THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF NOT FOLLOWED, COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL BEFORE ATTEMPTING TO OPERATE YOUR UNIT. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT

IN PERSONAL INJURY. WHEN YOU SEE THIS SYMBOL-- A_. HEED ITS WARNING.

Your lawn mower was built to be operated according to the rules for safe operation

in this manual, As with any type of power equipment, carelessness or error on the

DANGER part of the operator can result in injury.This lawn mower is capable of amputating

hands and feet or throwing objects. Failure to observe the following safety instructions could result in serious injury or death.

1. GENERAL OPERATION

1. Read, understand and follow all instructions in the manual and on the machine before starting. Keep

this manual in a safe place for future and regular reference.

Only allow responsible individuals familiar with the instructionsto operate the machine. Know the

controls and how to stop the machine quickly. Do not put hands or feet under the cutting deck or

near rotatingparts.

Clear the area of objects such as rocks, toys,

wire, etc. which could be picked up and thrown by the blades. A small object may have been

overlooked and could be accidentally thrown by the mower in any direction and cause injury to you or a bystander. To help avoid a thrown

objects injury, keep children, animals, bystanders and helpers at least 75 feet from the mower while

it is in operation. Always wear safety glasses with side shields or safety goggles during operation or

while performing an adjustment or repair, to

protect eyes from foreign objects. Stop the blades

when crossing gravel drives, walks or roads.

5. Be sure the area is clear of other people before mowing. Stop machine if anyone enters the area.

6. Never carry passengers.

7. Disengage the blades before shifting into reverse and backing up. Always look down and behind

before and while backing.

8. Be aware of the mower and attachment discharge direction and do not point it at anyone. Do not

operate the mower without either the entire grass

catcher or the chute guard in place.

9. Slow down before turning. Operate the machine smoothly. Avoid erratic operation and excessive speed.

I0. Never leave a running machine unattended.

Always turn off the blades, place the transmission in neutral, set the parking brake, stop the engine

and remove key before dismounting.

11.

12.

Turn off blades when not mowing. Stop the engine and wait until the blades come to

a complete stop before (a) removing the grass catcher or unclogging chute, or (b) making any

repairs, adjusting or removing any grass or debris.

13. Mow only in daylight or good artificial light.

14. Do not operate the machine while under the influence of alcohol or drugs.

15. Watch for traffic when operating near or crossing roadways.

16. Use extra care when loading or unloading the machine into a trailer or truck. This unit should not

be driven up or down a ramp onto a trailer or truck under power, because the unit could tip over

causing serious personal injury. The unit must be

pushed manually on a ramp to load or unload properly.

17. Never make a cutting height adjustment while the

engine is running if the operator must dismount to do so.

18.

Wear sturdy, rough-soled work shoes and close- fitting slacks and shirts. Do not wear loose fitting

clothes or jewelry. They can be caught in moving parts. Never operate a unit in bare feet, sandals

or sneakers.

!9. Check overhead clearance carefully before driving

under power lines, wires, bridges or low hanging

tree branches, before entering or leaving

buildings, or in any other situation where the

operator may be struck or putled from the unit, which could result in serious injury.

20. Disengage all attachment clutches, set the parking brake in the on position, and put the tap bars to the neutral or out position before

attempting to start the engine.

21. Your mower is designed to cut normal residential grass of a height no more than 10". Do not

attempt to mow through unusually tall, dry grass (e.g. pasture) or piles of dry leaves. Debris may

build up on the mower deck or contact the engine

exhaust presenting a potential fire hazard.

22. Use only accessories approved for this machine by Cub Cadet. Read, understand and follow all

instructions provided with the approved accessory.

_11. SLOPE OPERATIQN

Slopes are a major factor related to loss of control and

tip-over accidents, which can result in severe injury or

death. All slopes require extra caution. If you cannot back up the slope or if you feel uneasy on it, do not

mow it. For your safety, use the slope gauge included as part

of this manual to measure slopes before operating this unit on a sloped or hilly area. If the slope is greater than I5 ° as shown on the slope gauge, do not operate

this unit on that area or serious injury could result.

DO:

Mow across slopes, not up and down. Keep all movement on the slopes slow and gradual.

Do not make sudden changes in speed or direction. Rapid acceleration or deceleration could cause the

front of the machine to lift and rapidly flip over back- wards, which could cause serious injury.

Avoid starting or stopping on a slope. If the tires are unable to maintain traction, disengage the blades and

proceed slowly and carefully straight down the slope. Do not mow the slope until able to maintain traction.

Use slow speed. Choose a low enough speed so that

you will not have to stop while on the slope.

Remove obstacles such as rocks, limbs, etc.

Watch for holes, ruts or bumps. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

Follow the manufacturer's recommendations for coun-

terweights with attachments to improve stability. Use extra care with grass catchers or other attach-

ments. These can change the stability of the machine.

DO NOT:

Do not turn on slopes unless necessary; then turn

slowly and use extra care while turning.

