Oil Pressure Light
Refer to Figure 2-2:
This light comes on when the ignition switch is placed in
the RUN position and stays lit until the engine is running
and a safe oil pressure is developed. If light comes on
during operation, shut engine off immediately, locate and
correct the problem.
Electronic Hour Meter
Refer to Figure 2-7
The hour meter is located on the right side behind the seat
and registers in 1/10 hour increments up to 9,999.9 total

the accumulative time while the ignition key is switched to
the RUN position and the operator is on the seat.

Safety Start Interlock System
The mower is equipped with a safety start interlock system
consisting of park brake switches, seat switch and blade
engagement switch.
Check mower safety start interlock system each day prior
to operation. This system is an important mower safety
feature and should be repaired immediately if it is
malfunctioning. The mower incorporates a separate seat
switch which will stop the engine whenever the operator is
unseated while the mower is moving or the blades are
engaged. This safety feature is designed to prevent
runaway or accidental entanglement. Inspect the system
as follows:
1. The operator must be on the seat when testing the
seat switch.
2. Set both control levers in the park brake position.
3. Start the engine and allow it to warm up to operating
temperature.
4. A person should be able to slowly raise off the seat
without the engine stopping if the blade engagement
switch is down and the control levers are in the park
brake position.
5. The engine should stop within two seconds if a person
raises slowly off the seat and either the blade
engagement switch is up or the control levers are in
neutral position.
6. Check the function of the seat switch If the engine fails
to stop when the blade engagement switch is up or if
one or both of the control levers are in and the
operator is off the seat. Replace the seat switch If the
seat switch is not operating properly (i.e. switch is not
opening and/or closing).
If the problem cannot be located, contact your Land Pride
Dealer.
!
WARNING!
The safety interlock system should always function per steps 4
and 5. If it does not function properly, it should be corrected
immediately. Do not operate machine without a properly
functioning seat safety switch.
Engine Starting
The Razor Pro safety start interlock system is also
designed to protect the operator and others from
accidental injury due to unintentional engine starting. The
engine starting motor will not engage until the following
two criteria are meet:
•
Control levers are in the brake position.
•
Blade engagement switch is in the down (OFF) position.
!
WARNING!
The safety interlock system must not be disconnected or
bypassed.
The following steps are the correct procedures for starting
the engine. If difficulty is encountered, contact the Land
Pride Dealer in your area.
1. Before starting mower each day, perform daily
pre-operation checking. (See “Safety Start Interlock
System” on this page.)
2. Make sure the control levers are in the brake position
and blade engagement switch is disengaged.
3. Set throttle at approximately 1/2 open position.
4. Insert key in ignition switch and rotate clockwise to
engage starting motor. Release key when engine
starts.
NOTE: The operator’s seat is equipped with a
separate safety switch. If for any reason the operator
should become unseated when the neutral switches
are disengaged or the blade engagement switch is
engaged the engine will stop.
NOTE: Use choke position when engine is cold, or if
warm engine fails to start within 5 seconds of
cranking. Avoid flooding and operate engine without
choking as soon as possible.
