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.

8011-518

Keep children away from the work area.

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.

Maintenance:

8011-517

Never allow children to operate the machine.

8011-516

Never fill the fuel tank indoors.

•Allow the engine to cool before refueling. Do

not smoke. Do not fill fuel in the vicinity of

sparks or open flames.

•If leaks arise in the fuel system, the engine

must not be started until the problem has been

resolved.

•Store the machine and fuel in such a way that

there is no risk of leaking fuel or fuel vapor

leading to damages.

•Check the fuel level before each use and leave

space for the fuel to expand, because the heat

from the engine and the sun may otherwise

cause the fuel to expand and overflow.

•Avoid overfilling. If you spill fuel on the machine,

wipe up the spill and wait until it has evapo-

rated before starting the engine. If you have

spilled fuel on your clothing, change your

clothing.

•Allow the machine to cool before taking any

actions in the engine compartment.

•Be very careful when handling battery acid.

Acid on skin can cause serious corrosive

burns. If you spill battery acid on your skin,

rinse immediately with water.

•Acid in the eyes can cause blindness, con-

tact a doctor immediately.

•Be careful when servicing the battery. Explo-

sive gases form in the battery. Never perform

maintenance on the battery when smoking or

near open flames or sparks. The battery can

explode and cause serious injury/damage.

•Ensure that nuts and bolts, especially the fas-

tening bolts for the blade attachments, are

properly tightened and that the equipment is

in good condition.

•Do not modify safety equipment. Check regu-

larly to be sure it works properly. The machine

must not be driven with defective or un-

mounted protective plates, protective cowl-

ings, safety switches, or other protective de-

vices.

•Do not change the settings of governors and

avoid running the engine with overly high en-

gine speed. If you run the engine too fast, you

risk damaging the machine components.

SAFETY INSTRUCTIONS

The engine, the exhaust system,

and the hydraulic system’s compo-

nents become very warm during

operation.

Risk for burns if touched.

WARNING!

The battery contains lead and lead

compounds, chemicals that are

considered to cause cancer, birth

defects, and other reproductive

system damage.

battery.

WARNING!

8011-563

Do not smoke when performing maintenance on the

battery. The battery can explode and cause serious

injury/damage.

•Never use the machine indoors or in spaces

lacking proper ventilation. The exhaust fumes

contain carbon monoxide, and odorless, poi-

sonous, and lethal gas.

•Stop and inspect the equipment if you run over

or into anything. If necessary, make repairs

before starting.

•Never make adjustments with the engine run-

ning.

•The machine is tested and approved only with

the equipment originally provided or recom-

mended by the manufacturer.

•The blades are sharp and can cause cuts and

gashes. Wrap the blades or us protective

gloves when handling them.

•Check the parking brake’s functionality regu-

larly. Adjust and service as necessary.

•The mulch deck shall only be used when higher

quality mowing is desired in familiar areas.

•Reduce the risk of fire by removing grass,

leaves, and other debris that may have accu-

mulated on the machine. Allow the machine

to cool before putting it in storage.

•If a hydraulic leak is suspected, use a piece of

cardboard or wood, NOT your hands to check

for leaks.

•Escaping hydraulic oil under pressure can

have sufficient force to penetrate the skin,

causing serious injury. If injured by escaping

fluid, see a doctor at once. Serious infection

or reaction can develop if proper medical treat-

ment is not administered immdediately.

SAFETY INSTRUCTIONS

Transport:

•The machine is heavy and can cause serious

crushing injuries. Be extra cautious when it is

loaded on or unloaded from a vehicle or trailer.

•Use an approved trailer to transport the ma-

chine. Activate the parking brake, turn off the

CONTROLS

Be familiar with all controls their function and how

to operate them before starting the machine.

Motion Control Levers

Motion control levers on each side of the console

control the direction of movement. The left lever

controls the flow of oil from the left hydro pump to

the left wheel motor. The right lever controls the

flow of oil from the right hydro pump to the right

wheel motor.

NOTE: To begin motion the operator must be in

the seat and the parking brake disengaged before

the motion control levers can be moved from the

neutral slots or the engine will kill.