Do not mow near drop-offs, ditches or embankments.

The mower could suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in.

Do not mow on wet grass. Reduced traction could cause sliding.

Do not try to stabilize the machine by putting your foot on the ground.

Do not use the grass catcher on steep slopes.

III. CHILDREN

Tragic accidents can occur if the operator is not alert

to the presence of children. Children are often attracted to the machine and the mowing activity.

Never assume that children will remain where you last saw them.

1. Keep children out of the mowing area and in watchful care of an adult other than the operator.

2. Be alert and turn the machine off if children enter the area.

Before and when backing up, took behind and down for small children.

Never carry children, even with the blades off.

They may fall off and be seriously injured or may

interfere with safe machine operation.

5. Never allow children under 14 years old to operate the machine. Children 14 years and over

should only operate the machine under close parental supervision and proper instruction.

6. Use extra care when approaching blind corners, shrubs, trees or other objects that may obscure

your vision of a child or other hazard.

7. Remove the key when the machine is left unattended to prevent unauthorized operation.

IV. SERVICE

Use extreme care in handlinggasoline and other

fuels. They are extremely flammable and the vapors are explosive.

a. Use only an approved container. b. Never remove fuel cap or add fuel with the en-

gine running. Allow the engine to cool at least

two minutes before refueling.

c. Replace the fuel cap securely and wipe off any

spilled fuel before starting the engine as it may cause a fire or explosion.

d. Extinguish all cigarettes, cigars, pipes and oth-

er sources of ignition.

e. Never refuel the machine indoors because fuel

vapors will accumulate in the area.

f. Never store the fuel container or machine

inside where there is an open flame or spark, such as a gas hot water heater, space heater

or furnace.

Never run a machine inside a closed area.

To reduce fire hazard, keep the machine free of grass, leaves or other debris build-up. Clean up

oil or fuel spillage. Allow the machine to cool at least 5 minutes before storing.

4. Before cleaning, repairing or inspecting, make certain the blade and all moving parts have stopped. Disconnect the spark plug wire, and

keep the wire away from the spark ptug to prevent

accidental starting.

5. Check the blade and engine mounting bolts at fre-

quent intervals for proper tightness. Also visually

inspect blades for damage (e.g., excessive wear,

bent, cracked). Replace with blades which meet original equipment specifications.

6. Keep all nuts, bolts and screws tight to be sure

the equipment is in safe working condition.

7. Never tamper with safety devices. Check their

proper operation regularly. Use all guards as instructed in this manual.

8. After striking a foreign object, stop the engine, remove the wire from the spark plug and

thoroughly inspect the mower for any damage.

Repair the damage before restarting and

operating the mower.

9. Grass catcher components are subject to wear, damage and deterioration, which could expose moving parts or altow objects to be thrown. For your safety protection, frequently check the components and replace with manufacturer's recommended parts when necessary.

10. Mower blades are sharp and can cut. Wrap the blades or wear gloves, and use extra caution

when servicing blades.

11. Check the park brake operation frequently. Adjust and service as required.

12+Muffler, engine and belt guards become hot

during operation and can cause a burn. Allow to

cool down before touching.

13. Do not change the engine governor settings or

overspeed the engine. Excessive engine speeds are dangerous.

14. Observe proper disposal laws and regulations. Improper disposal of fluids and materials can

harm the environment and the ecology. a. Prior to disposal, contact your local

Environmental Protection Agency to determine the proper method for disposing of

the waste. Recycling centers are established to properly dispose of materials in an environmentally safe fashion.

b. Use proper containers when draining fluids.

Do not use food or beverage containers that may mislead someone into drinking from

them. Properly dispose of the containers im-

mediately following the draining of fluids.

DO NOT pour oil or other fluids into the ground, down a drain or into a stream, pond,

lake, or other body of water. Observe Environ- menta] Protection Agency regulations when

disposing of oil, fuel, coolant, brake fluid, fil- ters, batteries, tires and other harmful waste.

15. With the exception of utilizing the deck wash feature, we do not recommend the use of a

pressure washer or garden hose to clean your tractor. Water may cause damage to electrical

components; pulleys; bearings; or the engine. The use of water will result in shortened life and

reduce serviceability.

_lb WARNING - YOUR RESPONSIBILITY: Restrict the use of this power machine to persons who

read, understand and follow the warnings and instructions in this manual and on the machine.

• Before starting the engine or beginning operation,

be familiar with the controls. The operator should be in the operator's seat. The PTO switch must

be in the disengaged position, the parking brake engaged, and the RH and LH drive control levers

moved fully outward in the neutral position.

• Keep all shields in place. Keep away from moving parts.

• NO RIDERS! Keep all people and pets a safe

distance away.Look behind and down to both sides of the tractor before and while backing up.

• DO NOT direct the mower discharge at people.

• Avoid slopes where possible. Never operate on

slopes greater than 15°. Slopes with a greater incline present dangerous operating conditions.

