All drivers should seek and obtain professional and   practical instruction.   22. Always wear substantial footwear and trousers.   Never operate when barefoot or wearing sandals.   23. Before using, always visually check that the blades   and blade hardware are present, intact, and secure.   Replace worn or damaged parts.   3. Only allow responsible adults, who are familiar with   the instructions, to operate the unit (local regulations   can restrict operator age).   4. Clear the area of objects such as rocks, toys, wire,   etc., which could be picked up and thrown by the   blade(s).   24. Disengage attachments before: refueling, removing   an attachment, making adjustments (unless the   adjustment can be made from the operator’s posi-   tion).   5. Be sure the area is clear of other people before mow-   ing. Stop the unit if anyone enters the area.   6. Never carry passengers.   25. When the machine is parked, stored, or left unattend-   ed, lower the cutting means unless a positive   mechanical lock is used.   7. Do not mow in reverse unless absolutely necessary.   Always look down and behind before and while travel-   ling in reverse.   26. Before leaving the operator’s position for any reason,   engage the parking brake (if equipped), disengage   the blades (PTO), stop the engine, and remove the   key.   8. Never direct discharge material toward anyone. Avoid   discharging material against a wall or obstruction.   Material may ricochet back toward the operator. Stop   the blade(s) when crossing gravel surfaces.   9. Do not operate the machine without the entire grass   catcher, discharge guard (deflector), or other safety   devices in place and operational.   27. To reduce fire hazard, keep the unit free of grass,   leaves, & excess oil. Do not stop or park over dry   leaves, grass, or combustible materials.   28. It is a violation of California Public Resource Code   Section 4442 to use or operate the engine on or near   any forest-covered, brush-covered, or grass-covered   land unless the exhaust system is equipped with a   spark arrester meeting any applicable local or state   laws. Other states or federal areas may have similar   laws.   10. Slow down before turning.   11. Never leave a running unit unattended. Always disen-   gage the blades (PTO), set parking brake, stop   engine, and remove keys before dismounting.   12. Disengage blades (PTO) when not mowing. Shut off   engine and wait for all parts to come to a complete   stop before cleaning the machine, removing the grass   catcher, or unclogging the discharge guard.   13.

If you cannot   back up the slope or if you feel uneasy on it, do not operate   on it.   Never operate on slopes greater than 17.6 percent   (10°) which is a rise of 3-1/2 feet (106 cm) vertically in   20 feet (607 cm) horizontally.   Select slow ground speed before driving onto slope.   Use extra caution when operating on slopes with rear-   mounted grass catchers.   Mow across the face of slopes, not up and down,use   caution when changing directions and DO NOT   START OR STOP ON SLOPE.   Control of a walk-behind or ride-on machine sliding on a   slope will not be regained by the application of the brake.   The main reasons for loss of control are: insufficient tire   grip on the ground, speed too fast, inadequate braking, the   type of machine is unsuitable for its task, lack of awareness   of the ground conditions, incorrect hitching and load distri-   bution.   1. Mow across slopes, not up and down.   2. Watch for holes, ruts, or bumps. Uneven terrain could   overturn the unit. Tall grass can hide obstacles.   3. Choose a slow speed so that you will not have to stop   or change speeds while on the slope.   4. Do not mow on wet grass. Tires may loose traction.   5. Never mow down slopes.   CHILDREN   6. Avoid starting, stopping, or turning on a slope. If tires   lose traction (i.e. machine stops forward motion on a   slope), disengage the blade(s) (PTO) and drive slow   off the slope.   Tragic accidents can occur if the operator is not alert to the   presence of children. Children are often attracted to the unit   and the mowing activity. Never assume that children will   remain where you last saw them.   1. Keep children out of the mowing area and under the   watchful care of another responsible adult.   2. Be alert and turn unit off if children enter the area.   3. Before and during reverse operation, look behind and   down for small children.   