By moving the levers an equal amount forward or

back the machine will move in a straight line in

that direction. FIG - 7.

Movement of either lever forward will cause the

right or left wheel to rotate in a forward direction.

To stop movement pull both levers into the neutral

position.

To turn right while moving in a forward direction

pull the right lever back towards the neutral posi-

tion, this will slow the rotation of the right wheel

and cause the machine to turn in that direction.

To turn left while moving in a forward direction pull

the left lever back towards the neutral position,

this will slow the rotation of the left wheel and

cause the machine to turn in that direction.

To zero turn pull one lever back beyond neutral

while holding the other slightly ahead of neutral.

NOTE: The direction of the zero turn will be deter-

mined by which lever is pulled back beyond neu-

tral. Thus left lever back, left zero turn and oppo-

site for right zero turn. Use extra care when us-

ing this maneuver the machine can spin very

rapidly if one lever is positioned to far ahead

of the other.

Blade Switch

Blade engagement switch located on the console

is engaged by pulling up on the switch and pushed

down to disengage. FIG - 8.

Choke Control

Choke control is located on the console. To choke

engine pull knob push to release. FIG - 8.

Hour Meter

The hour meter displays the total operating time

and reminds of service intervals.

Meter will indicate “CHG OIL” for engine oil and

“SVC” for general service at preset intervals.

The hour meter will reset itself at predetermined

times.

Engine “CHG” will come on after the first ten (10)

hours of operation, and will stay on for one (1)

hour of operation before it will reset itself. It will

come on every 99 hours thereafter, and stay on

for five (5) hours of operation before resetting.

Mower “SVC” message will come on every 50

hours to remind to lubricate the unit, check blades

and fasteners, etc. This message will stay on for

two (2) hours of operation before resetting.

Fuel shut off valve is located at the right rear of the

seat. The valve has three positions a right tank, left

tank and center is the off position. FIG - 9.

The pump release valves are located at the right

front corner of the pumps. Used to release the

system so the machine may be moved by hand

when not running. Tilt seat forward to gain access

to the pumps. Use a 5/8” wrench to open valve.

NOTE: Only rotate valve 1/4 turn to release sys-

tem.

Tracking

The tracking knob is located in front of the left con-

trol lever. Rotating this knob allows fine tuning ad-

justments so that the machine tracks straight with

the drive levers in the full forward position.

Rotate the knob clockwise (as viewed from the

operating position) to increase the speed or coun-

terclockwise to decrease the speed on the left

control lever. Example: If control levers are full for-

ward and the unit turns to the right, turn the track-

ing knob counterclockwise to decrease the speed

on the left control lever.

Maintenance

Annual inspection and maintenance from an au-

thorized Yazoo/Kees dealer is recommended to

keep your machine in the best condition mechani-

cally and ensures safe operation.

Engine oil

Engine oil should be checked daily before starting

the machine. See the engine manufacturers

manual for specifications on type of oil, filling in-

structions and service intervals. FIG - 10

Mower blades

Inspect blades and sharpen or replace as needed.

Check blades daily or as needed. Bent, cracked

or blades with large notches in them should be

replaced. Sharpen to an angle of 22 to 28 degrees.

Always check the balance of the blades after

sharpening to prevent excessive vibration.

MAINTENANCE

Safety interlock system

Check daily and never operate the machine if the

system is not functioning properly. The starter

should crank only when the operator is in the seat,

the parking brake is applied, blade switch off and

the motion control levers in the neutral slots. If the

machine starts with any of these controls in an

operating position, turn the machine off and re-

pair the system immediately.

Cutter Housings

Grease housings once weekly or every 40 to 50

hours of use. Use a good synthetic grease. Pump

grease in until a small amount purges from the

popet on the underside of the deck. Check the

torque of the pulley bolt (45 ft/lbs) should be main-

tained.

WARNING!

No settings or adjustments are to be

made unless: Engine is stopped, key has

been removed, park brake is on and bat-

tery cable removed from battery.