Tractors can be rolled over.

• Before leaving the operator's seat: Shut off the

PTO, move the RH and LH drive control levers fully outward in the neutral position, engage the

parking brake, shut off the engine and remove

the ignition key. Wait for all movement to stop

before servicing or cleaning.

• Operate the drive control levers smoothly and avoid any sudden movements of the levers

when starting and stopping. Keep a firm grip on the control levers; do not allow the levers to return to neutral on their own.

• Be careful when operating near roadways. Stop the tractor motion and wait for vehicles to pass

before operating along the road.

• Do not operate the tractor with the mower deck removed. Removal of the deck will change the balance of the tractor, and could contribute to a

tractor rollover.

• Avoid operation on traction surfaces that are unstable; use extreme caution if the surface is

slippery.

° Slow down before turning and come to a

complete stop before any zero turn maneuver.

• Do not stop the tractor or park the tractor over

combustible materials such as dry grass, leaves, debris, etc.

• Do not fill the fuel tank when the engine is

running or while the engine is hot. Allow the engine several minutes to cool before refueling. Tighten the fuel cap securely.

BEFORE OPERATING YOUR TRACTOR

• Before you operate the tractor,study this manual carefully to familiarize yourself with the operationsof all the instruments and controls. It

has been prepared to help you operate and maintain yourtractor efficiently.

• Familiarize yourself with the operationsof all the instruments and controls.

• This engine is certified to operate only on clean, fresh, unleaded regular gasoline. For best results,

fill the fuel tank with only clean, fresh, unleaded gasoline with a pump sticker octane rating of 87 or higher.

• Unleaded gasoline is recommended because it leaves less combustion chamber deposits and

reduces harmful exhaust emissions. Leaded gasoline is not recommended and must not be used where exhaust emissions are regulated.

NOTE: Purchase gasoline in small quantities. Do not

use gasoline left over from the previous season, to minimize gum deposits in the fuel system.

• Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is an approved fuel. Other gasoline/alcohol blends are not approved.

• Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up to a maximum of 15% MTBE

by volume) are approved fuels. Other gasoline/ ether blends are not approved.

• Check the engine oil level.

• Clean the air cleaner element if necessary.

• Check the tire inflation pressures.

• Adjust the seat for operator's maximum comfort, visibility and for maintaining complete control of

the tractor.

SAFETY INTERLOCK SYSTEM This tractor is equipped with a safety interlock system

for the protection of the operator. If the interlock system should ever malfunction, do not operate the tractor. Contact your authorized Cub Cadet Dealer.

• The safety interlock system prevents the engine

from cranking or starting unless the RH and LH

drive control levers are moved fully outward in the

neutral position, the parking brake is engaged,

and the PTO is disengaged.

• To avoid sudden movement when disengaging

the parking brake, the safety interlock system will shut off the engine if the RH and/or LH drive control levers are moved to a position other than

the fully out in neutral position when the parking brake is engaged

• The safety interlock system will shut off the engine if the operator leaves the seat before engaging the parking brake.

• The safety interlock system will shut off the engine if the operator leaves the seat with the

PTO engaged, regardless of whether the parking brake is engaged.

NOTE: The PTO switch must be moved to the

"OFF" position to restart the engine.

The safety interlocksystem will shut off the PTO and the mower blades will stop if both drive con-

trol levers are moved into the reverse position. The PTO will re-engage when one or both of the

levers are moved back to the neutral or forward position.

STARTING THE ENGINE

WARNING: This unit is equipped with a safety interlock system designed for the

protection of the operator. Do not oper- ate the tractor if any part of the interlock

system is malfunctioning. Periodically

check the functions of the interlock sys-

tem for proper operation.

_1 WARNING: For personal safety, the

operator must be sitting in the tractor

seat when starting the engine.

• Move the RH and LH drive control levers fully out- ward in theneutral position. Refer to Figure10.

• Operator mustbe sittinginthe tractorseat.

• Engagethe parkingbrake. Refer to Figure 10.

• Make certain the PTO switch is in the disen- gaged (down)position. Refer to Figure10.

• PuU the choke control knob upward to the full choke position.NOTE: If the engine is warmed

up, it may not be necessary to choke the engine.

• Move the throttle controlto midway between its

SLOW and FAST positions.

Turn the ignition key clockwise to the "START"

position and release it as soon as the engine

starts; however, do not crank the engine continu- ously for more than 5 seconds at a time. If the

engine does not start withinthis time, turn the key

to "OFF" and wait at least 15 seconds to allow the engine's starter motor to cool. Try again after waiting. If after a few attempts the engine fails to

start, do not keep trying to start it with the choke dosed as this will cause flooding and make start-

ing more difficult. As the engine warms up, gradually push the

choke knob downward to open the choke. Do not

use the choke to enrich the fuel mixture, except

as necessary to start the engine. Allow the engine to run for a few minutes at mid

throttle before putting the engine under load. Observe the hour meter/indicator panel. If the

battery indicator light or oil pressure light come on, immediately stop the engine. Have the tractor inspected by your Cub Cadet dealer.

