important tractor safety feature. It should be repaired immediately if it malfunctions. The machine incorporates a separate seat switch which will stop the tractor engine when the operator is unseated for any reason while the tractor is operating. This is a safety feature designed to prevent runaway or accidental entanglement. To inspect the system:

1.The operator must be on the seat when testing the seat switch.

2.Set both control levers in the park brake position.

3.Start the engine and allow it to warm up to operating temperature.

4.With the deck clutch switch down and the control levers in the park brake position, slowly raise off of the seat.

The engine should continue to run.

5.With the deck clutch switch up and/or the control levers in the neutral position, slowly raise off of the seat. The engine should stop.

6.If the engine fails to stop when the deck clutch switch is up or one or both of the control levers is up and the operator is off the seat, check the function of the seat switch. If the seat switch is not operating properly (is not

opening or closing) and if the cause can not be determined, replace the seat switch.

If the problem can not be located, contact your Hustler Dealer.

WARNING: The safety interlock system should always function per steps 4 and 5. If it does not func- tion properly, it should be corrected immediately. Do not operate machine without properly functioning seat safety switch.

Engine starting

The tractor’s safety start interlock system is also designed to protect the operator and others from accidental injury due to unintentional engine starting. The engine starting motor will not engage until:

A.Control levers are in the park brake position.

B.Deck clutch switch is in the down (OFF) position.

WARNING: The safety interlock system must not be disconnected or bypassed. Doing so could cause the machine to operate unexpectedly resulting in personal injury.

NOTE: The operator’s seat is equipped with a separate safety switch. If for any reason the operator should become unseated when the control levers are not in the park brake posi- tion (park brake switches are disengaged) or the deck clutch switch is engaged the engine will stop.

The following steps are the correct procedures for starting the engine. If difficulty is encountered, contact the Hustler Dealer in your area.

1.Before starting tractor each day, perform daily pre- operation checking. (See Safety Start Interlock System section)

2.Make sure the control levers are in the park brake position and deck clutch switch is disengaged. Only start the engine from the operator’s position.

3.Use choke, if unit is equipped with one, when engine is cold, or if warm engine fails to start within 5 seconds of