4. Never carry children, even with the blade(s) off. They   may fall off and be seriously injured or interfere with   safe unit operation. Children who have been given   rides in the past may suddenly appear in the mowing   area for another ride and be run over or backed over   by the machine.   5. Never allow children to operate the unit.   6. Use extra care when approaching blind corners,   shrubs, trees, or other objects that may obscure   vision.   7. Keep all movement on slopes slow and gradual. Do   not make sudden changes in speed or direction,   which could cause the machine to rollover.   8. Use extra care while operating machines with grass   catchers or other attachments; they can affect the   stability of the unit. Do not use on steeps slopes.   9. Do not try to stabilize the machine by putting your   foot on the ground (ride-on units).   10. Do not mow near drop-offs, ditches, or embank-   ments. The mower could suddenly turn over if a   wheel is over the edge of a cliff or ditch, or if an edge   caves in.   11. Do not use grass catchers on steep slopes.   12. Do not mow slopes if you cannot back up them.   13. See your authorized dealer/retailer for recommenda-   tions of wheel weights or counterweights to improve   stability.   14. Remove obstacles such as rocks, tree limbs, etc.   15. Use slow speed. Tires may lose traction on slopes   even through the brakes are functioning properly.   16. Do not turn on slopes unless necessary, and then,   turn slowly and gradually uphill, if possible. Never   mow down slopes.   EMISSIONS   1. Engine exhaust from this product contains chemicals   known, in certain quantities, to cause cancer, birth   defects, or other reproductive harm.   2. Look for the relevant Emissions Durability Period and   Air Index information on the engine emissions label.   TOWED EQUIPMENT (RIDE-ON UNITS)   IGNITION SYSTEM   1. Tow only with a machine that has a hitch designed for   towing. Do not attach towed equipment except at the   hitch point.   1. This spark ignition system complies with Canadian   ICES-002.   2. Follow the manufacturer’s recommendations for   weight limit for towed equipment and towing on   slopes. See attaching a trailer under OPERATION.   3. Never allow children or others in or on towed equip-   ment.   4. On slopes, the weight of the towed equipment may   cause loss of traction and loss of control.   5. Travel slowly and allow extra distance to stop.   6. Do not shift to neutral and coast down hill.   3 Download from Www.Somanuals.com.

Extinguish all cigarettes, cigars, pipes, and other   sources of ignition.   2. Use only approved gasoline containers.   3. Never remove the gas cap or add fuel with the engine   running. Allow the engine to cool before refueling.   4. Never fuel the machine indoors.   5. Never store the machine or fuel container where there   is an open flame, spark, or pilot light such as near a   water heater or other appliance.   6. Never fill containers inside a vehicle or on a truck bed   with a plastic bed liner. Always place containers on   the ground away from your vehicle before filling.   7. Remove gas-powered equipment from the truck or   trailer and refuel it on the ground. If this is not possi-   ble, then refuel such equipment on a trailer with a   portable container, rather than from a gasoline dis-   penser nozzle.   8. Keep nozzle in contact with the rim of the fuel tank or   container opening at all times until fueling is com-   plete. Do not use a nozzle lock-open device.   9. If fuel is spilled on clothing, change clothing immedi-   ately.   10. Never over-fill the fuel tank. Replace gas cap and   tighten securely.   14. Replace faulty silencers/mufflers.   15. Maintain or replace safety and instruction labels as   necessary.   16. Use only factory authorized replacement parts when   making repairs.   17. Always comply with factory specifications on all set-   tings and adjustments.   18. Only authorized service locations should be utilized   for major service and repair requirements.   19. Never attempt to make major repairs on this unit   unless you have been properly trained. Improper   service procedures can result in hazardous operation,   equipment damage and voiding of manufacturer’s   warranty.   20. On multiple blade mowers, take care as rotating one   blade can cause other blades to rotate.   21. Do not change engine governor settings or over-   speed the engine. Operating the engine at excessive   speed can increase the hazard of personal injury.   