COLD WEATHER STARTING

• When starting the engine at temperatures near or below freezing, ensure the correct viscosity motor

oil is used in the engine and the battery is fully

charged. Start the engine as follows:

° Be sure the battery is in good condition. A warm

battery has much more starting capacity than a cold battery.

• Use fresh winter grade fuel. Winter grade

gasoline has higher volatility to improve starting. Do not use gasoline left over from summer.

• Follow the previous instruction for STARTING

THE ENGINE.

USING JUMPER CABLES TO START ENGINE

WARNING: Batteries contain sulfuric acid and produce explosive gasses. Make

certain the area is well ventilated, wear gloves and eye protection, and avoid

sparks or flames near the battery,

If the battery charge is not sufficient to crank the

engine, recharge the battery. If a battery charger is

unavailable and the tractor must be started, the aid of

a booster battery will be necessary. Connect the booster battery as follows: ° Connect the end of one cable to the disabled

tractor battery's positive terminal; then connect the other end of that cable to the booster

battery's positive terminal.

° Connect one end of the other cable to the booster

battery's negative terminal; then connect the other end of that cable to the frame of the dis-

abled tractor, as far from the battery as possible.

• Start the disabled tractor following the normal starting instructions previously provided; then

disconnect the jumper cables in the exact reverse

order of their connection.

Have the tractor's electrical system checked and repaired as soon as possible to eliminate the

need for jump starting.

STOPPING THE ENGINE

" Place the PTO switch in the "OFF" position. ° Move the RH and LH drive control levers fully

outwardinthe neutralposition.

° Engagethe parkingbrake.

• Move the throttle control to the SLOW position

and allow the engine toidlefor aboutone minute.

° Turn the ignition key to the "OFF" position and

removethe key from the ignition switch.

NOTE: Always remove the key from the ignition

switch to prevent accidental starting or battery discharge if the equipment is left unattended.

PRACTICE OPERATION (INITIAL USE)

Operating a zero-turn tractor is not like operating a conventional type riding tractor. Although and be- cause a zero turn tractor is more maneuverable,get- ting used to operatingthe control levers takes some practice.

We strongly recommend that you locate a reason- ably large, leveland open "practice area" where there are no obstructions, pedestrians, or animals. You should practiceoperatingthe tractorfor a minimum_of

30 minutes.

Carefully move (or have moved) the tractor to the practice area. When performing the practice session, the PTO should not be engaged. While practicing, operate the tractor at approximately 1/2-3/4 throttle and at less than full speed in both forward and reverse.

Carefully practice maneuvering the tractor using the

instructions in the following section "Driving the Trac- tor." Practice until you are confident that you can safely operate the tractor.

DRIVING THE TRACTOR

WARNING: Avoid sudden starts, exces-

sive speed and sudden stops.

WARNING: Do not leave the seat of the tractor without disengaging the PTO,

moving drive control levers fully outward in the neutral position, and engaging the

parking brake, if leaving the tractor unattended, turn the ignition key off and remove key.

Adjust the operator's seat to the most comfortable position that allows you to operate

the controls. See seat adjustment in the

ADJUSTMENTS section.

• Release the parking brake.

• Move the RH and LH drive control levers inward

in the neutral position. Refer to Figure 11.

Control Lever Moved Inward and in Neutral

Figure 11

NOTE: If the control levers are not even in the neutral

position, refer to Section 3 and adjust the levers so

that they are even.

' Move the throttle control lever forward to the full

throttle position (3500-3600 RPM).

NOTE: The tractor and engine are designed to run at full throttle. If performing a practice session, it is

preferable that the tractor is operated at less than full

throttle (approximately 2500-3000 RPM), but this only applies to practice operation.

_L WARNING: Always maintain a firm grip

on the control levers. DO NOT release the control levers to slow or stop the tractor;

move the levers to the neutral position using your hands.

• To drive the tractor, firmly grasp the respective

drive control levers with your right and left hands and proceed as follows -

Driving the Tractor Forward

,_ WARNING: Keep all movement of the

drive control levers slow and smooth. Abrubt movement of the control levers can affect the stability of the tractor and

could cause the tractor to flip over, which may result in serious injury or

death to the operator.

• Slowly and evenly move both drive control levers forward. The tractor will start to move forward.

See Figure 12.

Executing a Zero Turn

_ WARNING: When executing a zero turn,

the tractor MUST BE STOPPED. Executing a zero turn while the tractor is

moving can significantly reduce your control of the tractor and will cause

severe turf defacement to occur.

• Stop the forward or reverse motion of the tractor by moving the two drive control levers to neutral.

• To turn clockwise, move the left control lever

forward white simultaneously moving the right control lever rearward. See Figure 18.

STOPPING THE TRACTOR

° Move both drive control levers to the neutral

position to stop the motion of thetractor.

