REV B 3-6 605228
Only start the engine from the operator’s position.
3. Use choke when engine is cold, or if warm engine fails to
start within 5 seconds of cranking. Avoid flooding by
operating engine without choking as soon as possible.
4. Set throttle at approximately 1/2 open position.
5. Insert key in ignition switch and rotate full clockwise to
engage starting motor. Release key when engine starts.
IMPORTANT: The engine starter should not be operated
for periods longer than 30 seconds at a time. An interval
of at least two minutes should be allowed between such
cranking periods to protect the starter from overheating
and burning-out.
6. Perform a test to make sure the safety start interlock
system is operating properly. Refer to Safety start
interlock system section.
7. As soon as the engine begins to run, check to make
certain all engine warning lights are off. If not, stop the
engine immediately and check for the cause.
8. Allow the engine to idle a few minutes before advancing
the throttle and/or engaging the deck clutch.
Stopping the Engine
Use the following procedure to shut off the engine after
operating the equipment.
1. Place the steering control levers in the park brake
position.
2. Throttle the engine back to low idle, then disengage the
deck clutch. Refer to Mower deck operation section for
more details.
3. Let the engine run at low idle for a couple of minutes.
4. Rotate the ignition key counter-clockwise to the “OFF”
position. Remove the key from switch before leaving the
mower.
Moving the Mower with Stalled Engine
If it becomes necessary to move the machine when the engine
is inoperative, the transaxles are equipped with bypass valves.
Before moving the unit, pull up on the bypass valve rod and
slide it in the slot to the disengaged position.
The steering control levers must be placed in the neutral
position, to release the park brakes, so that the mower can be
moved. Both bypass valve rods are located at the front corners
of the engine on the engine platform. Figure 3-6
Do not tow the machine. Move it by hand or use a winch to
load on a trailer for transporting. When transporting on another
vehicle, the mower must be secured.
IMPORTANT: Always make certain the two bypass valves
are returned to their operating position before running the
mower following repairs.
ROPS (Roll Over Protection Structure)
A ROPS may minimize the chance of injury or death from
rollover.
A ROPS, when used with a seat belt, is effective in reducing
injuries during unit overturn accidents. Overturning the unit
without a ROPS or without ROPS locked in the raised position
can result in serious injury or death. Figure 3-7
The two-post ROPS can be pivoted down by removing the
right and left retaining rings (Figure 3-7), and pulling out on the
clevis pins so that the machine can operate under low hanging
tree limbs or other obstructions. Do not wear the seat belt when
the ROPS is in the lowered position. Use the ROPS in the
Allow the engine exhaust manifold to cool before engag-
ing or disengaging the bypass valves. The bypass valve
rods are located close to the exhaust system.
