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. Operator must be sitting in the tractor seat.
2. Engage the parking brake. Refer to Fig. 5-1.
3. Make certain the PTO switch is in the disengaged (down)
position. Refer to Fig. 5-1.
4. Move the choke control or throttle/choke control into the
full choke position.
NOTE: If the engine is warmed up, it may not be necessary
to place the choke or throttle/choke control in the choke
position.
5. Move the throttle control to midway between its slow and
fast positions on models with a separate choke control.
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 5 seconds at
a time. If the engine does not start within this time, turn
the key to the stop
position and wait at least 15 seconds
to allow the engine’s starter motor to cool. Try again after
waiting. If after a few attempts the engine fails to start, do
not keep trying to start it with the choke closed as this will
cause flooding and make starting more difficult.
7. As the engine warms up, gradually pull the throttle/choke
control lever rearward past the choke detent position or
slowly disengage the choke on models with a separate
choke. Do not use the choke position to enrich the fuel
mixture, except as necessary to start the engine.
8. Allow the engine to run for a few minutes at mid throttle
before putting the engine under load.
9. Observe the hour meter/indicator panel. If the battery
indicator light or oil pressure light come on, immediately
stop the engine. Have the tractor inspected by your Cub
Cadet dealer.
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.
2. Use fresh winter grade fuel. Winter grade gasoline has
higher volatility to improve starting. Do not use gasoline
left over from summer.
3. Follow the previous instruction for Starting the Engine.
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. Disengage the PTO..
2. Move the RH and LH drive control levers fully outward in
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 stop 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.
Practice Operation (Initial Use)
Operating a zero-turn tractor is not like operating a conventional
type riding tractor. Although and because a zero turn tractor is
more maneuverable, getting used to operating the control levers
takes some practice.
