Safety Checks
Functional Tests
1. Check for loose bolts, screws, nuts, etc.
2. Start the engine and check all controls for proper
operation: motion control levers, engine speed and
choke cables, electric PTO clutch, cutting height
adjustment lever, etc.
3. Stop the engine and check for fluid leaks: oil, gaso-
line, or transmission oil.
4. If any control fails to operate properly during testing or
seems to be out of adjustment, check and readjust it
according to the following Adjustments section.
4. Turn the key to OFF to end the demonstration.
Mower Blade Stopping Check
Mower blades and mower drive belt should come to a
complete stop within five seconds after the electric clutch
switch is turned off.
With the motion control levers locked into their neutral
locked positions, the electric clutch switch disengaged,
and an operator in the seat, start the engine. Run at full
speed. Engage the electric PTO clutch switch and wait
several seconds. Disengage electric clutch switch and
check the time it takes for the mower drive belt to stop. If
the mower drive belt does not stop within five seconds,
adjust the PTO clutch according to the instructions in the
Electric Clutch Adjustment section.
Seat Switch Connection
Check that the seat switch wire harness (C, Figure 7) is
connected to the seat switch.
Burnish PTO Clutch
1. Select a safe area to operate the mower deck. With
the motion control levers locked into their neutral
locked positions, the PTO switch disengaged, and an
operator in the seat, start the engine. Run the engine
at full speed.
2. Engage the PTO switch and run the deck for fifteen
seconds. Disengage the PTO switch and wait for the
mower drive belt to stop.
3. Repeat step 2 above ten times, and then re-check the
mower blade stopping time. (Stopping time must be
five seconds or less.)
WARNING
Disengage the PTO, stop the engine, move both
motion control levers into their neutral locked
positions, and wait for moving parts to stop
before leaving operator's position for any reason.
If the unit does not pass the test, do not operate
it. Under no circumstance should you attempt to
defeat the purpose of the safety system.
