b. The tension of the deck drive belts are maintained
by a spring mechanism that adjusts for wear and
stretch.
c. Examine the belts for cuts, fraying, and excessive
wear. Replace if any of these are detected.
d. Replace the deck cover.
11. Check if deck is level. When correctly adjusted the mower
deck should be level side to side, and the front of the deck
should be approximately 1⁄4" lower than the rear of deck.
If deck needs to be leveled, refer to the Maintenance &
Adjustments section.
12. Lubricate all pivot points listed in the Maintenance &
Adjustments section.
13. Adjust the seat for operator's maximum comfort, visibility
and for maintaining complete control of the tractor.
Starting the Engine
WARNING!
This machine is equipped with a safety
interlock system designed for protection of the operator.
Do not operate the machine 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 valve and select one of the two tanks.
2. Operator must be sitting in the tractor seat with both drive
control pedals in the neutral/start position.
3. Engage the parking brake.
4. Make certain the PTO is in the disengaged (down) position.
5. Lift the choke knob into the on position.
NOTE: If the engine is warmed up, it may not be necessary
to choke the engine.
6. Move the throttle control to midway between the SLOW
and FAST positions.
7. Turn the ignition key clockwise to the START
and release it as soon as the engine starts; however, do not
crank the engine continuously for more than 10 seconds
at a time. If the engine does not start within this time, turn
the key to STOP and wait at least 30 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.
8. Once the engine starts, push the choke halfway down and
as the engine warms, push the choke all the way down.
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!
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 disengaged position.
2. Engage the parking brake.
3. Move the throttle to the SLOW
engine to idle for about one minute.
