SAFETY RULES

Safe Operation Practices for Ride-On Mowers

DANGER: THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROW ING OBJECTS. FAILURE TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH.

• Do not operate machine without the entire grass catcher,

WARNING: In order to prevent ac ci den tal starting when setting up, trans port ing, ad just ing or making repairs, al ways dis con nect spark plug wire and place wire where it can not contact spark plug.

WARNING: Do not coast down a hill in neutral, you may lose control of the tractor.

WARNING: Tow only the attachments that are rec om mend ed by and comply with spec i fi ca tions of the man u fac tur er of your tractor. Use common sense when towing. Operate only at the low est possible speed when on a slope. Too heavy of a load, while on a slope, is dan ger ous. Tires can lose trac tion with the ground and cause you to lose control of your tractor.

WARNING

Engine exhaust, some of its con stit u ents, and cer tain vehicle com po nents contain or emit chem i cals known to the State of Cal i for nia to cause can cer and birth de fects or oth er re pro duc tive harm.

discharge guard, or other safety devices in place and working.

• Slow down before turning.

• Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine, and remove keys before dismounting.

• Disengage blades 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.

• Operate machine only in daylight or good artificial light.

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

• Watch for traffic when operating near or crossing road ways.

• Use extra care when loading or unloading the machine into a trailer or truck.

• Always wear eye protection when operating machine.

• Data indicates that operators, age 60 years and above, are involved in a large percentage of riding mower-related injuries. These operators should evaluate their ability to operate the riding mower safely enough to protect them selves and others from serious injury.

• Follow the manufacturer's recommendation for wheel weights or counterweights.

• Keep machine free of grass , leaves or other debris build-up which can touch hot exhaust / engine parts and burn. Do not allow the mower deck to plow leaves or other debris which can cause build-up to occur. Clean any oil or fuel spillage before operating or storing the machine. Allow machine to cool before storage.

WARNING

Battery posts, terminals and related ac ces so ries contain lead and lead compounds, chem i cals known to the State of Cal i for nia to cause can cer and birth defects or oth er re pro duc tive harm. Wash hands after handling.

I. GENERAL OPERATION

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

• Do not put hands or feet near rotating parts or under the machine. Keep clear of the discharge opening at all times.

• Only allow responsible adults, who are familiar with the in struc tions, to operate the machine.

• Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blades.

• Be sure the area is clear of bystanders before operating. Stop machine if anyone enters the area.

• Never carry passengers.

• Do not mow in reverse unless absolutely necessary. Always look down and behind before and while back ing.

• Never direct discharged material toward anyone. Avoid discharging material against a wall or obstruction. Material may ricochet back toward the operator. Stop the blades when crossing gravel surfaces.

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. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.

• Mow up and down slopes, not across.

• Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

• Choose a low ground speed so that you will not have to stop or shift while on the slope.

• Do not mow on wet grass. Tires may lose traction.

Always keep the machine in gear when going down

slopes. Do not shift to neutral and coast downhill.

• Avoid starting, stopping, or turning on a slope. If the tires lose traction, disengage the blades and proceed slowly straight down the slope.

• Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction, which could cause the machine to roll over.

• Use extra care while operating machine with grass catchers or other at tach ments; they can affect the stability of the machine. Do no use on steep slopes.

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

• Do not mow near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel is over the edge or if the edge caves in.

SAFETY RULES

Safe Operation Practices for Ride-On Mowers

III. CHILDREN

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the ma chine and the mowing activity. Never assume that children will remain where you last saw them.

• Keep children out of the mowing area and in the watchful care of a responsible adult other than the operator.

• Be alert and turn machine off if a child enters the area.

• Before and while backing, look behind and down for small children.

• Never carry children, even with the blades shut off. They may fall off and be seriously injured or interfere with safe machine 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.

• Never allow children to operate the machine.

• Use extra care when approaching blind corners, shrubs, trees, or other objects that may block your view of a child.

IV. TOWING

• Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point.

• Follow the manufacturer's recommendation for weight limits for towed equipment and towing on slopes.

