Safety  
DANGER  
DANGER  
In certain conditions gasoline is extremely  
flammable and vapors are explosive.  
In certain conditions during fueling, static  
electricity can be released causing a spark  
which can ignite gasoline vapors. A fire or  
explosion from gasoline can burn you and  
others and cause property damage.  
A fire or explosion from gasoline can burn  
you, others, and cause property damage.  
• Fill the fuel tank outdoors in an open  
area, when the engine is cold. Wipe up  
any gasoline that spills.  
• Always place gasoline containers on the  
ground away from your vehicle before  
filling.  
• Never refill the fuel tank or drain the  
machine indoors or inside an enclosed  
trailer.  
• Do Not fill gasoline containers inside a  
vehicle or on a truck or trailer bed because  
interior carpets or plastic truck bed liners  
may insulate the container and slow the  
loss of any static charge.  
• Do Not fill the fuel tank completely  
full. Add gasoline to the fuel tank until  
the level is 1/4 to 1/2 inch (6–13 mm)  
below the bottom of the filler neck. This  
empty space in the tank allows gasoline  
to expand.  
• When practical, remove gas-powered  
equipment from the truck or trailer and  
refuel the equipment with its wheels on  
the ground.  
• Never smoke when handling gasoline,  
and stay away from an open flame or  
where gasoline fumes may be ignited by  
spark.  
• If this is not possible, then refuel such  
equipment on a truck or trailer from a  
portable container, rather than from a  
gasoline dispenser nozzle.  
• Store gasoline in an approved container  
and keep it out of the reach of children.  
• If a gasoline dispenser nozzle must be  
used, keep the nozzle in contact with the  
rim of the fuel tank or container opening  
at all times until fueling is complete.  
• Add fuel before starting the engine.  
Never remove the cap of the fuel tank or  
add fuel when engine is running or when  
the engine is hot.  
WARNING  
• If fuel is spilled, Do Not attempt to start  
the engine. Move away from the area of  
the spill and avoid creating any source of  
ignition until fuel vapors have dissipated.  
Gasoline is harmful or fatal if swallowed.  
Long-term exposure to vapors has caused  
cancer in laboratory animals. Failure to use  
caution may cause serious injury or illness.  
• Do Not operate without entire exhaust  
system in place and in proper working  
condition.  
• Avoid prolonged breathing of vapors.  
• Keep face away from nozzle and gas  
tank/container opening.  
• Keep away from eyes and skin.  
• Never siphon by mouth.  
• Check that the operator’s presence controls,  
safety switches, and shields are attached and  
functioning properly. Do Not operate unless they  
are functioning properly.

change the operating angle, as rough terrain could  
overturn the machine.  
• Keep hands and feet away from moving parts.  
If possible, do not make adjustments with the  
engine running.  
• Avoid sudden starts when mowing uphill because  
the mower may tip backwards.  
• Be aware that operating on wet grass, across steep  
slopes or downhill may cause the mower to lose  
traction. Loss of traction to the drive wheels may  
result in sliding and a loss of braking and steering.  
• Charge batteries in an open well ventilated area,  
away from spark and flames. Unplug charger  
before connecting or disconnecting from battery.  
Wear protective clothing and use insulated tools.  
• Always avoid sudden starting or stopping on a  
slope. If tires lose traction, disengage the blades  
and proceed slowly off the slope.

Operation  
Note: Determine the left and right sides of the  
Squeezing the left hand and/or right hand lever  
causes the left hand and/or right hand drive wheel  
respectively to slow down, stop, or reverse, depending  
on how far each drive lever is “squeezed”. Squeezing

Controls  
Operator Presence Control (OPC)  
Levers  
Located on the upper handle assembly directly above  
the handle grips.  
Neutral Lock Latches  
Located on the upper handle assembly on the ends  
of the handle grips.  
When these levers are depressed, the OPC system  
senses that the operator is in the normal operator’s  
position. When the levers are released, the OPC  
system senses that the operator has moved from the  
normal operating position and will kill the engine if  
either the speed control lever is not in the neutral  
position or the PTO is engaged.  
These latches allow the operator to lock the drive  
levers in a “neutral” position where the drive wheels  
are not engaged in either a forward or reverse  
direction.  
Choke Control  
Located on the control console front right hand side.  
Choke is used to aid in starting a cold engine. The  
choke control is pulled out to be in the “ON” position  
and pushed in to be in the “OFF” position. Do Not  
run a warm engine with choke in the “ON” position.  
Throttle Control  
Located on the control console’s right side.  
The throttle is used to control engine speed. Moving  
the throttle control forward will increase engine  
speed and moving it to the rear will decrease engine  
speed. Moving the throttle forward into the detent  
is full position.

Ignition Switch  
Located on the right-hand side of the rear of the fuel  
tank support.  
Located on the left side of the control console.  
The ignition switch is used to start and stop the  
engine. The ignition switch has three positions,  
“Off ”, “On” and “Start”. Insert key into switch  
and rotate clockwise to the “On” position. Rotate  
clockwise to the next position to engage the starter  
(key must be held against spring pressure in this  
position). Operator must have speed control lever in  
neutral, OPC levers depressed and PTO disengaged  
to start engine. When engine starts, release key.  
The knob can be adjusted so that machine will  
“track” straight ahead with the drive levers released.

The hour meter is connected to a pressure switch  
installed in the engine block and it records the  
number of hours that the engine has run. If ignition  
switch is left on without engine running, hour meter  
will not run.  
Pre-Start  
Fill fuel tanks. For best results use only clean, fresh  
regular grade unleaded gasoline with an octane rating  
of 87 or higher. Regular grade leaded gasoline may  
also be used; however, combustion chamber and  
cylinder head will require more frequent service. See  
Engine Owner’s Manual.  
Note: This switch is not a low oil sensor and will not  
alert the operator if the engine oil is low.  
Do Not add oil to gasoline.  
Fuel Shut-Off Valve  
Do Not overfill fuel tank. Never fill the fuel tank so  
that the fuel level rises above a level that is 1/2 inch  
below the bottom of the filler neck to allow for fuel  
expansion and prevent fuel spillage.  
Located in the fuel line midway between the tank  
and engine.  
The fuel shut-off valve is used to shut off the  
flow of fuel when parking inside a building, during  
transportation to and from the job sites, and when  
the machine will not be used for a few days.  
Make sure you understand the controls, their  
locations, their functions, and their safety  
requirements.

that no dirt or contamination enter hydraulic  
system.  
Air must be purged from the hydraulic system  
when any hydraulic components, including oil  
filter, are removed or any of the hydraulic lines are  
disconnected.  
The critical area for purging air from the hydraulic  
system is between the oil reservoir and each  
charge pump located on the top of each variable  
displacement pump (Figure 13). Air in other parts of  
the hydraulic system will be purged through normal  
operation once the charge pump is “primed”.  
3. Unscrew filter to remove and allow oil to drain  
from reservoir.  
Important: Before reinstalling new filter, fill  
it with Exmark Premium Hydro oil and apply  
a thin coat of oil on the surface of the rubber  
seal.
