4.1 Filling The Fuel Tank
WARNING
WARNING

Page 12
4.2 Motion Control Levers
Motion Control Levers in Operating Position
Motion control levers are in the operating position when they are as shown above. Left hand lever
controls the speed and direction of the LH drive wheel. Right hand lever controls the speed and
direction of the RH drive wheel.
Moving both levers forward together causes mower to travel forward in a straight line.
Moving both levers rearward together causes the mower to travel in reverse in a straight line.
To turn left while moving forward, pull back slightly on the LH lever. To turn right while moving
forward, pull back slightly on the RH lever.
To make a zero radius turn, move one lever slightly ahead of neutral and the other lever slightly
behind neutral center position.
4.3 Parking Brake
The parking brake system on the Yard Shark mower is not really a brake, but is actually a pin and
cog system that is activated every time the control levers are moved out into the neutral locked
position as shown below. It is an automatic system that sets itself when you move the levers out to
get off the mower and releases itself when you move the levers back in to start moving. If the
mower will not move or sounds like it is straining, simply move the control levers slightly forward or
backwards to release the pin.

4.4 PTO Engagement Switch
Located on RH control panel. Switch is pulled UP (“ON” position) to engage the blades.
Switch must be in the DOWN or OFF position in order to start the engine.
4.5 Choke Control
Pull choke knob UP or OUT to the choke “ON” position.
Push choke knob DOWN or IN the choke “OFF” position.
4.6 Throttle Control
Move lever forward to increase engine speed.
Move lever to the rear to idle position.
When mowing the throttle should be in the full forward (fastest) position.
4.7 Ignition Switch
Three (3) position switch. The first position is OFF, second position is ON or RUN. The third
position is the start position.
4.8 Fuel Gauge / Hour Meter
Digital display indicates amount of fuel remaining. When red light flashes, unit is very low on fuel
and should be refueled.
Refer to all items in filling the tank (Section 4.1).
The hour meter records time the key is on. Use hour meter to reco rd service intervals.
Page 14
4.9 Seat and Armrests
There are two adjustments at the front of the seat.
The knob controls the stiffness of the suspension seat. This should be adjusted to fit the
operator weight.
The lever, shown above left with an arrow, allows for fore and aft adjustment. While seated, pull
lever to the left to release seat and move seat into desired position. Make sure the latch is fully
locked so that seat is secure.
The armrest height can be adjusted with the small knobs, above right, screw out to raise armrests.
Setting the armrests at the proper height will assist you in maintaining better control of
the machine.
The other settings are located on either side of the seat backrest. The knob on the RH side adj usts
the angle of the backrest. The knob on the LH side adjusts the lumbar support. Adjust these for
your personal preference.
Page 15
4.10 Setting Mower Deck Cutting Height
While seated on the seat, push on foot lever to raise deck. The deck can now be locked in the
upper position by using the deck latch lever located on the LH side of the mower (shown below).
Move the lever to the rear to engage the deck lock. Remove pin and move to the desired position.
The decal next to the foot lever indicates the cutting height. Moving the pin one hole adjusts the
cutting height by 1/4′′.
To release deck lock, push forward on the deck latch lever while pushing forward with the
foot pedal.

4.11 Cold Engine Starting Procedure
o Be sure engine has oil to the proper level and gas in the fuel tank.
o Pull up on Choke to “ON”.
o Move throttle control about 1/3 of the way forward.
o Turn key to “START” position and hold until engine starts.
o If engine fails to start within 5 seconds, release the key, wait at least 10 seconds.
o Note: Using the starter for more than 5 seconds at a time can overheat and damage
the starter.
o Gradually push choke knob in as engine warms up.
4.12 Warm Engine Starting Procedure
Same as above but leave choke in the “OFF” position.
4.13 PTO / Blades
DANGER
The PTO switch engages the cutting blades. Be certain everyone including pets are clear of the
mower deck and the RH discharge area before engaging the PTO.
Operator must be seated before the PTO can be engaged. The motor will kill if the seat switch is
not depressed.
Move throttle to halfway position. Pull up on PTO switch to the “ON” position. Then move throttle to
full forward “FAST” position.
4.14 Deck Deflector
DANGER
Deck is equipped with a rubber deck discharge deflector.
Deflector can be pivoted upwards for clearance, for storing or transporting.
NEVER mow with the deflector in the UP position unless using an approved grass
catcher/collector.
Operating PTO creates a thrown object hazard. NEVER
operate with deflector or guards missing. Make sure
discharge chute is not pointed toward pets or bystanders.
Operating PTO creates a thrown object hazard. NEVER
operate with deflector or guards missing. Make sure
discharge chute is not pointed toward pets or bystanders.
4.15 Stopping PTO
