Safety Start Interlock System
The mower is equipped with a safety start interlock
system consisting of blade engagement switch, seat
switch, park brake switch, relays and control lever
switches. This 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:
Start mower engine per instructions in the section on
“Engine Starting” on page 17. Allow engine to warm up to
operating temperature.
Blade Engagement Switch
1.
With engine running and operator sitting on the seat,
move park brake down to (OFF) and turn blade
engagement switch (ON).
2.
Replace blade engagement switch if blades did not
run and no other cause can be determined such as
the wiring came unplugged from the electric clutch or
the wiring is damaged.
Seat Switch
1.
Turn blade engagement switch (OFF), spread control
levers fully (OUT) and pull park brake up to (ON),
slowly raise off the seat. The engine should continue
to run.
2.
Turn blade engagement switch (ON), slowly raise off
the seat. The engine should stop within five seconds.
3.
Replace seat safety switch if switch did not operate
properly and no other cause can be determined.
Park Brake Switch
1.
Turn blade engagement switch (OFF), move control
levers (OUT), turn engine switch (OFF) and move
park brake lever down to (OFF).
2.
With park brake lever (OFF), Try restarting the
engine. The starter motor should not turn.
3.
Replace park brake switch if starter motor did turn
and no other cause can be determined.
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 the switches. Contact your local Land
Pride Dealer if the problem cannot be resolved.
Control Lever Switches
1.
With blade engagement switch (OFF), control levers
spread 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 if no other cause can be
determined.
4.

engine.
5.
With park brake (ON) and blade engagement switch
(OFF), pull left control lever in. The engine should
stop within five seconds.

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 in either direction 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.
To Start and Increase Speed
Refer to Figure 2-7 on page 19:
After starting the engine, release park brake and engage
control levers by moving handles fully (IN). This makes
the levers ready for steering while traveling.
Moving control levers an equal distance away from
neutral will increase travel speed.
•
Start forward travel by gently pushing on the control
levers. The further forward the control levers are
pushed the faster the travel speed.
•
Start backing up by gently pulling on the control levers.
The further back the control levers are pulled the faster
the travel speed.
