Clearing Obstacles
1.
If it is necessary to drive over an obstruction, stop
mower, turn off blades, and raise deck fully up to
transport position.
2.
Move forward slowly to make certain deck clears the
obstruction.
3.
Lower deck to cutting height after mower has passed
over obstruction. Engage blades and continue
mowing.
IMPORTANT: Always disengage blades before
changing deck cutting height.
IMPORTANT: The deck must be leveled before
setting deck cutting height. See “Deck Cutting Height
And Leveling” instructions on page 25.
NOTE: Cutting height provided on deck height
indicator (#4) is from 1" to 4 1/2" in 1/2" increments.

IMPORTANT: It is best to mow around obstructions;
not over them. Beware, the front of the deck can
clear an obstacle and still make contact by high
centering on the obstacle. Mowing over obstacles
that make contact with the deck can bend/break
mower deck, mower blades, and blade spindles.
Engine Starting
The safety start interlock system is designed to prevent
runaway or accidental entanglement.
The following steps are correct procedures for starting
the engine. If difficulty is encountered, contact your local
Land Pride Dealer.
1.
Before starting the engine, make sure:
a. Blade engagement switch is (OFF).
b. Both control levers are positioned (OUT).
c. Park brake is (ON).
2.
Set speed control to approximately 1/2 open throttle.
3.
Insert key into ignition switch and rotate clockwise to
engage starter motor. Release key when engine
starts.
4.
Perform test to make sure safety start interlock
system is operating properly. Refer to “Safety Start
Interlock System” on Page 16.
5.
As soon as engine begins to run, check to make
certain oil warning light is off. If not, stop engine
immediately and check for the cause. Refer to
“Troubleshooting” on page 50.
6.
Allow engine to idle a few minutes to warm up before
operating the mower.
Engine Shut-Down Sequence
It is always best to go through proper shut-down
sequence before turning ignition switch key off. Not
following this sequence in the correct order will cause the
engine to stop running immediately.
1.
Shut blade engagement switch (OFF).
2.
Move both control levers to neutral and (OUT).
3.
Throttle engine back to a low idle and wait for one
minute to allow accumulated raw fuel to escape
muffler during engine slow down.
4.
Position park brake (ON). (Pull up on lever until it
stops.)
5.
Rotate ignition key counter-clockwise to (OFF).
6.
Remove key from ignition switch.
IMPORTANT: The starter motor will engage only if
the blade engagement switch is (OFF), control
levers are (OUT) and park brake is (ON).
IMPORTANT: Use choke when engine is cold or if
warm and engine fails to start after 5 seconds of
cranking. Avoid engine flooding by pushing choke
control knob to (OFF) as soon as possible.
IMPORTANT: The engine starter should not be
operated for periods longer then 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 burn-out.
