engine to stop running immediately.

Safety Start Interlock System
!
WARNING
Do not bypass any safety switch. Bypassing a safety switch
can result in a serious injury or death.
The mower is equipped with a safety start interlock
system consisting of blade engagement switch, seat
switch, park brake switch, and control lever switches.
This system is an important safety feature designed to
prevent runaway or accidental entanglement.
The safety start interlock system should be checked daily
prior to operation and repaired immediately if it
malfunctions. Inspect system as follows:
1. Start mower engine per instructions in the section on
“Engine Starting”on page 18. Allow engine to warm
up to operating temperature.
2. With blade engagement switch (OFF), control levers
spread fully (OUT), and park brake (ON), slowly raise
off the seat. The engine should continue to run.
Blade Engagement Switch
1. With engine running and operator sitting on the seat,
move park brake to (OFF), pull both control levers
(IN), and then turn blade engagement switch (ON).
IMPORTANT: The starter motor will engage only if
blade engagement switch is (OFF), control levers
are (OUT), , and park brake is (ON).
Only after operator is seated and mower has been
started can park brake be moved to (OFF) and
control levers (IN) in that order or the engine will stop
running. The blade engagement switch can be pulled
(ON) only after park brake is moved to (OFF).
Park brake positioned (ON) or (OFF) does not stop
engine when becoming unseated with both control
levers (OUT) and blade engagement switch (OFF).
IMPORTANT: The operator must be on the seat
when testing switches. Contact your local Land
Pride dealer if the problem cannot be resolved.
2. Replace blade engagement switch if blades did not
run and no other cause such as damaged wiring can
be determined.
Seat Switch
1. With engine running, park brake to (OFF), control
levers (IN), and blade engagement switch (ON),
slowly raise off the seat. The engine should stop
within five seconds.
2. Replace seat safety switch if switch did not operate
properly and if no other cause can be determined.
Park Brake Switch
1. Turn blade engagement switch (OFF) and move
control levers (OUT). Park brake must be (OFF).
2. Try restarting engine. Starter motor should not turn.
3. Replace park brake switch if starter motor did turn
and no other cause can be determined.
Control Lever Switches
1. With blade engagement switch (OFF), control levers
fully (OUT), and park brake (ON), restart engine.
2. With park brake (ON) and blade engagement switch
(OFF), pull right control lever in. The engine should
stop within five seconds.
3. Replace right control lever switch if switch failed to
operate properly and no other cause can be
determined.
4. Return control arm to original setting and restart
engine.
5. With park brake (ON) and blade engagement switch
(OFF), pull left control lever in. The engine should
stop within five seconds.
6. Replace left control lever switch if switch did not
operate properly and no other cause can be
determined.
Driving the Mower
!
DANGER
Never make sudden stops or sudden reversing of travel
direction, especially when going down a slope. The steering is
designed for sensitive response. Rapid movement of control
levers could result in a reaction that can cause serious injury.
!
DANGER
Never make sudden speed changes from reverse to forward.
Always push control levers forward gently to avoid sudden
change in speed. Any sudden forward speed change can cause
the front wheels to raise off the ground resulting in loss of
control, mower damage and/or personal injury.
NOTE: When turning on soft wet turf, keep both
wheels rolling either forward or backward. Pivoting
on a stopped wheel can damage the turf.
