the watchful care of a responsible adult other
than the operator.
• Be alert and turn machine off if a child enters
the area.
• Before and while backing, look behind and
down for small children.
• Never carry children, even with the blades
shut off. They may fall off and be seriously
injured or interfere with safe machine
operation. Children who have been given
rides in the past may suddenly appear in the
mowing area for another ride and be run over
or backed over by the machine.
• Never allow children to operate the machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects that
may block your view of a child.

CONTROLS
1. Parking Brake
IMPORTANT INFORMATION
The machine must stand absolutely still
when applying the parking brake. Always
set the parking brake before dismounting.
Release the parking brake before moving
the mower.
The parking brake is found on the left of the machine.
Pull the lever backward to activate the brake and
forward to release it.
2. Steering Control Levers
The machine’s speed and direction are continuously
variable using the two steering controls. The steering
controls can be moved forward or backward about a
neutral position. Furthermore, there is a neutral position, which is locked if the steering controls are moved
outward.
When both controls are in the neutral position (N), the
machine stands still.
By moving both controls an equal amount forward or
backward, the machine moves in a straight line forward
or backward respectively.
In order, for example, to turn right while moving
forward, move the right control towards the neutral
position. The rotation of the right wheel is reduced and
the machine turns to the right.
Zero turn can be achieved by moving one control
backward (behind the neutral position) and carefully
moving the other steering control forward from its
neutral position. The rotation direction when zero
turning is determined by which steering control is
moved backward behind the neutral position. If the left
steering control is pulled backward, the machine turns
to the left. Use extra care when using this maneuver.
If the steering controls are in uneven positions when
standing still or do not fit in the slots for moving the
controls outward, they can be adjusted.

fuels (called gasohol, ethanol or methanol)
can attract moisture which leads to
separation and formation of acids during
storage. Acidic gas can damage the fuel
system of an engine while in storage. To
avoid engine problems, the fuel system
should be emptied before storage of 30
days or longer. Drain the gas tank, start the
engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel the
next season. See Storage Instructions for
additional information. Never use engine or
carburetor cleaners in the fuel tank or
permanent damage may occur.
Fill to bottom of filler neck. Do
not overfill. Wipe off any spilled
oil or fuel. Do not store, spill or
use gasoline near an open
flame.
When operating in temperatures below 32° F. (0° C.),
use fresh, clean winter grade gasoline to help insure
good cold weather starting.

11. Throttle Control
The throttle control regulates the engine speed and
thereby the rate of rotation of the blades, assuming the
blade switch is pulled out, see Engaging the Mower
Deck.
In order to increase or decrease the engine speed, the
control is moved forward or backward respectively.
Avoid idling the engine for long periods, as there is a
risk of fouling the spark plugs.
USE FULL THROTTLE WHEN MOWING, for best
mower performance and battery charging.
12. Blade switch
In order to engage the mower deck, pull the knob out;
the mower blades are disengaged when the knob is
depressed.

13. Cutting height pedal
The cutting deck height is obtained by pressing the foot
pedal lift arm forward and releasing the transport latch.
Then lower the deck to the preset height. To raise the
deck push forward on the foot pedal lift arm until the
transport latch locks. The cutting height range is from 1
1/2" (38 mm) to 4 1/2"
(114 mm) in 1/4" (6.4 mm) increments. The heights are
measured from the ground up to the blade tip with the
engine not running.
To change cutting heights move the pin on the cutting
height plates to the desired height of cut.

IMPORTANT INFORMATION
Always use the high position to transport.
IMPORTANT INFORMATION
In order to obtain an even cutting height it
is important that the air pressure in all four
tires is the same 15 psi (1 bar).
Accessories
For mulching, there is a BioClip attachment available.
This is mounted underneath the mower deck and
consists of control plates and BioClip blades.

OPERATION
Operation
Read “Safety Instructions” section and following pages, if you are unfamiliar with the machine.
Training
Zero turn mowers are far more maneuverable than typical riding mowers due to their unique steering capabilities.
We suggest that this section be reviewed in its entirety prior to attempting to move the mower under its own power.
Additionally, we suggest when first operating the mower, use a reduced throttle speed and reduced ground speed
by NOT moving control levers to the furthest forward or reverse positions during initial operation, or until operator
becomes comfortable with controls. We also suggest first time users, or new users to Zero Turn mowers to
become familiar with the mower’s movement on a hard surface, such as concrete or blacktop PRIOR to attempting
to operate on turf. Until operator becomes comfortable with mower controls and zero turning capability, they may
damage turf due to overly aggressive maneuvers.
To move forward and backward
The direction and speed of the mower’s movements is effected by the movement of the control lever(s) on each
side of mower. The left control lever controls the left wheel. The right control lever controls the right wheel.
IMPORTANT INFORMATION
When control levers are in the reverse
position they return to neutral when
released. This may cause the mower to
suddenly stop.
First time users should push mower (see “Moving by Hand” in the “Operation” section) to an open, flat area,
without other people or vehicles/obstacles nearby. In order to move unit under its own power, the operator must be
in the seat, start engine (see “Before Starting” in “Operation” section), adjust engine speed to idle, disengage
parking brake, do not engage blades at this time, rotate control levers inward. As long as the control levers have
not been moved forward or backwards, mower will not move. Slowly move both control levers forward slightly. This
will allow mower to start moving forward in a straight line. Pull back on control levers to the neutral position and
mower should stop moving. Pull back slightly on control levers, this will allow mower to start moving backwards.
Push forward on control levers to the neutral position and mower should stop moving.
To turn to the right
While moving in a forward direction, pull the right lever back towards the neutral position while maintaining the
position of the left lever, this will slow the rotation of the right wheel and cause the machine to turn in that direction.
To turn to the left
While moving in a forward direction pull the left lever back towards the neutral position while maintaining the
position of the right lever, this will slow the rotation of the left wheel and cause the machine to turn in that direction.
To zero turn
While moving in a forward direction, first pull both control levers back until the mower stops or slows dramatically.
Then by alternating one lever slightly to the forward position and the other in the reverse position.
