2.
Only allow responsible individuals familiar with the instructions to operate the machine. Know the controls and how to stop the machine quickly.
3.
Do not put hands or feet under the cutting deck or near rotating parts.
4.
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.
10. 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. Turn off blades when not mowing.
12. 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.
4
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 closefitting 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.
19. 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 pulled 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 lap 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.
II.
SLOPE OPERATION
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 15° as shown on the slope gauge, do not operate this unit on that area or serious injury could result.
5
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 backwards, 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 counterweights with attachments to improve stability.
Use extra care with grass catchers or other attachments. 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.
3.
Before and when backing up, look behind and
down
for small children.
4.
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
1.
Use extreme care in handling gasoline 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 engine 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 other 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.
2.
Never run a machine inside a closed area.
3.
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 plug to prevent accidental starting.
5.
Check the blade and engine mounting bolts at frequent 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 allow 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 immediately following the draining of fluids.
c.
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 Environmental Protection Agency regulations when disposing of oil, fuel, coolant, brake fluid, filters, 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.
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.

SECTION 2: OPERATION
GENERAL SAFETY
• RECEIVE INSTRUCTION - Read the operator’s manual. Learn to operate this machine SAFELY.
Don’t risk INJURY or DEATH. Allow only those who have become competent in its usage to operate this tractor.
• Familiarize yourself with the operations of all the instruments and controls.
• 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
P. MODEL RZT 54 ONLY - Transmission Oil
Expansion Reservoir
The transmission oil expansion reservoir is connected by hoses to the RH and LH transmission assemblies, and is located beneath the seat box. The function of the reservoir is to hold the natural expansion of transmission oil that occurs as the transmission warms up during operation. DO NOT FILL
THE RESERVOIR.
Under normal operating conditions, no oil should be added to the reservoir. The COLD oil level should be no higher than approximately 1/4" (the "Full Cold" mark) above the bottom of the reservoir.
NOTE:
Prior to the initial operation of the tractor, the oil level in the reservoir may be slightly higher than the maximum due to air in the oil lines. Operation of the tractor will eventually purge the air from the lines and the oil level will settle to the maximum.
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.

13
• 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 interlock system will shut off the PTO and the mower blades will stop if both drive control 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 operate the tractor if any part of the interlock system is malfunctioning. Periodically check the functions of the interlock system for proper operation.

• Turn the ignition key clockwise to the “START” position and release it as soon as the engine starts; however, do not crank the engine continuously for more than 5 seconds at a time. If the
14
engine does not start within this 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 closed as this will cause flooding and make starting 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 disabled tractor, as far from the battery as possible.
• Start the disabled tractor following the normal starting instructions previously provided; then
15 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 outward in the neutral position.
• Engage the parking brake.
• Move the throttle control to the SLOW position and allow the engine to idle for about one minute.
• Turn the ignition key to the “OFF” position and remove the 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 because a zero turn tractor is more maneuverable, getting used to operating the control levers takes some practice.
We strongly recommend that you locate a reasonably large, level and open "practice area" where there are no obstructions, pedestrians, or animals. You should practice operating the tractor for 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 Tractor." Practice until you are confident that you can safely operate the tractor.
DRIVING THE TRACTOR
WARNING: Avoid sudden starts, excessive 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.

STOPPING THE TRACTOR
• Move both drive control levers to the neutral position to stop the motion of the tractor.
• Push the PTO switch downward to the disengaged position.
• Use the deck lift handle to raise the deck to its highest position.
• 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.
18
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 turf, if possible, change the direction that the strips are mowed by approximately 45° for the next and each subsequent mowing.
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 working properly. If a safety circuit is not working as designed, contact you Cub Cadet dealer to have the tractor inspected. DO NOT operate the tractor if any safety circuit is not functioning properly. To check the safety 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 disengaged position and engage the parking brake.
Start the engine and move one of the drive control levers from the fully outward neutral position.
The engine should stop running. Repeat the procedure with the opposite control lever.
• Move both control levers fully outward in the neutral 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 neutral 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.

• Turn the reservoir cap counterclockwise to remove, 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 bottom 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 BATTERY INFORMATION
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 generated 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/rear of the tractor beneath the seat box frame. To remove the battery:
• Remove the two hex tapping screws from the battery holddown bracket and remove the bracket.

• 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 recommended pressures. Improper inflation will 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 transmissions are equipped with a bypass rod that will allow you to manually move the tractor short 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 tractor when 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 transmission control rod beneath the frame at the front of the rear tire. If both wheels rotate, locate both control rods. See Figure 27.

• Remove the internal cotter pin securing the ferrule to the transmission control arm and withdraw the ferrule. Wheel rotation should stop.
If it does not, contact your Cub Cadet dealer.
• If the 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 with both drive control levers fully forward, adjust the control levers as follows:
• Check for proper and balanced air pressure in both front and rear tires. Refill tires if necessary.
• Perform the first three steps in the previous subsection, Tractor Creeping, to verify that the tractor is not creeping. If creeping, adjust following the instructions in that sub-section.
• Recheck the tracking after making any adjustments to the transmission control rods.
• If uneven tracking persists, note which direction the tractor is tracking.
- If the tractor tracks to the right, adjust the control lever stop bolt on the left side.
- If the tractor tracks to the left, adjust the control lever stop bolt on the right side.
• Locate the applicable stop bolt on the left or right console. See Figure 28.
• Tighten the jam nut against the console and reposition the control lever if necessary.
TRANSMISSION DRIVE BELT
If the transmission drive belt becomes worn and causes the drive transmissions to slip, the drive belt must be replaced. To replace the drive belt, proceed as follows:
• Remove the deck drive belt from the PTO clutch on the bottom of the engine following the instructions in Deck Removal, SECTION 5: MOWER
DECK.
• From beneath the rear of the tractor, insert a 3/8 inch drive ratchet into the square hole of the drive idler bracket. See Figure 29.

• Reinstall the deck drive belt.
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 storage. 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 outlined 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 ventilated enclosures, where fuel fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer, etc.
WARNING: Fuel left in the fuel tank deteriorates and will cause serious starting problems.
2.
If storing the tractor for 30 days or more:
To prevent gum deposits from forming inside the engine’s carburetor and causing possible malfunction 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 fuel from the carburetor bowl.
3.
Clean the engine and the entire tractor thoroughly.
4.
Fully charge the battery, then disconnect the negative 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 location where temperatures are above freezing.
5.
Lubricate all lubrication 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 gasoline.
• 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 load 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 position) and rotate both outer blades so that they are perpendicular 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.
Front to Back Leveling.
The front of the deck should be approximately 1/4 inch lower than the rear of the deck. Adjust if necessary 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 remeasure 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 tighten the outer hex nuts against the inner hex nuts to lock them in the adjusted position.

ADJUSTING THE GAUGE WHEELS AND ROLLERS
WARNING: Keep hands and feet away from the discharge opening of the cutting deck.
Model RZT50 Gauge Wheels
NOTE:
The deck gauge wheels are an anti-scalp feature of the deck and are not designed to support the weight of the cutting deck.
The mower deck cutting height can be set in any of six height settings using the tractor’s deck lift handle.
The deck heights range from 1-1/2" to 4". For the model RZT50, the deck gauge wheel position should be approximately 1/4 to 1/2 inch above the ground when the deck is set in the desired height setting.
Using the lift handle, set the deck in the desired height setting, then check the gauge wheel distance from the ground below. If necessary adjust as follows:
• Visually check the distance between the front gauge wheels and the ground. If the gauge wheels are near or touching the ground, they should be raised. If more than 1/2" above the ground, they should be lowered.
• Remove the lock nut securing one of the front gauge wheel shoulder screws to the deck.
Remove the gauge wheel and shoulder screw.
See Figure 35.
• Insert the shoulder screw into the one of four index holes in the front gauge wheel bracket that will give the gauge wheel a 1/4 to 1/2 inch clearance with the ground.
• Note the index hole of the just adjusted wheel, and adjust the other gauge wheels into the respective index holes of the other gauge wheel brackets on the deck.

Model RZT54 Gauge Wheels and Rollers
The front gauge wheels on the RZT54 mower deck are an anti-scalp feature, and should not ride on the ground. The front gauge wheels should be approximately 1/4 to 1/2 inch above the ground when the deck is set in the desired height setting.
The rear deck rollers can be set in either the low or high position.
29
Using the lift handle, set the deck in the desired height setting, then check the gauge wheel distance from the ground below. If necessary adjust the front gauge wheels as follows:
• Visually check the distance between the front gauge wheels and the ground. If the gauge wheels are near or touching the ground, they should be raised. If more than 1/2" above the ground, they should be lowered.
• Remove the lock nut securing one of the front gauge wheel shoulder screws to the deck.
Remove the gauge wheel and shoulder screw.
Refer to Figure 35.
• Insert the shoulder screw into the one of four index holes in the front gauge wheel bracket that will give the gauge wheel a 1/4 to 1/2 inch clearance with the ground.
• Note the index hole of the just adjusted wheel, and adjust the other front gauge wheel into the respective index hole of the other front gauge wheel bracket.
The position on the rear deck rollers is generally not changed. In the low position the rollers will roll the grass. In the high position, the rollers are in a storage position and do little or no rolling of the grass.
Change the roller position as follows:
• Remove the cotter pin from the left end of the roller shaft. See Figure 36.
• Slide the roller shaft to the right and remove the rollers as the shaft is fully withdrawn from the right rear roller bracket. See Figure 36.

OWNER’S WARRANTY RESPONSIBILITIES:
As the lawn mower owner, you are responsible for performance of the required maintenance listed in your owner’s manual. MTD Consumer Group Inc. recommends that you retain all receipts covering maintenance on your lawn mower, but MTD Consumer Group Inc. cannot deny warranty solely for the lack of receipts.
As the lawn mower owner, you should however be aware that MTD Consumer Group Inc. may deny you warranty coverage if your lawn mower or a part has failed due to abuse, neglect, or improper maintenance or unapproved modifications.
You are responsible for presenting your lawn mower to MTD Consumer Group Inc’s distribution center or service center as soon as the problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days. If you have a question regarding your warranty coverage, you should contact the MTD Consumer Group Inc. Service Department at 1-800-800-7310.
GENERAL EMISSIONS WARRANTY COVERAGE:
MTD Consumer Group Inc. warrants to the ultimate purchaser and each subsequent purchaser that the lawn mower is: Designed, built and equipped so as to conform with all applicable regulations; and free from defects in materials and workmanship that cause the failure of a warranted part to be identical in all material respects to that part as described in MTD Consumer Group Inc’s application for certification.
The warranty period begins on the date the lawn mower is delivered to an ultimate purchaser or first placed into service. The warranty period is two years.
Subject to certain conditions and exclusions as stated below, the warranty on emission-related parts is as follows:
1. Any warranted part that is not scheduled for replacement as required maintenance in the written instructions supplied, is warranted for the warranty period stated above. If the part fails during the period of warranty coverage, the part will be repaired or replaced by MTD Consumer Group Inc. according to subsection (4) below. Any such part repaired or replaced under warranty will be warranted for the remainder of the period.
2. Any warranted part that is scheduled only for regular inspection in the written instructions supplied is warranted for the warranty period stated above. Any such part repaired or replaced under warranty will be warranted for the remaining warranty period.

Any warranted part that is scheduled for replacement as required maintenance in the written instructions supplied is warranted for the period of time before the first scheduled replacement date for that part.

10. Add-on or modified parts that are not exempted by the Air Resources Board may not be used. The use of any non-exempted add-on or modified parts by the ultimate purchaser will be grounds for disallowing a warranty claim. MTD Consumer Group Inc. will not be liable to warrant failures of warranted parts caused by the use of a non-exempted add-on or modified part.
WARRANTED PARTS:
The repair or replacement of any warranted part otherwise eligible for warranty coverage may be excluded from such warranty coverage if MTD Consumer Group
Inc. demonstrates that the lawn mower has been abused, neglected, or improperly maintained, and that such abuse, neglect, or improper maintenance was the direct cause of the need for repair or replacement of the part . That notwithstanding, any adjustment of a component that has a factory installed, and properly operating, adjustment limiting device is still eligible for warranty coverage.
