Safety Precautions

Safe Operation Practices For Ride-On Mowers

• This cutting machine is capable of amputating hands and feet and throwing objects.
• Failure to observe the following safety instructions could result in serious injury or death. Your complete and unimpaired attention is required at all times.

General Operation

• Read, understand, and follow all instructions in this owners manual, the engine manual and on the machine before starting.
• Only allow responsible adults, who are familiar with the instructions, 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 and pets before mowing. 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 backing.
• 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 inplace.
• Slow down before turning to prevent tipping or loss of control.
• Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine, and remove keys to prevent unauthorized use before dismounting.
• Turn off blades when not mowing.
• Disengage mower clutch, stop engine, remove key and wait for moving parts to stop before leaving operators position for any reason such as removing grass catcher or unclogging chute.
• Mow only in daylight or good artificial light.
• Do not operate the machine while under the influence of medication, alcohol or drugs.
• Watch for traffic when operating near or crossing roadways or drives.
• Use extra care when loading or unloading the machine into a trailer or truck.
• Use only attachments or accessories designed for your unit. See your Ariens Dealer.
• Wear sturdy footwear. Do not operate riding mower barefoot or when wearing open sandals or canvas shoes. Do not wear loose clothing that may get caught in rotating parts of unit. Wear safety goggles or safety glasses with side shields when operating mower.

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.

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. 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.
• Follow the manufacturer’s recommendations for wheel weights or counterweights to improve stability.
• Use extra care with grass catchers or other attachments. These can change the stability of the machine. Use only approved hitch points.
• Limit loads to those you can safety control.
• Keep all movement on the slopes slow and gradual.
• Do not make sudden changes in speed or direction.
• Avoid starting or stopping on a slope. If tires lose traction, disengage mower clutch and proceed slowly straight down the slope. If you must stop when going up the slope and can not safely back down: for gear drive models, depress clutch/brake pedal, disengage mower clutch, place travel speed selector in first gear (low speed) and slowly release the clutch/ brake pedal.
• For hydro models depress clutch/brake pedal only if necessary, disengage mower clutch, slowly release clutch brake pedal and slowly engage the forward pedal.

Do Not

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

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.
• 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.
• Never carry children, even when attachments are off.
• 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.

Service

• Do not change engine governor setting or over speed the engine.
• Replace damaged or worn out muffler immediately.
• Continued use could result in fire or explosion.
• Use extra care in handling gasoline and other fuels. They are flammable 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. Wipe off any spilled gasoline and allow vapors to dissipate before starting engine.
  • Replace fuel tank cap and container cap securely.
  • Never refuel the machine indoors.
  • Never store the machine or fuel container inside where there is an open flame, such as in a water heater.
• Never run a machine inside a closed area. Exhaust fumes contain carbon monoxide an odorless and deadly gas.
• Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition.
• Never tamper with safety devices. Check their proper operation regularly. See page 7 for safety interlock check.
• Keep machine free of grass, leaves, or other debris build-up. Clean up oil or fuel spillage. Allow machine to cool before storing.
• Stop and inspect the equipment if you strike an object. Repair any damage before restarting.
• Never make adjustments or repairs with the engine running or when engine and exhaust parts are hot from operation.
• Grass catcher components are subject to wear, damage, and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace, with manufacturer’s recommended parts, when necessary.
• 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.

A spark arrester, if used, must be maintained in effective working order by the operator. See your Ariens Dealer or engine manufacturer’s service center.

Stopping (Hydro)

• To stop, disengage cruise and/or remove foot from pedal, disengage Implement Power (Off), lower attachment, and engage Parking Brake.
• Lower engine speed to idle, and allow engine to idle for a few minutes so that engine parts can cool evenly before shutting engine off.
• Turn Ignition Key counterclockwise to stop engine and remove key.