° Push the PTO switch downward to the

disengaged position.

• Use the deck lift handle to raise the deck to its highest position.

o If dismounting the tractor, move the drive control

handles fully outward in the neutral position, engage the parking brake, move the throttle

control lever to the fast position, turn the ignition switch to "OFF'" and remove the key from the

switch.

DRIVING ON SLOPES

Refer to the SLOPE GAUGE on page 8 to help determine slopes where you may not operate safely.

_ WARNING: Do not operate on inclines

with a slope in excess of 15 degrees (a

rise of approximately 2-1/2 feet every 10

feet). The tractor could overturn and cause serious injury.

° Always drive across slopes, never up and down.

Control the speed and direction of the tractor using primarily the control lever on the downhill

side of the tractor, with the uphill control lever remaining essentially in a fixed position.

• Avoid turning downhill if possible. Start at the bottom of a slope and work upward. Always slow down before turning.

• Use extra care and go slowly when turning downhill.

OPERATING THE PTO

Operate the PTO clutch as follows:

• Move the throttle control lever to approximately the mid throttle position.

• Pull the PTO switch upward to the "ENGAGED" position.

• Advance the throttle lever to the operating speed (full engine speed).

• The operator must remain in the tractor seat at all

times. If the operator should leave the seat without turning off the power take-off switch, the tractor's engine will shut off.

• The PTO clutch cannot be operated when the

tractor is driving in the reverse direction. The

PTO will disengage when both drive control

levers are moved to the reverse position, and will re-engage when one (or both) control lever(s) is

moved to the neutral or forward position.

USING THE MOWER DECK

WARNING: Make certain the area to be mowed is free of debris, sticks, stones,

wire or other objects that can be thrown by the rotating blades.

IMPORTANT: Do not engage the mower deck when

lowered in grass. Premature wear and possible failure of the "V" belt and PTO clutch will result. Fully raise the deck or move to a non grassy area before engaging the mower deck.

• Mow across slopes, not up and down. If mowing a slope, start at bottom and work upward to ensure turns are made uphill.

• On the first pass pick a point on the opposite side of the area to be mowed.

• Engage the PTO clutch using the PTO switch and move the throttle control to the fast position.

• Lower the mower deck to the desired height setting using the lift handle.

• Slowly and evenly push the RH and LH drive control levers forward to move the tractor

forward, and keep the tractor headed directly toward the alignment point.

NOTE: The speed of the tractor will affect the

quality of the mower cut. Mowing at full speed will adversely affect the cut quality. Control the

ground speed with the control levers.

• When approaching the other end of the strip, slow down or stop before turning. A U-turn is

recommended unless a pivot or zero turn is required.

• Align the mower with an edge of the mowed strip and overlap approximately 3 inches.

• Direct the tractor on each subsequent strip to align with a previously cut strip.

• To prevent rutting or grooving of the tuff, if possible, change the direction that the strips are

mowed by approximately 45 ° for the next and each subsequent mowing.

_k WARNING: Be careful when crossing

gravel paths or driveways. Disengage the PTO and raise the deck to the

highest position before crossing.

IMPORTANT: When stopping the tractor for any

reason while on a grass surface, always:

• Place the shift lever in neutral,

• Engage the parking brake,

• Shut engine off and remove the key.

Doing so will minimize the possibility of having your lawn "browned" by hot exhaust from your tractor's

running engine.

CHECKING THE SAFETY INTERLOCK CIRCUITS

Periodically check the safety interlock circuits to ensure they are workingproperly. If a safety circuitis not working as designed, contact you Cub Cadet

dealer to have the tractorinspected. DO NOT operate

the tractor if any safety circuit is not functioning properly. To check the safet_j circuits, proceed as

follows:

Sitting in the tractor seat with both drive control levers opened fully outward, disengage the

parking brake and momentarily turn the ignition switch to the start position. The engine should not

crank.

• Engage the parking brake and pull the PTO switch upward to the engaged position.

Momentarily turn the ignition switch to the start

position; the engine should not crank.

• Push the PTO switch downward to the disen- gaged position and engage the parking brake.

Start the engine and move one of the drive con- trol levers from the fully outward neutral position.

The engine should stop running. Repeat the pro- cedure with the opposite control lever.

• Move both control levers fully outward in the neu- tral position and disengage the parking brake;

then lift upward from the operator's seat. The

engine should stop.

• With both control levers fully outward in the neu- tral position and the parking brake engaged,

engage the PTO. Lift upward from the operator's

seat; the engine should stop.

• Start the tractor, disengage the parking brake, and move the control levers inward to the neutral

operating position. Engage the PTO and move both control lever slowly into the slow reverse position; the PTO should disengage and the

mower deck should stop until one or both of the control levers is moved to the neutral or forward

position.