• Never allow children or others in or on towed equipment.

• On slopes, the weight of the towed equipment may cause loss of traction and loss of control.

• Travel slowly and allow extra distance to stop.

V. SAFE HANDLING OF GASOLINE

To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.

• Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

• Use only approved gasoline container.

• Never remove gas cap or add fuel with the engine running. Allow engine to cool before refueling.

• Never fuel the machine indoors.

• Never store the machine or fuel container where there is an open flame, spark, or pilot light such as on a water heater or other appliances.

• Never fill containers inside a vehicle or on a truck or trailer bed with plastic liner. Always place containers on the ground away from your vehicle when filling.

• Remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle.

• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.

• If fuel is spilled on clothing, change clothing immediately.

• Never overfill fuel tank. Replace gas cap and tighten securely.

GENERAL

• Never operate machine in a closed area.

• Keep all nuts and bolts tight to be sure the equipment is in safe working condition.

• Never tamper with safety devices. Check their proper operation regularly.

• Keep machine free of grass, leaves, or other debris build-up. Clean oil or fuel spillage and remove any fuelsoaked debris. Allow machine to cool before storing.

• If you strike a foreign object, stop and inspect the machine. Repair, if necessary, before restarting.

• Never make any adjustments or repairs with the engine run ning.

• Check grass catcher components and the discharge guard frequently and replace with manufacturer's recommended parts, when necessary.

• Mower blades are sharp. Wrap the blade or wear gloves, and use extra caution when servicing them.

• Check brake operation frequently. Adjust and service as required.

• Maintain or replace safety and instruction labels, as necessary.

• Be sure the area is clear of bystanders before operating. Stop machine if anyone enters the area.

• Never carry passengers.

• Do not mow in reverse unless absolutely necessary. Al ways look down and behind before and while backing.

• Keep children out of the mowing area and in the watchful care of a responsible adult other than the operator.

• Be alert and turn machine off if a child enters the area.

• Before and while backing, look behind and down for small children.

• Mow up and down slopes (15° Max), not across.

• Choose a low ground speed so that you will not have to stop or shift while on the slope.

• Avoid starting, stopping, or turning on a slope. If the tires lose traction, disengage the blades and proceed slowly straight down the slope.

• If machine stops while going uphill, disengage blades, shift into reverse and back down slowly.

• Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.

TO ADJUST MOWER CUTTING HEIGHT (See Fig. 11)

The position of the attachment lift lever (A) determines the cutting height.

• Repeat for opposite side installing gauge wheel in same adjustment hole.

Fig. 12

TO OPERATE MOWER

Your tractor is equipped with an operator presence sensing switch. Any attempt by the operator to leave the seat with the engine running and the attachment clutch engaged will shut off the engine. You must remain fully and centrally positioned in the seat to prevent the engine from hesitating or cutting off when operating your equipment on rough, rolling terrain or hills.

• Select desired height of cut (see "TO ADJUST MOWER CUTTING HEIGHT")

• Start mower blades by engaging at tach ment clutch control.

Fig. 11

• Put attachment lift lever in desired cutting height slot.

The cutting height range is ap prox i mate ly 1" to 4". The heights are measured from the ground to the blade tip with the engine not running. These heights are approximate and may vary depending upon soil conditions, height of grass and types of grass being mowed.

• The average lawn should be cut to approximately 2-1/2 inches during the cool season and to over 3 inches during 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 de sired height.

TO ADJUST GAUGE WHEELS (See Fig. 12)

Gauge wheels are properly adjusted when they are slightly off the ground when mower is at the desired cutting height in operating position. Gauge wheels then keep the deck in proper position to help prevent scalping in most terrain conditions.

NOTE:Adjust gauge wheels with tractor on a flat level surface.

• Adjust mower to desired cutting height (See “TO AD JUST MOWER CUT TING HEIGHT” in the Operation sec tion of this manual).

• With mower in desired height of cut po si tion, gauge wheels should be assembled so they are slightly off the ground. In stall gauge wheel in appropriate hole as shown and tighten se cure ly.