Operating Tips

• The following tips will help you to mow safely, achieve maximum performance from your yard tractor and maintain the appearance of your lawn.
• Be sure your mower blade(s) is/are sharp. A dull blade will tear grass blades. (This usually results in a white cast over a freshly cut lawn. Later, tips of grass blades will turn brown.)
• Proper leveling and pitch of rotary mower pan is essential to obtain a smooth even lawn mowing operation. Reverse or inadequate pitch makes blade cut grass twice, resulting in frazzled fresh cut lawn. Two much pitch causes through type uneven cut. Improper leveling results in step type uneven cut. (Refer to Adjustments Section for Level and Pitch instructions.)
• A new lawn has much softer blades of grass and has a higher moisture content. It is important for this type of lawn to be cut with sharp blades.
• Cutting height will vary with different types of grass, climate, and individual preference.
• When first using your rotary mower, cut grass a little longer than you did with narrower cutting units until you are sure that a greater cutting width will not cause scalping due to irregularities in lawn.
• Generally, grass should be cut about 1-1/2” long in spring, and not less than 2” long in hot summer weather.
• If grass is high, or if it contains a high degree of moisture, cut it first with mower pan set high and then cut it with mower pan set lower. This gives better distribution of clippings and provides a clean second cut.
• Height of cut should not be set too low on thick, lush lawns. Such grass, if cut too short, may die. This also applies to springy, heavy growth lawns. If blade is set too low, mower pan will drag on grass and restrict air flow thus reducing discharge of grass clippings.

WARNING: NEVER attempt to clear rotary mower pan or discharge while engine is running. Disengage Implement Power (Off), stop engine, remove key, wait for moving parts to stop before attempting to clean away any obstruction.

• Grass should be cut when it is dry; not when it is wet from dew, rain or from watering. Wet grass tends to pack inside mower pan and will not discharge, mulch or bag properly, especially if height of cut is set too low.

CAUTION: Stay alert for holes, rocks, roots and hidden hazards in area of operation. Exercise extreme caution when operating on or crossing gravel drives, walks or roads. Stay alert for traffic.

• To insure most complete and even cut, overlap each swath.
• Plan your cutting so that you always trim with the left side of mower pan.
• Following the same pattern each time you mow your lawn can develop ridges at right angles to direction of mowing. By changing direction of mowing (when possible) you can prevent this.
• Turn clockwise (right turn) when beginning to mow large, open areas. This discharges clippings away from borderline objects (sidewalks, driveways, fences, etc.). After making a clockwise pass, mow in a counterclockwise (left turn) direction. This discharges clippings evenly over cut grass. Continuous clockwise mowing will cause a build up of clippings, preventing a uniform cut.
• Proper adjustment of anti-scalp wheels is important for obtaining smoothest appearing cut especially over uneven terrain. Refer to Adjustments Section for recommended positions.
• Slow down when making turns. Short, fast turns can cause scuffing (outside front tire slides and pulls out grass), step type cutting or some grass may not be cut.
• When mowing, regulate forward travel speed with Speed Selector and always operate engine at full throttle. This maintains proper blade speed and air flow to facilitate discharging of clippings. Mowing with a lower throttle setting causes blade to tear grass, resulting in poor lawn appearance.
• A good fertilization program and frequent watering will help keep your lawn weed free and green all year long. Due to variations in climate, soil and grass varieties, contact your local garden supply dealer, park or golf course superintendent, or county agent to obtain specific information pertaining to your area.

NOTE: Be sure to clean mower pan after each use. Do not allow grass clumps or a coating of grass and debris to collect inside of mower pan. Avoid operation over bare ground intermittent with grass cutting as this causes dirt and grass to collect and cake under pan surface.

Lubrication and Maintenance

Your dealer will provide any service which may be required to keep tractor operating at peak efficiency. Should engine or transaxle service be required, it can be obtained from your dealer or an authorized engine or transaxle manufacturer’s service center.

WARNING: ACCIDENTAL ENGINE START UP can cause death or serious injury. ALWAYS stop engine, remove key, wait for moving parts to stop and remove wire from spark plug before adjusting or servicing.

CAUTION: DO NOT touch engine or tractor parts which are hot from operation. Allow such parts to cool before servicing unit.

1. Oil Fill and Dipstick
2. Air Filter
3. Starter Motor
4. Oil Drain

Service Position

• Place unit on a flat level surface. ALWAYS stop engine and disengage clutches. Assure unit is secure and will not tip over. Strap and clamp onto lift if used.

Engine Oil

• Use a high quality oil classified for Service SF or SG.
• These oils keep engine cleaner and retard formation of gum and varnish deposits. DO NOT add anything to recommended oil.
• Refer to chart for recommended viscosity grades and chart from engine manufacturers instructions to use with temperature range anticipated before next oil change.