SECTION 3: ADJUSTMENTS

ADJUSTING THE OPERATORS SEAT

• To adjustthe positionof the seat, move and hold

the seat adjustment lever toward the left. Slide the seat forward or rearward to the desired

position;then release the adjustmentlever. Make sure seat is locked into positionbeforeoperating

ADJUSTING RH & LH DRIVE CONTROL LEVERS The RH and LH drive control levers can be adjusted

up or down and fore-and-aft for the comfort of the

operator. The drive control levers can be placed in either of two height positions, and/or can be moved

forward or rearward within the range of the slot in

each control lever mounting bracket.

To adjust the drive control lever height, proceed as follows:

Remove the flange lock nut, flat washer, and hex screw securing the lever to the pivot bracket.

While supporting the control lever to keep it from

falling, remove the hex insert flange lock nut and

shoulder screw from the bottom of the control lever and pivot bracket. Refer to Figure 21.

° Reposition the control lever to align with the other

set of holes in the pivot bracket and insert the shoulder screw removed earlier. Fasten with the

hex insert flange lock nut and tighten until snug.

o Insert the hex screw w/washer through the

control lever slot and the pivot bracket.Thread the flange lock nut onto the screw, but do not tighten

now.

If you are going to adjust the control levers

forward or rearward, proceed to the next step. If not, fully the flange lock nut.

Push the oil drain valve in slightly, then rotate counterclockwise and pull outward to begin draining oil. See Figure 22.

After draining the oil, remove the drain hose, push the drain valve in and rotate clockwise to

lock in the dosed position. Push the protective

cap back onto the drain valve.

HYDROSTATIC TRANSMISSION MAINTENANCE

The zero turn tractor is equipped with dual integrated hydrostatic pumps, motors, and transaxles that are

sealed and do not require regular maintenance. All service work on the hydrostatic transmissions

should be performed by your Cub Cadet dealer.

Model RZT 54 ONLY

The model RZT54 is equippedwith a transmissionoil expansion reservoir. Under normal operating condi-

tions,the oil level in the expansion reservoir does not need to be checked and no additional oil is needed.

if checking the reservoir oil level, proceed as follows:

IMPORTANT: Check the oil level ONLY before starting the tractor when the transmission oil is

fully cooled,

• Pivotthe operator'sseat forward

• Clean the reservoircap and the area aroundthe

cap to prevent debris from contaminating the transmissionoil. See Figure23.

RZT 54 ONLY

Pivotseat

Figure 23

• Turn the reservoir cap counterclockwise to re- move, then check the oil level in the reservoir. Oil

should be visible at the bottom of the cup, but the oil level must NOT be above 1/4" from the bot-

tom of the cup. DO NOT FILL THE RESERVOIR.

= If necessary to add oil because of some type of

leakage, use a quality 20W50 motor oil and add only enough oil to bring the level within 1/4" of the bottom of the reservoir. Reinstall the cap and fully

tighten.

GENERAL BATFERY INFORMATION

i_ WARNING:

• Should battery acid accidentally splatter into the

eyes or onto the skin, rinse the affected area

immediately with clean cold water. If there is any

further discomfort, seek prompt medical attention.

• If acid spills on clothing, first dilute it with clean water, then neutralize with a solution of ammonia/

water or baking soda/water.

• NEVER connect (or disconnect) battery charger clips to the battery while the charger is turned on,

as it can cause sparks.

• Keep all sources of ignition (cigarettes, matches, lighters) away from the battery. The gas gener-

ated during charging can be combustible.

• As a further precaution, only charge the battery in

a well ventilated area.

• Always shield eyes and protect skin and clothing

when working near batteries.

WARNING: Batteries contain sulfuric acid

and may emit explosive gases. Use extreme caution when handling batteries.

Keep batteries out of the reach of children.

BATTERY REMOVAL

WARNING: Battery posts, terminals and

related accessories contain lead and lead

compounds. Wash hands after handling.

The battery is located on the right!rearof the tractor

beneath the seat box frame. To remove the battery:

• Remove the two hex tapping screws from the bat- tery holddown bracket and remove the bracket.

Use care to avoid losing the trim strip from the bottom of the bracket. See Figure 24.

• Remove the hex cap screw and sems nut secur- ing the black negative battery lead to the negative

battery post (marked NEG). Move the cable away from the negative battery post.

• Remove the hex cap screw and sems nut secur-

ing the red positive battery lead to the positive battery post (marked POS).

• Carefully lift the battery out of the tractor.

Install the battery by repeating the above steps in the reverse order.

WARNING: Always connect the positive

lead to the battery before connecting the

negative lead. This will prevent sparking or possible injury from an electrical short

caused by contacting the tractor body with tools being used to connect the cables.

CHARGING THE BA'n'ERY

Test and, if necessary, recharge the battery after the tractor has been stored for a period of time.

• A voltmeter or load tester should read 12.6 volts (DC) or higher across the battery terminals.

• Charge the battery with a 12-volt battery charger at a MAXIMUM rate of 10 amps.

Voltmeter State of Charging

Reading Charge Time

12.7 100% Full Charge

12.4 75% 90 Min.

