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.

Safety  
• Check that the operator’s presence controls,  
safety switches, and shields are attached and  
functioning properly. Do Not operate unless they  
are functioning properly.  
WARNING  
Operating a Navigator tractor without an  
approved Exmark front mount attachment  
increases the possibility of operator  
entanglement in drive wheels or forward tip  
over. Entanglement or tip-over could cause  
serious injury or death.  
Operation  
WARNING  
When operating a Navigator tractor  
without an approved Exmark front mount  
attachment, observe the following:

Operation  
Drive Wheel Release Valves  
Pre-Start  
Located on the top left front corner of hydrostatic  
pumps.  
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.  
Drive wheel release valves are used to release the  
hydrostatic drive system to allow the machine to be  
pushed without the engine running. Tilt seat up to  
gain access to pumps.  
Do Not add oil to gasoline.  
With a 7/16 wrench, turn both valves one turn  
counterclockwise to release drive system. Turn  
clockwise to reset system. Do Not overtighten. Do  
Not tow machine.  
Do Not overfill fuel tank. Never fill the fuel tank so  
that the fuel level rises above a level that is 1/2 inch  
(13 mm) below the bottom of the filler neck to allow  
for fuel expansion and prevent fuel spillage.  
Tracking Adjustment Knob  
Make sure you understand the controls, their  
locations, their functions, and their safety  
requirements.  
Located under the seat on the left pump control link.  
Rotating this knob allows fine tuning adjustments so  
that the machine tracks straight with the drive levers  
in the full forward position.  
Refer to the Maintenance section and perform all the  
necessary inspection and maintenance steps.  
Run unit at 3/4 speed for at least 5 minutes to  
bring hydraulic oil up to operating temperature.

Operation  
WARNING  
Loading a unit on a trailer or truck increases  
the possibility of tip-over. Tip-over could  
cause serious injury or death.  
• Use extreme caution when operating a  
unit on a ramp.  
• Use only a single, full width ramp; Do  
Not use individual ramps for each side  
of the unit.  
• If individual ramps must be used, use  
enough ramps to create an unbroken  
ramp surface wider than the unit.  
• Do Not exceed a 15° angle between ramp  
and ground or between ramp and trailer  
or truck.  
• Avoid sudden acceleration while driving  
unit on a ramp.  
Loading a Unit  
Use extreme caution when loading units on trailers  
or trucks. One full width ramp is required. If it is  
not possible to use one full width ramp, use enough  
individual ramps to simulate a full width continuous  
ramp.  
Ramp should be long enough so that the angles  
between the ramp and the ground and the ramp and  
the trailer or truck do not exceed 15°. A steeper angle  
may cause mower deck components to get caught as  
the unit moves from ramp to trailer or truck. Steeper  
angles may also cause the unit to tip. If loading on or  
near a slope, position the trailer or truck so it is on  
the down side of the slope and the ramp extends up  
the slope. This will minimize the ramp angle. The  
trailer or truck should be as level as possible.  
Important: Do Not attempt to turn the unit  
while on the ramp, you may lose control and  
drive off the side.  
Avoid sudden acceleration when driving on a ramp.

machine, especially around the fuel tank, around  
engine and exhaust area.  
CAUTION  
Excessive debris around the engine cooling  
air intake and inside of the pump drive  
belt compartment and damaged or missing  
rubber baffles can cause the engine and  
hydraulic system to overheat which can  
create a fire hazard.  
Waste Disposal  
Motor Oil Disposal  
Engine oil and hydraulic oil are both pollutants to  
the environment. Dispose of used oil at a certified  
recycling center or according to your state and local  
regulations.  
Clean all debris from inside of pump drive  
belt compartment daily.  
1. Stop engine, wait for all moving parts to stop, and  
remove key. Engage parking brake.  
Battery Disposal  
2. Clean all debris from rotating engine air intake  
screen and from around engine shrouding and  
exhaust system area.  
DANGER  
Battery electrolyte contains sulfuric acid,  
which is poisonous and can cause severe  
burns. Swallowing electrolyte can be fatal or  
if it touches skin can cause severe burns.  
3. Clean all debris from around engine, drive belts,  
and exhaust system area.  
Remove Engine Shrouds and  
Clean Cooling Fins  
• Wear safety glasses to shield eyes, and

Federal law states that batteries should not be placed  
in the garbage. Management and disposal practices  
must be within relevant federal, state, or local laws.  
2. Remove cooling shroud clean-out covers from  
engine and clean cooling fins. Also clean dust,  
dirt, and oil from external surfaces of engine,  
which can cause improper cooling.  
If a battery is being replaced or if the unit containing  
the battery is no longer operating and is being  
scrapped, take the battery to a local certified recycling  
center. If no local recycling is available return the  
battery to any certified battery reseller.  
3. Make sure cooling shroud clean-out covers are  
reinstalled. Operating the engine without cooling  
shroud clean-out covers will cause engine damage  
due to overheating.
