2.Engage safety start interlock system, buckle seat belt if tractor has seat belt.

3.Set parking brake.

4.Set throttle at approximately 1/3 OPEN position.

5.4200 & 4400 — Rotate key switch counterclockwise to PRE-HEAT; hold this position for 15 seconds when temperature is above freezing, or for 30 seconds when temperature is below freezing. This operation is not necessary when restarting a warm engine.

4420 & 4600 — Rotate key switch counterclockwise to PRE-HEAT; hold this position until glow plug light goes off. This is necessary only when the temperature is below 50° F. This operation is not necessary when restarting a warm engine.

Shown below are the standard preheating times for various temperatures. This operation, however, is not required when the engine is warmed up.

Failure to follow these recommendations can lead to premature failure of the starter motor and the fuel shut-off solenoid.

NOTICE: Ether, or other starting fluids, must never be used as a starting aid with this engine. Warranty will be denied when engine damage results from such use.

6.Rotate key switch full clockwise to START position, release key immediately after engine starts.

NOTE: If the engine does not start 10 seconds after the starter switch is set at “Start”, wait for another 30 seconds and then start the engine starting sequence over again. Do not allow the starter motor to run continuously for more than 20 seconds.

7.Check to make sure the engine oil pressure and alternator warning lights are off. If not, stop engine immediately and check for the cause.

8.Allow the engine to idle a few minutes before advancing the throttle or engaging the hydraulic pump. This allows the hydraulic oil to warm up for easier system circulation.

9.Stop the engine by disengaging drive clutch and throttle back to low idle for a couple of minutes; move steering control levers to neutral, engage neutral lock levers; then rotate ignition key counterclockwise to the OFF position. Remove the key from switch before leaving the tractor and set parking brake.

10.If the machine is allowed to run out of fuel, bleeding the fuel system will be required before restarting the

engine. Refer to the Maintenance & Adjustment - Fuel System section of this manual.

WARNING: Excessive starter cranking after running out of fuel and not following proper fuel system bleeding will lead to premature failure of the starter motor and/or the fuel shut-off solenoid.

Models 4300 and 4500:

1.Before starting the tractor each day, perform daily preoperation checking.

2.Your Hustler tractor incorporates a safety interlock system. Designed to protect the operator and others from accidental injury, this system prevents unintentional engine starting.

The engine starter will not engage until:

A.Steering control lever front and rear neutral locks are set.

B.PTO clutch switch is in the “OFF” position.

WARNING: The safety interlock system should not be disconnected or bypassed.

NOTE: The operator’s seat is equipped with a separate safety switch. If for any reason the operator should become unseated when the neutral lock is disengaged or the PTO switch in the “ON” position, this switch will open and engine will stop.

3.Disengage the hydraulic clutch lever to lessen drag on the starter motor, particularly when oil is cold.

4.Advance throttle to approximately 1/4 open slot.

5.Insert key in ignition switch and rotate full clockwise to engage starting motor. Release key when engine fires.

NOTE: Continuous cranking for longer than 20 seconds may damage the starter motor. After continuous cranking for 20 seconds, wait two minutes before engaging starting motor again.