22. Disengage drive attachments, stop the engine,   remove the key, and disconnect the spark plug wire(s)   before: clearing attachment blockages and chutes,   performing service work, striking an object, or if the   unit vibrates abnormally. After striking an object,   inspect the machine for damage and make repairs   before restarting and operating the equipment.   23. Never place hands near the moving parts, such as a   hydro pump cooling fan, when the tractor is running.   (Hydro pump cooling fans are typically located on top   of the transaxle).   11. Use extra care in handling gasoline and other fuels.   They are flammable and vapors are explosive.   12. If fuel is spilled, do not attempt to start the engine but   move the machine away from the area of spillage and   avoid creating any source of ignition until fuel vapors   have dissipated.   24. Units with hydraulic pumps, hoses, or motors: WARN-   ING: Hydraulic fluid escaping under pressure may   have sufficient force to penetrate skin and cause seri-   ous injury. If foreign fluid is injected into the skin it   must be surgically removed within a few hours by a   doctor familiar with this form of injury or gangrene   may result. Keep body and hands away from pin   holes or nozzles that eject hydraulic fluid under high   pressure. Use paper or cardboard, and not hands, to   search for leaks. Make sure all hydraulic fluid con-   nections are tight and all hydraulic hoses and lines   are in good condition before applying pressure to the   system. If leaks occur, have the unit serviced imme-   diately by your authorized dealer.   25. WARNING: Stored energy device. Improper release   of springs can result in serious personal injury.   Springs should be removed by an authorized techni-   cian.   26. Models equipped with an engine radiator: WARNING:   Stored energy device. To prevent serious bodily injury   from hot coolant or steam blow-out, never attempt to   remove the radiator cap while the engine is running.   Stop the engine and wait until it is cool. Even then,   use extreme care when removing the cap.   13. Replace all fuel tank caps and fuel container caps   securely.   Service & Maintenance   1. Never run the unit in an enclosed area where carbon   monoxide fumes may collect.   2. Keep nuts and bolts, especially blade attachment   bolts, tight and keep equipment in good condition.   3. Never tamper with safety devices. Check their proper   operation regularly and make necessary repairs if   they are not functioning properly.   4. Keep unit free of grass, leaves, or other debris build-   up. Clean up oil or fuel spillage. and remove any fuel-   soaked debris. Allow machine to cool before storage.   5. If you strike an object, stop and inspect the machine.   Repair, if necessary, before restarting.   6. Never make adjustments or repairs with the engine   running.   7. Check grass catcher components and the discharge   guard frequently and replace with manufacturer’s rec-   ommended parts, when necessary.   8. Mower blades are sharp. Wrap the blade or wear   gloves, and use extra caution when servicing them.   9. Check brake operation frequently. Adjust and service   as required.   10. Maintain or replace safety and instructions labels, as   necessary.   11. Do not remove the fuel filter when the engine is hot   as spilled gasoline may ignite. Do not spread fuel line   clamps further than necessary. Ensure clamps grip   hoses firmly over the filter after installation.   12.

To learn what combination and sequence   of controls to use for various tasks see the OPERATION section.   Ground Speed Levers   These levers control the ground speed of the rider. The   left lever controls the left rear drive wheel and the right   controls the right rear drive wheel.   Throttle Control   The throttle controls engine speed. Move the throttle for-   ward to increase engine speed and back to decrease   engine speed. Always operate at FULL throttle.   Moving a lever forward increases the FORWARD speed   of the associated wheel, and pulling back on a lever   increases the REVERSE speed.   Choke   Close the choke for cold starting. Open the choke once   the engine starts. A warm engine may not require chok-   ing. Move the lever forward to close the choke. Move the   lever back to open the choke.   The further a lever is moved away from the neutral posi-   tion the faster the drive wheel will turn.   See the OPERATION section for steering instructions.   6 Download from Www.Somanuals.com.