RECOMMENDED SAE VISCOSITY GRADES Briggs Engines

Kohler Engines

• Air cooled engines run hotter than automotive engines. Use of multi-viscosity oils (10W- 30, etc.) above 40°F (4°C) will result in high oil consumption. Check oil level more frequently if using these types of oils. Refer to engine manufacturers manual for recommended oil.
  ** SAE 30 oil, if used below 40°F (4°C), will result in hard starting and possible engine bore damage due to inadequate lubrication.

Checking Oil

The engine crankcase oil should be checked daily or every 5 hours of operation. To check oil, park tractor on a flat level surface, stop engine, raise hood and wipe all debris from around dipstick cap. Turn cap, remove dipstick from engine and wipe oil off dipstick. Insert dipstick into filler tube and turn slowly until cap bottoms firmly. Remove dipstick and observe oil level. If low, add clean fresh oil (of same type and viscosity as is in engine) to bring oil level to full (F) mark. Replace dipstick and tighten cap firmly.

IMPORTANT: DO NOT over fill. Level must not exceed full (F) mark. Oil level MUST be maintained in safe operating range on dipstick at all times or engine damage will result.

Changing Oil

IMPORTANT: Change oil after first 2 hours of operation. Thereafter change oil every 25 hours of operation (more often in dusty, dirty conditions). See chart for proper type and viscosity.

NOTE: Run engine just prior to changing oil. Oil will flow more freely and carry away more contamination when warm.

Drain engine crankcase by removing oil drain cap. After oil has drained, replace cap and lift hood. Remove oil fill cap and dipstick. Pouring slowly, fill crankcase with oil. (See specifications section for amount of oil). Check oil level with dipstick, making sure you replace dipstick and tighten cap firmly.

Air Cleaner

_ IMPORTANT: _Never run engine without complete air cleaner installed on engine.

Foam Filter

• Clean and reoil every three (3) months or every 25 operating hours. Clean and reoil daily if used in extremely dusty conditions.
• Wash in water and detergent solution and squeeze (don’t twist) until all dirt is removed. Rinse thoroughly in clear water. Wrap in a clean cloth and squeeze (don’t twist) until completely dry. Saturate with engine oil and squeeze (don’t twist) to distribute oil and remove excess oil.

Paper Filter

• Do not attempt to clean or oil filter. Replace once a year or every 100 operating hours, more often if used in extremely dusty conditions.
• Replacement filters are available at any Authorized Tecumseh Service Outlet.

Remove and Install Filter

• Remove wing nuts and cover. Slide Filter A off Filter B.
• Inspect filter(s) for discoloration or dirt accumulation.
• If either is present, service per preceding “Service Filter” instructions. Remove nuts and Filter B.

Discard Filter B and nuts (if service is necessary). Clean inside of cover and body thoroughly. Install new Filter B and new nuts. Tighten nuts finger tight and then turn one (1) more complete turn. Slide foam filter over paper filter. Install cover and wing nuts. Tighten wing nuts.

Oil Filter

• Oil filter should be changed at every other oil change.
• To change oil filter, drain engine crankcase and then remove old filter.
• Before installing replacement filter, apply a thin coating of oil on surface of rubber seal. Also, clean filter adapter gasket surface.
• Turn filter clockwise until rubber seal contacts filter adapter, then tighten filter an additional 2/3 to 3/4 turn.
• Fill engine crankcase with new oil of the proper type to “F” mark on dipstick.
• NOTE: Oil filter requires an additional 1/2 pint of oil.
• Start engine and check for oil leakage around filter and at drain plug.

Fuel Filter

WARNING: Gasoline is flammable and must be handled with care. DO NOT allow open flame, matches or smoking in area. Wipe up any spills. Use approved (RED) fuel container.

1. Fuel Filter

• Fuel filter should be replaced every season.

Engine Cooling

• The engine is air cooled. Air must circulate freely around engine from air intake screen, over cooling fins on cylinder head and block to prevent overheating.

CAUTION: Use non-flammable solvent to clean parts – DO NOT use gasoline.

Every 100 operating hours or yearly (more often if conditions require) remove blower housing and clean cooling fins. Also clean external surfaces of your engine of dust, dirt and oil deposits which can contribute to improper cooling.

IMPORTANT: DO NOT operate engine with blower housing removed. This will cause overheating and engine damage.

