Engage the Parking Brake
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

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 t he throttle control to midway between the SLOW
and FAST positions.
5. Turn t he 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.
