SAFETY RULES

Safe Operation Practices for Ride-On Mowers

IMPORTANT: 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.

I. GENERAL OPERATION

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

• 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 blade.

• Be sure the area is clear of other people before mow ing. 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.

• Be aware of the mower discharge direction and do not point it at anyone. Do not operate the mower without either the entire grass catcher or the guard in place.

• Slow down before turning.

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

• Turn off blades when not mowing.

• Stop engine before removing grass catcher or un clog ging chute.

• Mow only in daylight or good artiﬁ cial light.

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

• Watch for trafﬁ c when operating near or crossing road ways.

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

• 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.

• 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.

II. SLOPE OPERATION

Slopes are a major factor related to loss-of-control and tipover 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.

DO:

• Mow up and down slopes, not across.

• Remove obstacles such as rocks, tree limbs, etc.

• Watch for holes, ruts, or bumps. Uneven terrain could overturn the machine.

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

• Follow the manufacturer’s recommendations for wheel weights or counterweights to improve stability.

• Use extra care with grass catchers or other at tach ments. These can change the stability of the machine.

• Keep all movement on the slopes Do not make sudden changes in speed or direction.

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

Tall grass can hide obstacles.

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. children will remain where you last saw them.

• Keep children out of the mowing area and under the watchful care of another responsible adult.

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

• Before and when backing, look behind and small children.

• Never carry children. They may fall off and be seriously injured or interfere with safe machine operation.

• Never allow children to operate the machine.

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

IV. SERVICE

• Use extra care in handling gasoline and other fuels. They are ﬂ ammable and vapors are explosive.

- Use only an approved container.

- Never remove gas cap or add fuel with the engine

running. Allow engine to cool before refueling. Do not smoke.

- Never refuel the machine indoors.

- Never store the machine or fuel container inside where

there is an open ﬂ ame, such as a water heater.

• Never run a machine inside a closed area.

• Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition.

• Never tamper with safety devices. Check their proper op er a tion regularly.

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

• Stop and inspect the equipment if you strike an object. Repair, if necessary, before restarting.

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

• Grass catcher components are subject to wear, dam age, and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check com po nents and replace with manufacturer's rec om mend ed parts, when nec es sary.

• Mower blades are sharp and can cut. Wrap the blade(s)

or wear gloves, and use extra caution when servicing them.

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

SAFETY RULES

Safe Operation Practices for Ride-On Mowers

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

• Never carry passengers or children even with the blades off.

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

• Never carry children. They may fall off and be seriously injured or interfere with safe machine operation.

• Keep children out of the mowing area and under the watchful care of another responsible adult.

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

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

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

• Remove obstacles such as rocks, tree limbs, etc.

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

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

• Avoid starting or stopping on a slope. If 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 tur n on slopes unless necessary, and then, tur n slowly and gradually downhill, if possible.

WARNING: In order to prevent ac ci - den tal start ing 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 pos si ble speed when on a slope. Too heavy of a load, while on a slope, is dan ger ous.

) to lower cutting

height.

The cutting height range is approximately 1-1/2" to 4". The heights are measured from the ground to the blade tip with the engine not running. These heights are ap proxi mate 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 ﬁ rst cut relatively high; the second to desired height.

TO ADJUST GAUGE WHEELS (See Fig. 11)

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.

CAUTION: Do not operate the mower without either the en tire grass catcher, on mowers so equipped, or the deﬂ ector shield in place.

TO OPERATE ON HILLS

WARNING: 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 (N) position.

IMPORTANT: THE MOTION CONTROL LEVER DOES NOT RETURN TO NEUTRAL (N) POSITION WHEN THE CLUTCH/ 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. 9 and 13)

When push ing or tow ing your trac tor, be sure to disengage transmission by placing freewheel control in free wheel ing po si tion. Free wheel control is located under the seat.

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

• Raise seat and pull freewheel control up and back 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.).

OPERATION

TOWING CARTS AND OTHER AT TACH MENTS

Tow only the attachments that are recommended by and comply with speciﬁ cations 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 ﬁ lled with sum mer weight oil.

• Check engine oil with tractor on level ground.

• Pull up and remove oil ﬁ ll cap/dipstick; wipe oil off. Reinsert the dipstick into the tube and push down ﬁ rmly into place. Remove and read oil level. If necessary, add oil until “FULL” mark on dipstick is reached. Do not overﬁ ll.

• 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 ﬁ ller neck. Do not overﬁ ll. 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 ﬂ ame.

IMPORTANT: WHEN OPERATING IN TEMPERATURES

BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE GAS O LINE TO HELP INSURE GOOD COLD WEATHER START ING.

CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to sep a ra tion and for ma tion of acids during stor age. 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 season. See Storage In struc tions for ad di tion al information. Never use engine or car bu re tor cleaner products in the fuel tank or permanent damage may occur.

TO START ENGINE (See Fig. 9)

When starting the engine for the ﬁ rst 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 (N) 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 ﬁ fteen 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 warm-up 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.