12.2 50% 180 Min.

12.0 25% 280 Min.

BATTERY MAINTENANCE

The battery is filled with battery acid and then sealed at the factory. However, even a "maintenance free" battery requires some maintenance to ensure its proper life cycle.

• Spray the terminals and exposed wire with a battery terminal sealer, or coat the terminals with

a thin coat of grease or petroleum jelly, to protect against corrosion.

• Always keep the battery cables and terminals clean and free of corrosion.

• Avoid tipping. Even a sealed battery will leak electrolyte when tipped.

BATTERY STORAGE

° When storing the tractor for extended periods,

disconnect the negative battery cable, it is not necessary to remove the battery.

• All batteries discharge during storage. Keep the

exterior of the battery clean, especially the top. A dirty battery wilt discharge more rapidly.

• The battery must be stored with a full charge. A

discharged battery can freeze sooner than a

charged battery. A fully charged battery will store

longer in cold temperatures than hot.

• Recharge the battery before returning to service.

Although the tractor may start, the engine charging system may not fully recharge the battery.

SERVICING ELECTRICAL SYSTEM

A fuse is installed to protect the tractor's electrical system from damage caused by excessive amper-

age. Always use the same capacity fuse for

replacement. If the electrical system does not func-

tion, check for a blown fuse. See Figure 25

GOOD BAD

Figure 25

If you have a recurring problem with blown fuses, have the tractor's electrical system checked by your

Cub Cadet dealer.

Relays and Switches

There are several safety switches in the electrical system. If a function of the safety interlock system described earlier is not functioning properly, have the electrical system checked by your Cub Cadet dealer.

LUBRICATION

• Using a pressure lubricating gun, lubricate the front castor axles and pivot axle with Cub Cadet 251H EP grease after every 10 hours of service.

• Refer to the "MOWER DECK" section later in this manual for deck lubrication procedures.

° Periodically lubricate all other pivot points with a

quality lubricating oil.

TIRE MAINTENANCE

Check the tire air pressure after every 50 hours of operation or weekly. Keep the tires inflated to the rec-

ommended pressures. Improper inflation witl shorten

the tire service life. See the tire side wall for proper

inflation pressures. Observe the following guidelines:

• Do not inflate a tire above the maximum pressure shown on the sidewall of the tire.

• Do not reinflate a tire that has been run flat or seriously under inflated. Have a qualified tire

mechanic inspect and service the tire.

USING THE TRANSMISSION BYPASS RODS If for any reason the tractor will not drive or you wish

to move the tractor, the two hydrostatic transmis- sions are equipped with a bypass rod that will allow

youto manually movethe tractorshort distances.

_ WARNING: Do not tow the tractor, even

with the bypass rod engaged. Serious transmission damage will result from doing so.

• From just in front of the two rear tires, locate the transmission bypass rods. See Figure 26.

• Pull one rod toward the front of the tractor until the flange on the rod is forward of the keyhole

slot in the frame assembly.

° Lower the bypass rod into the keyhole slot and

release so the rod flange is against the front of

the frame bracket.

° Repeat the above procedure to engage the other

bypass rod.

- After moving the tractor, disengage both bypass rods. Lift the rod and guide the flange of the rod

back through the larger circular opening of the keyhole, then release the rod.

IMPORTANT: The tractor will not drive with the

bypass rods in the engage position.

TRACTOR CREEPING Creeping is the slight forward or backward movement

of the tractorwhen the engine is running at high idle

and the drive control levers are in the neutral position. If after operating the tractor for some time, it begins to

creep while in the neutral position, adjust the transmission control rods as follows.

• Place the front of the tractor against an immovable object (e.g. wall, post, etc.).

• Jack up the rear of the tractor so that both rear wheels are approximately one inch of the ground.

• With the engine running at high idle and the drive control levers opened out in the neutral position,

and the parking brake disengaged, check the rear wheels for rotation.

If only one wheel is rotating, locate the transmis- sion controlrod beneath the frame at the front of

the rear tire. If both wheels rotate, locate both control rods. See Figure27.

• Ifthe rotation stops, adjust the ferrule up or down the control rod as necessary to align with the hole in the transmission control arm, Re-insert the

ferrule into the hole in the control arm and secure

with the internal cotter pin.

• If necessary, repeat the previous two steps to adjust the other transmission control rod.

• Lower the tractor and remove the jack.

TRACTOR HIGH SPEED TRACKING

If the tractor tracks to one side withboth drive control levers fully forward, adjust the control levers as

follows:

• Check for proper and balanced air pressure in both front and rear tires.Refilltiresif necessary.

• Perform the first three steps in the previous sub- section,Tractor Creeping, to verifythat the tractor

TRACTOR STORAGE

If your tractor is not going to be operated for an extended period of time (thirty days to approximately

six months), the tractor should be prepared for stor- age. Store the tractor in a dry and protected location. If stored outside, cover the tractor (including the tires)

to protect it from the elements. The procedures out-

lined below should be performed whenever the tractor is placed in storage.

