INTRODUCTION
Introduction
Congratulations
Thank you for purchasing a Yazoo/Kees ride-on mower. This machine is built for the greatest efficiency
and rapid mowing of large areas. Convenient controls and a hydrostatic transmission regulated by
steering levers also contribute to the machine’s performance.
This manual is a valuable document. Following the instructions (use, service, maintenance, etc.) can
considerably increase the life-span of your machine and even increase its resale value.
If you sell your machine, be sure to give the operator’s manual to the new owner.
The final chapter of this operator’s manual comprises a Service Journal. Ensure that service and
repair work is documented. A well kept service journal reduces service costs of the season-based
maintenance and affects the machine’s resale value. Take the operator’s manual along when the
machine is left at the service center for service.
General
In this operator’s manual, left and right, backward and forward are used in relation to the machine’s
normal driving direction.
Driving and Transport on Public Roads
Check applicable road traffic regulations before driving and transporting on public roads. If the machine
is transported, you should always use approved fastening equipment and ensure that the machine is
well anchored.
Operating
This machine is constructed only for mowing grass on lawns and other free and even ground without
obstacles such as stones, tree stubs, etc. The machine can also be used for other tasks when equipped
with special accessories provided by the manufacturer, for which the operating instructions are pro-
vided in conjunction with delivery. All other types of use are incorrect. The manufacturer’s directions
concerning operation, maintenance, and repairs must be carefully followed.
The machine must only be operated, maintained, and repaired by persons that are familiar with the
machine’s special characteristics and who are well versed in the safety instructions.
Accident prevention regulations, other general safety regulations, occupational safety rules, and traffic
regulations must be followed without fail.
Unauthorized modifications to the design of the machine may absolve the manufacturer from liability
for any resulting personal injury or property damage.

SAFETY INSTRUCTIONS
•Be careful when rounding fixed objects, so that
the blades do not hit them. Never drive over
foreign objects.
•Only use the machine in daylight or in other
well-lit conditions. Keep the machine a safe
distance from holes or other irregularities in
the ground. Pay attention to other possible
risks.
•Never use the machine if you are tired, if you

blades, pull back the parking brake, stop the
engine, and remove the ignition key before
leaving the machine.
•Never allow children or other persons not
trained in the use of the machine to use or
service it. Local laws may regulate the age of

haust contains carbon monoxide,
which is colorless, poisonous gas.
Do not use the machine in en-
closed spaces.
WARNING!
WARNING!
When using the machine, approved personal protective equipment shall be used.

close at hand when using the machine.
•Never use the machine when barefoot. Always
wear protective shoes or boots, preferably with

6003-004
Mow up and down, not side-to-side.
Driving on Slopes
SAFETY INSTRUCTIONS
Driving on slopes is one of the operations where
the risk is greatest that the driver will lose control
or the machine will tip over, which can result in
serious injury or death. All slopes require extra
caution. If you cannot reverse up a slope or if feel
unsure, do not mow the slope.
Do as follows:
•Remove obstacles such as stones, tree
branches, etc.
•Mow up and down, not side-to-side.
•Never drive the rider on terrain that slopes
more than 10°.
•Avoid starting or stopping on a slope, If the
tires begin to slip, shut down the blades and
drive slowly down the slope.
•Always drive evenly and slowly on slopes.
•Make no sudden changes in speed or direc-
tion.
•Avoid unnecessary turns on slopes, and if it
proves necessary, turn slowly and gradually
downward, if possible.
•Watch out for and avoid driving over furrows,
holes, and bumps. On uneven terrain, the
machine can tip more easily. Long grass can
hide obstacles.
•Drive slowly. Use small movements of the
steering controls.
•Be extra cautious with any additional equip-
ment, which can alter the machine’s stability.
•Do not mow near verges, ditches, or banks.
The machine can suddenly spin around if a
wheel goes over the edge of a drop or ditch,
or if an edge gives way.
•Do not mow wet grass. It is slippery, and the
tires can lose their grip, so that the machine
slides.
•Try not to stabilize the machine by putting a
foot on the ground.
•When cleaning the chassis, the machine may
never be driven near verges or ditches.
8011-519
Be extra cautious when driving on slopes.
•Avoid starting or stopping on a slope. If tires
lose traction, disengage the blades and pro-
ceed slowly straight down the slope.
•If machine stops while going uphill, disengage
blades and back down slowly.
•Do not turn on slopes unless necessary, and
then, turn slowly and gradually downhill, if pos-
sible.

SAFETY INSTRUCTIONS
Children:
•Serious accidents may occur if you fail to be
on guard for children in the vicinity of the ma-
chine. Children are often attracted to the ma-
chine and mowing work. Never assume that
children will stay put where you last saw them.
•Keep children away from the mowing area and
under close supervision by another adult.
•Keep an eye out and shut off the machine if
children enter the work area.
•Before and during a reversing maneuver, look
backward and downward for small children.
•Never allow a child to ride with you. They can
fall off and injure themselves seriously or pre-
vent risk-free maneuvering of the machine.
•Never allow children to operate the machine.
•Be particularly cautious near corners, bushes,
trees, or other objects that block your view.
WARNING!
The engine must not be started when the driver’s floor plate or any protective
plate for the mower deck’s drive belt is removed.
•Stop the engine. Prevent the engine from start-
ing by removing the ignition key before mak-
ing any adjustments or performing mainte-
nance.
•Never fill the fuel tank indoors.
•Fuel and fuel fumes are poisonous and ex-
tremely flammable. Be especially cautious
when handling fuel, as carelessness can re-
sult in personal injury or fire.
•Only store fuel in containers approved for the
purpose.
•Never remove the fuel tank cap and never fill
the fuel tank while the engine is running.