TO STOP MOWER BLADES

• disengage at tach ment clutch con trol.

CAUTION: Do not operate the mower without either the en tire grass catcher, on mowers so equipped, or the deflector shield (S) in place (See Fig. 13).

Fig. 13

REVERSE OPERATION SYSTEM (ROS) (See Fig. 14)

Your tractor is equipped with a Reverse Operation System (ROS). Any attempt by the operator to travel in the reverse direction with the attachment clutch engaged will shut off the engine unless ignition key is placed in the ROS "ON" position.

OPERATION

WARNING: Backing up with the attachment clutch en-

gaged while mowing is strongly discouraged. Turning the ROS "ON", to allow reverse operation with the attachment clutch engaged, should only be done when the operator decides it is necessary to reposition the machine with the attachment engaged. Do not mow in reverse unless absolutely necessary.

USING THE REVERSE OPERATION SYSTEM Only use if you are certain no children or other bystanders

will enter the mowing area.

• Move motion control lever to neutral (N) position.

• With engine running, turn ignition key counterclockwise to ROS "ON" position.

• Look down and behind before and while backing.

• Slowly move motion control lever to reverse (R) po si tion to start movement.

• When use of the ROS is no longer needed, turn the ignition key clockwise to engine "ON" position.

TO OPERATE ON HILLS

CAUTION: Do not drive up or down hills with slopes greater than 15° and do not drive across any slope.

• Choose the slowest speed before starting up or down hills.

• Avoid stopping or changing speed on hills.

• If slowing is necessary, move throttle control lever to slower position.

• If stopping is absolutely necessary, push clutch/brake pedal quickly to brake position and engage parking brake.

• Move motion control lever to neutral position.

IMPORTANT: THE MOTION CONTROL LEVER DOES NOT RETURN TO NEUTRAL POSITION WHEN THE BRAKE PED AL IS DEPRESSED.

• To restart movement, slowly release parking brake and clutch/brake pedal.

• Slowly move motion control lever to slowest setting.

• Make all turns slowly.

TO TRANSPORT (See Figs. 15)

When pushing or towing your tractor, be sure to disengage transmission by placing freewheel control in free wheel ing po si tion. Free wheel control is located at the rear drawbar of tractor.

• Raise attachment lift to highest position with at tach ment lift control.

• Pull freewheel control out and into the slot and release so it is held in the disengaged position.

• Do not push or tow tractor at more than two (2) MPH.

• To reengage transmission, reverse above procedure.

NOTE: To protect hood from damage when transporting your tractor on a truck or a trailer, be sure hood is closed and secured to tractor. Use an appropriate means of tying hood to tractor (rope, cord, etc.).

TOWING CARTS AND OTHER AT TACH MENTS

Tow only the attachments that are recommended by and comply with specifications of the manufacturer of your tractor. Use common sense when towing. Too heavy of a load, while on a slope, is dangerous. Tires can lose traction with the ground and cause you to lose control of your tractor.

BEFORE STARTING THE ENGINE

CHECK ENGINE OIL LEVEL

The engine in your tractor has been shipped, from the factory, already filled with sum mer weight oil.

• Check engine oil with tractor on level ground.

• Remove oil fill cap/dipstick and wipe clean, reinsert the dipstick and screw cap tight, wait for a few seconds, remove and read oil level. If necessary, add oil until “FULL” mark on dipstick is reached. Do not overfill.

• For cold weather operation you should change oil for easier starting (See “OIL VISCOSITY CHART” in the Maintenance sec tion of this manual).

• To change engine oil, see the Maintenance section in this manual.

ADD GASOLINE

• Fill fuel tank to bottom of filler neck. Do not overfill. Use fresh, clean, regular un lead ed 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 quan ti ties that can be used within 30 days to assure fuel freshness.

CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame.

OPERATION

IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW

32°F (0°C), USE FRESH, CLEAN WINTER GRADE GAS O LINE TO HELP ENSURE GOOD COLD WEATHER START ING.