Hardware

Check daily. Inspect the entire machine for loose

or missing hardware.

Air filter

See engine manufacturers specifications for

cleaning and replacement intervals.

Hydraulic system

Check oil level in tank daily. Oil level should be 3/

4” to 1” below the top of the tank. Check all fit-

tings, hoses and lines for damage or leaks. Re-

place or repair any questionable lines or fittings.

Change the oil and filter after the first 250 hours of

operation then annually after that. Drain tank and

remove filter, be sure to clean around the tank and

filter head before removal. Replace filter and drain

plug and refill hydraulic tank. Only use MOBIL 1

synthetic oil. FIG - 11.

Raise and block up the rear of the machine so the

drive wheels can rotate freely. Start the engine at

the lowest RPM possible, move the motion con-

trol levers forward and run machine for several

minutes. Stop engine and recheck the oil level.

If the wheels do not respond an air lock has oc-

curred within the system. The system must be

bled off of air or let the machine set overnight to

allow the air time to dissipate out of the oil. DO

NOT run the machine with an air lock serious dam-

age can occur to the pumps and wheel motors.

Deck belt

Check every 75 to 100 hours of operation. Check

for severe cracking and large nicks. NOTE: The

belt will show some small cracks in normal op-

eration.

To replace belt lower the deck to its lowest posi-

tion. Remove the foot plate and belt shields. Use

a ratchet with a 9/16” socket on the spring idler

bolt to relieve the tension on the belt. Slide the belt

off of pulley and fully remove the belt. Reverse the

proceedure for installation. See the decal on the

top of deck for belt routing information. FIG - 12.

After installation is complete check the belt for

twists.

WARNING!

If a leak is suspected, use a piece of

cardboard or wood, NOT your hands. to

check for leaks.

Escaping hydraulic oil under pressure

can have sufficient force to penetrate

the skin, causing serious injury.

If injured by escaping fluid, see a doctor

at once. Serious infection or reaction

can develop if proper medical treatment

is not administered immdediately.

MAINTENANCE

Pump belt

Check belt every 100 hours for excessive wear.

To replace belt. Relieve tension on the deck belt

and remove deck belt from clutch. See deck belt

instructions on previous page. Loosen bolt on the

clutch tie down and rotate out of the way. Using a

1/2” drive ratchet inserted into the square hole in

the pump idler arm relieve the tension on the pump

belt and remove belt. To reinstall belt. Swing pump

idler pulley out toward engine to route belt around

it. Then route belt around right side pulley first as

you are looking up from the underside of machine.

Reinstall idler spring and use the ratchet to rotate

idler so the belt may be installed all the way around

the last pulley.

Lubrication

See service decal under foot plate for service

points and maintenance intervals. Clean grease

zerks thoroughly before greasing. See engine

manual for engine service. FIG - 13.

Tire pressure

Check every 25 hours. All four tires require 15 psi.

FIG - 13

Winter storage

To prepare the machine for storage. Clean the

machine, especialy under the deck. Touch-up the

paint or spray the underside of deck with a light

coat of oil.

Inspect the machine for damage and loose hard-

ware.

Change the oil.

Drain the fuel system or add stabilizer to fuel. Make

sure to run the machine after to circulate stabi-

lizer throughout system.

Remove the plugs and add 1 tablespoon of oil in

each cylinder. Install plugs and crank the engine

two or three revolutions.

Grease all zerks.

Remove battery and store inside and protect it

from freezing temperatures.

Caster Wheels

Check every 200 hours. Lift front of unit off of

ground so caster wheels can rotate freely. Tighten

caster bolt then back off 1/2 turn. Check that wheel

rotates freely. If wheel does not rotate freely back

the caster bolt off in 1/4 turn increments until wheel

rotates freely.

NOTE: DO NOT add any type of tire liner or foam

fill material to the tires. Excessive loads created

by foam filled tires will cause premature failures.

Only use O.E.M. specified tires. Foam filling tires

or solid tires will void the warrany.

Fuel filter

Replace every 500 hours or annually. In extremely

dirty conditions replacement may need to be at

shorter intervals.