1. Change the engine oil and filter following the instructions provided in the engine manual packed with this manual.

_ WARNING: Never store the tractor with

fuel in the tank indoors or in poorly ven- tilated enclosures, where fuel fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer, etc.

_ ARNING: Fuel left in the fuel tank dete-

riorates and will cause serious starting problems.

If storing the tractor for 30 days or more:

To prevent gum deposits from forming inside the

engine's carburetor and causing possible malfunc- tion of the engine, the fuel system must be either completely emptied, or the gasoline must be treated with a stabilizer to prevent deterioration.

Using a fuel stabilizer: * Read the product manufacturer's instructions

and recommendations.

- Add to clean, fresh gasoline the correct amount

of stabilizer for the capacity (approximately 3 gallons) of the fuel system.

• Fill the fuel tank with treated fuel and run the

engine for 2-3 minutes to get stabilized fuel into

the carburetor.

Emptying the fuel system:

• Prior to putting the tractor in storage, monitor

fuel consumption with the goal of running the fuel tank empty.

• Run the engine until it begins to stall. Use the choke to keep the engine running until all fuel in

the carburetor has been exhausted.

• Referring to the engine manual, drain the fue! from the carburetor bowl.

3. Clean the engine and the entire tractor

thoroughly.

4. Fully charge the battery, then disconnect the neg- ative cable at the battery to prevent possible

discharge. Recharge the battery periodically when in storage. NOTE: Remove the battery if

exposed to prolonged periods of sub-freezing temperatures. Store in a cool dry/ocation where

temperatures are above freezing.

5. Lubricate a_Jlubrication points.

NOTE: We do not recommend the use of a pressure washer or garden hose to clean your tractor. They may

cause damage to electrical components; spindles;

pulleys; bearings; or the engine. The use of water will

result in shortened life and reduce serviceability.

REMOVING THE TRACTOR FROM STORAGE

• Check the engine oil.

• Fully charge the battery and inflate the tires to the recommended pressure.

• If drained before storing, fill the fuel tank with

clean, fresh gasol}ne.

• Add clean, fresh fuel.

• Start the engine and allow to idle for a few minutes to ensure engine is operating properly.

• Drive the tractor without a lead to make certain all the tractor systems are functioning properly.

LEVELING THE MOWER DECK

When correctly adjusted the mower deck should be level side to side, and the front of the deck should be

approximately 1/4 inch lower than the rear of deck. Side to Side Leveling

If the cutting deck appears to be mowing unevenly, a side to side adjustment can be performed. Adjust if

necessary as follows:

• With the tractor parked on a firm, level surface, place the deck lift handle in the top notch (highest posiUon) and rotate both outer blades so that they

are perpendicutar to the tractor frame.

• Lower the deck to the middle height position.

• Measure the distance from the outside left blade tip to the ground and the distance from the outside right blade tip to the ground. The

measurements should be equal. If they're not, proceed to the next step.

• Comparing the two measurements, determine whether the left side of the deck must be raised

or lowered.

• Loosen, but do not remove, the hex cap screw on the left deck hanger bracket. Refer to Figure 33.

• Level the deck by using a wrench to turn the adjustment gear (found immediately behind the hex cap screw just loosened) clockwise to raise

the left side of the deck, or counterclockwise to

lower the left side of the deck. See Figure 33.

• The deck is properly leveled when reft and right blade tip measurements are equal.

• Retighten the hex cap screw on the left deck hanger bracket when proper adjustment is

achieved.

Front to Back Leveling.

The front of the deck should be approximately 1/4

inch lower than the rear of the deck. Adjust if neces-

sary as follows:

• With the deck raised off of the ground, rotate the outer blades so that they are parallel to the frame

of the tractor.

• If the side to side leveling was done correctly, measuring just the right blade should be

acceptable to attain the correct back to front pitch of the deck.

• Measure the distance from the front tip of the

blade to the ground and the distance from the rear tip to the ground. The front distance should be approximately 1/4 inch less than the rear. If it is not, proceed to the next step.

• From the front of the tractor, loosen the outer hex nuts on the deck front hanger rod and turn them

away from the inner nuts. See Figure 34.

• If the front of the deck was too low, turn the inner hex nuts clockwise against the hanger bracket to

shorten the front hanger rod and raise the front of

the deck. See Figure 34.

• If the front of the deck was too high, turn the hex nuts counterclockwise to lengthen the front hanger rod and lower the front of the deck.

IMPORTANT: The deck front hanger rod should be at the front of the slots of the front deck

bracket, if one side of the rod is not at the front of its slot, turn the inner hex nut on that side until

rod just touches the front of the slot. Then re- measure and re-adjust the front hanger rod as necessary.

When the correct pitch of the deck is acquired, secure the inner hex nuts with a wrench and

tJghten the outer hex nuts against the inner hex nuts to lock them in the adjusted position.