CAUTION: Periodically clean muffler and manifold areas to remove all grass, dirt and combustible debris. If engine muffler is equipped with spark arrester screen assembly, remove every 50 hours for cleaning and inspection. Replace if damaged.

Spark Plugs

• Spark plugs should be cleaned or replaced (if necessary) and gap reset to .030” every 100 hours of operation or yearly, whichever comes first.
• To clean, remove spark plug from engine, scrape or wire brush, and wash with a commercial solvent. DO NOT blast clean.

NOTE: Sparking can occur if wire terminal does not fit firmly on spark plug. Reform terminals if necessary.

Muffler

• Worn out mufflers are more than just a noise nuisance and should be replaced immediately. Continued use could result in fire or explosion.

Transaxle (Gear and Hydro)

• Unless there are indications of leakage, transaxle does not have to be checked for proper oil level. If leakage occurs, have leak repaired by your dealer.

Battery

WARNING: Batteries product explosive gases which can cause personal injury. DO NOT allow flames, sparks or any ignited object to come near battery. When charging or working near a battery, always shield your eyes and provide ventilation.

CAUTION: Keep batteries out of reach of children. Batteries contain sulfuric acid. Avoid contact with skin, eyes or clothing. In case of acid contact with skin, eyes or clothing, flush immediately with water for a minimum of 15 minutes. If acid is swallowed, drink large quantities of milk, egg or vegetable oil. Call a physician immediately.

WARNING: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

Every 25 hours or each week check electrolyte level of each cell by removing battery cover. The electrolyte level should be at level indicator. Use distilled watter to fill each cell if needed. Install battery cover after checking.

IMPORTANT: When distilled water is added to battery during freezing weather, battery must be charged to mix water with electrolyte, or water will remain at top and freeze.

Keep battery and its terminals clean, and inspect monthly to maintain best performance.

WARNING: DO NOT allow tools or other objects to come into contact with both terminals at same time. When removing battery from tractor, remove negative (-) cable first to reduce risk of sparks.

To clean terminals remove battery from tractor byremoving cables. Remove battery strap and lift battery out. Clean or service battery away from unit. Remove corrosion from battery terminals and cable connections with a wire brush, then wash with a weak baking soda solution. After cleaning, apply a thin coat of grease or petroleum jelly to terminals and cable ends to retard corrosion. Reinstall battery.

CAUTION: Connect positive (+) cable first, negative (-) cable last.

To charge battery remove battery from tractor, remove vents, and charge at a rate of 4 to 6 amps for 10 hours on a fully discharged battery. (Specific Gravity reading of 1260 plus or minus 5 points on all cells.)

IMPORTANT: DO NOT fast charge. Charging at a higher rate will damage or destroy battery.

WARNING: When charging battery, remove it from tractor and make certain that you connect positive (+) lead of charger to positive (+) terminal, and negative (-) lead to negative (-) terminal. Reverse connections can cause sparks and potential unsafe conditions.

Jump Starting

• Jump starting, battery charging or replacement is required when the starter motor will not crank the engine.

WARNING:  FROZEN BATTERIES CAN EXPLODE and result in death or serious injury. DO NOT charge a frozen battery. Let the battery thaw out before putting on a charger.

To jump start battery

• Ensure battery is not frozen. If the fluid is frozen, remove battery from unit and allow it to thaw before charging.
• The unit used for jump starting should have a 12 volt battery with at least 500 cold cranking amperes, and a negatively grounded system.

General Lubrication

IMPORTANT: Wipe each grease zerk fitting clean before and after lubrication. Keep grease and oil off belts to avoid slippage and deterioration.

NOTE: Apply Hi-Temp Grease or equivalent. Order P/N: 00036800 – three pack of 3 oz. cartridges or P/N 00036700 – ten pack of 14 oz. cartridges. Apply oil at all lubrication points.

• The steering system, front axle and wheels, brake/clutch shaft support and pivot points should be lubricated every 50 hours of operation, or every 3 months, whichever occurs first.
• Grease fittings are indicated below. Oil pivot points on brake, clutch and mower deck linkage as needed. Hydrostatic transaxles do not have grease fittings.

Rotary Mower Removal

• Place (2) supports approximately 1 1/2” high (the thickness of a 2” x 4”) under the right hand and left hand side of the mower deck.
• Lower the mower deck onto the supports thus relieving all the mower deck’s weight from the tractor’s lift system.
• