Starting the Engine

Warning! This tractor is equipped with a safety interlock system designed for the protection of the operator. Do not operate the tractor if any part of the interlock system is malfunctioning. Periodically check the functions of the interlock system for proper operation.

Warning! For personal safety, the operator must be sitting in the tractor seat when starting the engine.

1.Open the fuel supply valve.

2.Operator must be sitting in the tractor seat with the speed control pedals in the neutral/start position.

3.Engage the parking brake. See Fig. 5-1.

Engage the Parking Brake

Figure 5-1

4.Make certain the PTO switch is in the disengaged (down) position.

5.Set the throttle in the slow position (slightly faster for cold temperatures).

6.Turn the ignition key clockwise to the “START” position and release it as soon as the engine starts; however, do not crank the engine continuously for more than 15 seconds at a time. If the engine does not start within this time, turn the key to “OFF” and wait at least 30 seconds to allow the engine’s starter motor to cool.

Cold Weather Starting

When starting the engine at temperatures near or below freezing, ensure the correct viscosity motor oil is used in the engine and the battery is fully charged. Start the engine as follows:

1.Be sure the battery is in good condition. A warm battery has much more starting capacity than a cold battery.

NOTE: Battery should provide 11.0 VDC during cranking for shut-off valve to function correctly. This also provides desired engine cranking speed.

2.Set the throttle slightly faster than the slow position.

3.Crank engine for about 5 seconds and stop.

4.Wait about 10 seconds, then crank for 15 seconds or until it starts running.

5.Repeat if necessary.

Using Jumper Cables To Start Engine

Warning! Batteries contain sulfuric acid and produce explosive gasses. Make certain the area is well ventilated, wear gloves and eye protection, and avoid sparks or flames near the battery.

If the battery charge is not sufficient to crank the engine, recharge the battery. If a battery charger is unavailable and the tractor must be started, the aid of a booster battery will be necessary. Connect the booster battery as follows:

1.Connect the end of one cable to the disabled tractor battery’s positive terminal; then connect the other end of that cable to the booster battery’s positive terminal.

2.Connect one end of the other cable to the booster battery’s negative terminal; then connect the other end of that cable to the frame of the disabled tractor, as far from the battery as possible.

3.Start the disabled tractor following the normal starting instructions previously provided; then disconnect the jumper cables in the exact reverse order of their connection.

4.Have the tractor’s electrical system checked and repaired as soon as possible to eliminate the need for jump starting.

Stopping the Engine

1.Place the PTO switch in the “OFF” position.

2.Move the speed control pedals to the neutral position.

3.Engage the parking brake.

4.Move the throttle control to midway between the SLOW and FAST positions.

5.Turn the ignition key to the “OFF” position and remove the key from the ignition switch.

NOTE: Always remove the key from the ignition switch to prevent accidental starting or battery discharge if the equipment is left unattended.

6.Close the fuel supply valve.