CAUTION: Alcohol blended fuels (called gas o hol or using ethanol or methanol) can attract moisture which leads to sep a ra tion and for ma tion 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 stor age of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next sea son. See Storage In struc tions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

TO START ENGINE (See Fig. X)

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 freewheel control is in the transmission en gaged position.

• Sit on seat in operating position, depress clutch/brake pedal and set parking brake.

• Place motion control lever in neutral position.

• Move attachment clutch to “DISENGAGED” position.

• Move throttle control to choke position.

NOTE: Before starting, read the warm and cold starting procedures below.

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

WARM WEATHER STARTING (50° F and above)

• When engine starts, move the throttle control to the fast position.

• The attachments 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.

COLD WEATHER STARTING (50° F and below)

• When engine starts, allow engine to run with the throttle control in the choke position until the engine runs roughly, then move throttle control to fast position. This may require an engine warm-up period from several seconds to several minutes, depending on the tem per a ture.

AUTOMATIC TRANSMISSION WARM UP

• Before driving the unit in cold weather, the trans mis sion should be warmed up as follows:

• Be sure the tractor is on level ground.

• Place the motion control lever in neutral. Re lease the parking brake and let the clutch/brake slowly return to operating position.

• Allow one minute for transmission to warm up. This can be done during the engine warm up period.

• The attachments can also be used during the engine warmup period after the transmission has been warmed up.

NOTE: If at a high altitude (above 3000 feet) or in cold temperatures (below 32 F) the carburetor fuel mixture may need to be adjusted for best engine performance. See “TO ADJUST CARBURETOR” in the Service and Adjustments section of this manual.

PURGE TRANSMISSION

CAUTION: Never engage or disengage freewheel lever while the engine is run ning.

To ensure proper operation and performance, it is rec om mend ed that the transmission be purged before operating tractor for the first time. This procedure will remove any trapped air inside the transmission which may have de vel oped during shipping of your tractor.

IMPORTANT: SHOULD YOUR TRANSMISSION RE QUIRE REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD BE PURGED AFTER REINSTALLATION BEFORE OPERATING THE TRACTOR.

1. Place tractor safely on a level surface - that is clear and open - with engine off and parking brake set.

2. Disengage transmission by placing freewheel control in freewheeling position (See “TO TRANSPORT” in this section of manual).

3. Sitting in the tractor seat, start engine. After the engine is running, move throttle control to slow position. With motion control lever in neutral po si tion, slowly disengage clutch/brake pedal.

CAUTION: At any time, during step 4, there may be movement of the drive wheels.

4. Move motion control lever to full forward position and hold for five (5) seconds. Move lever to full reverse position and hold for five (5) seconds. Repeat this procedure three (3) times.

5. Move motion control lever to neutral position. Shut- off engine and set parking brake.

6. Engage transmission by placing freewheel control in engaged position (See “TO TRANSPORT” in this sec tion of manual).

7. Sitting in the tractor seat, start engine. After the engine is running, move throttle control to half (1/2) speed. With motion control lever in neutral position, slowly disengage clutch/brake pedal.

8. Slowly move motion control lever forward, after the tractor moves approximately five (5) feet, slowly move motion control lever to reverse position. After the tractor moves approximately five (5) feet return the motion control lever to the neutral position. Repeat this procedure with the motion control lever three (3) times.

Your transmission is now purged and now ready for normal op er a tion.

OPERATION

MOWING TIPS

• Mower should be properly leveled for best mowing per for mance. See "TO LEVEL MOWER HOUSING" in the Service and Adjustments section of this manual.

• The left hand side of mower should be used for trim ming.

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

• When mowing large areas, start by turning to the right so that clippings will discharge away from shrubs, fences, drive ways, etc. After one or two rounds, mow in the opposite direction making left hand turns until finished (See Fig. 16).

Fig. 16

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

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

• Always operate engine at full throttle when mow- ing to assure better mowing performance and proper dis charge of ma te ri al. Regulate ground speed by se lect ing a low enough gear to give the mower cutting per for mance 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.
