SAFETY INSTRUCTIONS

Driving on Slopes

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 you 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 direction.

• 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 equipment,

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.

• Avoid starting or stopping on a slope. If tires

lose traction, disengage the blades and proceed slowly straight down the slope.

Mow up and down, not side-to-side

Be extra cautious when driving on slopes

8003-004

8011-519

• If machine stops while going uphill, disen-

gage blades and back down slowly.

• Do not turn on slopes unless necessary, and

then, turn slowly and gradually downhill, if possible.

SAFETY INSTRUCTIONS

Children

• Serious accidents may occur if you fail to be

on guard for children in the vicinity of the machine. Children are often attracted to the machine 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 prevent risk-free maneuvering of the machine.

Never allow children to operate the machine

OPERATION

HOW TO USE YOUR MOWER

TO SET PARKING BRAKE (See Fig. 3)

Your mower is equipped with an operator presence system. When the engine is running, any attempt by the operator to leave the seat without first setting the park brake will shut off the engine.

• Pull park brake lever up to engage the park brake. Make sure the lever is secured to the right.

DECK BLADES

• To stop the deck blades, press down on the PTO Switch into the disengaged position.

ENGINE

• Move throttle control to slow position.

NOTE: Failure to move the throttle control to

slow position and allow engine to idle before stopping may cause engine to “backfire”.

• Turn ignition key to “OFF” position and remove key. Always remove key when leaving the mower to prevent unauthorized use.

• Never use choke to stop engine.

IMPORTANT: LEAVING THE IGNITION

SWITCH IN ANY POSITION OTHER THAN “OFF” WILL CAUSE THE BATTERY TO BE DISCHARGED, (DEAD).

WARNING

Always stop mower completely before leaving the operators position; to empty a grass catcher, etc.

OPERATION

TO USE THROTTLE CONTROL (See Fig. 3)

Always operate engine at full throttle. The

Throttle control is equipped with a choke detent. Pressing the throttle control all of the way forward will choke the engine. For full throttle, press throttle control forward until you feel resistance.

• Operating engine at less than full throttle reduces the battery charging rate

• Full throttle offers the best mower performance.

TO USE CHOKE CONTROL (See Fig. 3)

Use choke control whenever you are starting a cold engine. Do not use to start a warm engine.

• To choke, pull up on the choke knob.

• To take out of choke, push down on the choke knob.

TO MOVE FORWARD AND BACKWARD (See Fig. 4)

IMPORTANT: CONTROL LEVERS RETURN

TO NEUTRAL WHEN RELEASED. THIS MAY CAUSE A SUDDEN STOP OF THE MOWER.

The direction and speed of movement is controlled by the control levers on either side of the mower.

The left lever controls the flow of oil in the left IZT (Integraded Zeroturn Transaxle) to the left wheel. The right lever controls the flow of oil in the right IZT to the right wheel.

OPERATION

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. Fig. 4 and 4A.

By moving the levers an equal amount forward or back the machine will move in a straight line in that direction. Fig. 4 and 4A

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 position, this will slow the rotation of the right wheel and cause the machine to turn in that direction.

CZ-7

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 determined by which lever is pulled back beyond neutral. Thus left lever back, left zero turn and opposite for right zero turn.

Use extra care when using this maneuver the machine can spin very rapidly if one lever is positioned too far ahead of the other.

CAUTION

DO NOT apply excessive force to control levers or use to assist in dismounting unit. Misuse will result in bent control levers.

OPERATION

TO ADJUST THE DECK CUTTING HEIGHT (See Fig. 5)

The deck cutting height is obtained by pressing the foot pedal forward to lift the deck. To lower the deck, you apply pressure to the top side of the foot pedal and allow it to pivot while allowing the lift arm to rotate to the rear of the unit. To stop in a desired cutting position, rotate the foot pedal down into the notch in the height plate. The cutting height range is from 1 1/2" to 4 1/2" in 1/2" increments. The heights are measured from the ground up to the blade tip with the engine not running.

• The average lawn should be cut to 2 1/2" during the cool season and to over 3" during the hot months. For healthier and better looking lawns, mow often and after moderate growth.

• For best cutting performance, grass over 6 inches in height should be mowed twice. Make the first cut relatively high; the second to the desired height.

OPERATION

TO ADJUST ANTI-SCALP ROLLERS (See Figure 6)

Anti-scalp rollers are properly adjusted when they are just slightly off of the ground when the deck is at the desired cutting height in the operating position. Anti-scalp rollers then keep the deck in the proper position to help prevent scalping in most terrain conditions.

NOTE: Adjust Anti-scalp rollers with the mower

on a flat level surface.

• Adjust the deck to the desired cutting height (see “TO ADJUST DECK CUTTING HEIGHT” in the operation section of this manual).

• Using a 3/4" wrench and a 9/16" wrench, remove the nut and shoulder bolt from the anti-scalp roller.

• Lower the anti-scalp roller to the ground, and raise it up to the next highest hole.

• Replace and tighten the nut and shoulder bolt.

• Be sure to adjust all of the anti-scalp rollers to the same position.

• Be sure to readjust the anti-scalp rollers if the cutting height is changed.

• Refer to you Engine Owners Manual for correct oil level.

• To change engine oil, see the Customer Responsibilities section of this manual.

ADD GASOLINE

• Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to ensure fuel freshness.

IMPORTANT: WHEN OPERATING IN

TEMPERATURES BELOW 32° F. (0° C.), USE FRESH, CLEAN WINTER GRADE GASOLINE TO HELP INSURE GOOD COLD WEATHER STARTING.

CAUTION

Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it the run until the fuel lines and carburetor are empty. Use fresh fuel the next season. See Storage Instructions for additional information. Never use engine or carburetor cleaners in the fuel tank or permanent damage may occur.

WARNING

Fill to bottom of filler neck. Do not over fill. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame.

OPERATION

TO START ENGINE (See Fig. 3)

When starting the engine for the first time or if the engine has run out of fuel, it will take extra cranking time to move fuel from the tank to the engine.

• Be sure IZT (Integraded Zeroturn Transaxle) bypass linkages are in the drive position.

• Sit on the seat in the operators position, release park brake lever.

• Check to be sure the PTO switch is disengaged.

• Move the throttle control to the choke position.

• For a warm engine start, the choke control may not be needed

NOTE: Before starting, read the warm and cold

starting procedures below.

• Insert key into the ignition and turn the key clockwise to “START” position and release the key as soon the engine starts. Do not run the starter continuously for more than 15 seconds per minute. If the engine does not start after several attempts, push the throttle control into the choke position, wait a few minutes and try again. If the engine still does not start, move the throttle control back into the fast position and retry.

WARM WEATHER STARTING (50° F and above)

• When the engine starts, slowly pull the throttle control back until the engine begins to run smoothly. If the engine starts to run roughly, press the throttle control back forward to choke the engine for a few seconds. Then continue to pull the throttle control back to the fast position.

• The PTO switch and ground drive can now be used. If the engine does not accept the load, restart the engine and allow it to warm up for one minute using the choke as described above.

OPERATION

COLD WEATHER STARTING (50° F and below)

• When the engine starts, slowly pull the throttle control back until the engine

begins to run smoothly. Continue to pull back on the throttle control in small steps allowing the engine to accept small changes in speed and load, until the throttle control is completely in the fast position. If the engine starts to run roughly, press the throttle control back forward to choke the engine for a few seconds. Then continue to pull the throttle control back slowly to the fast position. This may require an engine warm up period from several seconds to several minutes, depending on the temperature.

MOWING TIPS

• The cutting deck should be properly leveled for best mowing performance. See “TO LEVEL DECK” in the Service and Adjustment section of this manual.

• The left hand side of the deck should be used for trimming.

• Drive so that clippings are discharged onto the area that has been cut. Have the cut area to the right of the mower. This will result in more even distribution of clippings and a more uniform cut.

• If grass is extremely tall, it should be mowed twice to reduce load and possible fire hazard from dried clippings. Make first cut relatively high; second to desired height.

• Do not mow grass when it is wet. Wet grass will plug the deck and leave undesirable clumps. Allow grass to dry before mowing.

• Always operate engine at full throttle when mowing to assure better mowing performance and proper discharge of material. Regulate ground speed by going slow enough to allow proper deck cutting performance as well as the quality of cut desired. When operating attachments, select a ground speed that will suit the terrain and give best performance of the attachment being used.

STORAGE

ENGINE

FUEL SYSTEM

IT IS IMPORTANT TO PREVENT GUM DEPOSITS FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH AS CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT ALCOHOL BLENDED FUELS (CALLED GASOHOL OR USING ETHANOL OR METHANOL) CAN ATTRACT MOISTURE WHICH LEADS TO SEPARATION AND FORMATION OF ACIDS DURING STORAGE. ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM OF AN ENGINE WHILE IN STORAGE.

• Drain the fuel tank.

• Start the engine and let it run until the fuel lines and carburetor are empty.

• Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer.

ENGINE OIL

Drain oil (with engine warm) and replace with clean engine oil. (See "ENGINE" in the Customer Responsibilities section of this manual).

CYLINDER(S)

• Remove spark plug(s).

• Pour one ounce of oil through spark plug hole(s) into cylinder(s).

• Install plugs.

• Turn ignition key to "START" position for a few seconds to distribute oil.

• Replace with new spark plug(s).

OTHER

• Do not store gasoline from one season to another.

• Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems.

• If possible, store your mower indoors and cover it to give protection from dust and dirt.

• Cover your mower with a suitable protective cover that does not retain moisture. Do not use plastic. Plastic cannot breathe which allows condensation to form and will cause your mower to rust.