Position the cutting height selector pin on the   appropriate hole to achieve the desired cutting height.   Pull back on the small lift latch lever and large lever   simultaneously, and lower the mower into cutting posi-   tion.   START   Cranks the engine for starting.   NOTE: Never leave the ignition switch in the RUN posi-   tion with the engine stopped–this drains the battery.   Hour Meter / Maintenance Reminder   The hour meter measures the number of hours the key   has been in the RUN position. The hour meter will flash   an initial oil change indicator at 5 hours, and a lubrication   reminder every 50 hours. These reminders display for   approximately two hours and will automatically reset   themselves.   For attachment transport lift, pull the large lift lever back   fully to lock the control in the attachment raised transport   position.   Parking Brake   Note: The hour meter will register the passage of time   when the key is in the RUN position, even if the engine is   not running. The hour meter has a self contained power   source so the total hours are always visible.   DISENGAGE   ENGAGE   Releases the parking brake.   Locks the parking brake.   Pull the parking brake lever back to engage the parking   brake. Move the lever fully forward to disengage the   parking brake. NOTE: To start the unit the parking brake   must be engaged.   PTO Switch   The PTO (Power Take-Off) switch engages and disen-   gages attachments that use the PTO. To engage the   PTO, pull UP on the switch. Push DOWN to disengage.   Note that the operator must be seated firmly in the rider   seat for the PTO to function.   Transmission Oil Fill   Transmission oil is added through the transmission oil   expansion chamber. It also serves as extra holding   capacity for oil as the transmission heats up and the oil   expands. See CHECK TRANSMISSION OIL LEVEL for   oil level check and fill procedures.   Transmission Release Valves   The transmission release valves deactivate the transmis-   sions so that the unit can be pushed by hand. See   PUSHING THE UNIT BY HAND for operational informa-   tion.   Seat Adjustment Lever   The seat can be adjusted forward and backward. Move   the adjustment lever towards the left, slide the seat to the   desired position, and release the lever.   7 Download from Www.Somanuals.com.

(Clear the area of objects,   people and animals before you begin.) Operate the unit   at mid-throttle during this practice session (ALWAYS   operate at full throttle when mowing), and turn slowly to   prevent tire slippage and damage to your lawn.   SECOND, to go forward   gradually push the levers   forward with your palms.   THIRD, to speed up   move the levers farther   forward. To slow down   smoothly, slowly move   the levers toward neutral.   We suggest you begin with the Smooth Travel procedure   to the right, and then advance through the forward,   reverse, and turning maneuvers.   You must release the parking brake prior to moving the   control levers inward.   Figure 3. Move Control   Levers Gradually   BASIC DRIVING   Forward Travel Practice   Reverse Travel Practice   Gradually move both ground speed control levers —   evenly FORWARD from neutral. Slow down and repeat.   LOOK DOWN & BEHIND, then gradually move both   ground speed control levers evenly BACK from neutral.   Slow down and repeat.   NOTE: Straight forward travel takes practice. If neces-   sary, top speed can be balance-adjusted — see the   Speed Balancing Adjustment in the Adjustments section   near the back of this manual.   NOTE: Practice backing up for several minutes before   attempting to do so near objects. The rider turns as   sharply in reverse as when going forward, and backing   up straight takes practice.   Forward   Travel   Reverse   Travel   Figure 4. Forward Travel   Figure 5. Reverse Travel   10   Download from Www.Somanuals.com. All Manuals Search And Download.   Operation   Practice Turning Around a Corner   Practice Turning In Place   While traveling forward allow one handle to gradually   return back toward neutral. Repeat several times.   To turn in place, “zero turn,” gradually move one ground   speed control lever forward from neutral and one lever   back from neutral simultaneously. Repeat several times.   NOTE: To prevent pivoting directly on the tire tread, it is   best to keep both wheels going at least slightly forward.   NOTE: Changing the amount each lever is pulled—for-   ward or back, changes the “pivot point” you turn on.   Turning   In-Place   Executing   Turns   Figure 6. Turning Around a Corner   Figure 7. Turning in Place   ADVANCED DRIVING   Executing an End-Of-Row Zero   Turn   Your zero turn rider’s unique ability to turn in   place allows you to turn around at the end of   a cutting row rather than having to stop and Y-   turn before starting a new row.   For example, to execute a right end-of row   zero turn:   1. Slow down at the end of the row.   2. Move the LEFT ground speed control   lever forward slightly while moving the   RIGHT ground speed control lever back to   center and then slightly back from center.   3. Begin mowing forward again.   This technique turns the rider RIGHT and   slightly overlaps the row just cut —eliminating   the need to back up and re-cut missed grass.   As you become more familiar and experi-   enced with operating the zero turn rider, you   will learn more maneuvers that will make your   mowing time easier and more enjoyable.   Remember, the more you practice, the bet-   ter your control of the rider will be!   Figure 8. Executing an End-Of-Row Turn   11   Download from Www.Somanuals.com.
