4. By pass linkages
When pushing or pulling the mower, be sure 
to engage the IZT (Integraded Zeroturn 
Transaxle) bypass linkages. The IZT bypass 
linkages are located on the rear of the frame, 
below the rear engine guard.
• Raise the deck into the highest cutting 
position.
• Pull the IZT bypass linkages out and into 
the slots and release so that it is held in 
the bypass position.
• To reengage the IZT’s to drive, reverse 
the above procedure.

5. Refueling
The machine has one fuel tank, just behind 
the seat. The tank capacity is 3 gallons 
(11.4 liters).
The engine will run on a minimum of 
85-octane unleaded gasoline (no oil mix). 
Environmentally adapted alkylate gasoline 
can be used. See also Technical Data 
concerning ethanol fuel. Methanol fuel is not 
allowed.
When operating in temperatures below 32° F. 
(0° C.), use fresh, clean winter grade gasoline 
to help insure good cold weather starting.
6. Blade switch
In order to engage the mower deck, pull the 
knob out; the mower blades are disengaged 
when the knob is depressed.
8011-752
Fuel tank
IMPORTANT INFORMATION
Experience indicates that alcohol 
blended 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.
WARNING!
Gasoline is highly flammable. 
Observe caution and fill the 
tank outdoors 
(see the safety rules).
WARNING!
The engine and the exhaust 
system, become very hot 
during operation.
Risk for burns if touched.
Allow engine and exhaust 
system to cool at least two (2) 
minutes before refueling.

WARNING!
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.

7. Ignition Switch
The ignition key is placed on the driver’s 
panel and is used to start and stop the 
engine.
8. Choke Control
The choke mode is used for cold starts in order 
to provide the engine with a richer fuel mixture.
The Throttle control is equipped with a choke 
detent. Pressing the throttle control all of the 
way forward will choke the engine. For full 
throttle, press throttle control forward until 
you feel the choke detent.
9. 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.
Avoid idling the engine for long periods, as 
there is a risk of fouling the spark plug.
USE FULL THROTTLE WHEN MOWING, for 
best mower performance and battery 
charging.

It will flash CHG OIL (Change Oil) at 50 hour 
intervals. The flash duration is one hour

12. Cutting height pedal
The deck cutting height is obtained by 
pressing the foot pedal forward to lift the 
deck. To lower the deck, you apply pressure 
to the top side of the foot pedal and allow it to 
pivot while allowing the lift arm to rotate to the 
rear of the unit. To stop in a desired cutting 
position, rotate the foot pedal down into the 
notch in the height plate. The cutting height 
range is from 1 1/2 (38 mm) to 5 (127 mm) 
in 1/2 (13 mm) increments. The heights are 
measured from the ground up to the blade tip 
with the engine not running 
.
Accessories
For mulching, there is a BioClip attachment 
available. This is mounted underneath the 
mower deck and consists of discharge cover 
and blades.

OPERATION
Operation
Read Safety Instructions section and following pages, if you are unfamiliar with the machine.
Training
Zero turn mowers are far more manueverable than typical riding mowers due to their unique steering 
capabilities. 
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 ZeroTurn 
mowers to become familiar with the mowers 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 over aggressive maneuvers.
To move forward and backward
The direction and speed of the mowers 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.
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 near by. 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.IMPORTANT INFORMATION
When control levers are in the reverse 
position they return to neutral when 
released. This may cause the mower to 
suddenly stop.

Engine exhaust and certain 
vehicle components contain or 
emit chemicals considered to 
cause cancer, birth defects, or 
other reproductive system 
damage. The engine exhaust 
contains carbon monoxide, 
which is an odorless, 
colorless, poisonous gas. Do 
not use the machine in 
enclosed spaces.

OPERATION
To start an engine with a weak 
battery
If your battery is too weak to start the engine, 
it should be recharged. (See Battery in the 
Maintenance Section.
If “jumper cables” are used for emergency 
starting, follow this procedure:
To attach jumper cables
• Connect each end of the RED cable to 
the POSITIVE (+) terminal on each 
battery, taking care not to short against 
chassis.
• Connect one end of the BLACK cable to 
the NEGATIVE (-) terminal of the fully 
charged battery.
• Connect the other end of the BLACK 
cable to a good CHASSIS GROUND on 
the mower with the discharged battery, 
away from the fuel tank and battery.
To remove cables, reverse order
• Remove BLACK cable first from chassis 
and then from the fully charged battery.
• Remove RED cable last from both 
batteries.
WA R N I N G !
Lead-acid batteries generate 
explosive gases. Keep sparks, 
flame and smoking materials 
away from batteries. Always 
wear eye protection when 
around batteries.

Jumper cables connection
IMPORTANT INFORMATION
Your mower is equipped with a 12-volt 
negative grounded system. The other 
vehicle must also be a 12-volt negative 
grounded system. Do not use your mower 
battery to start other vehicles.
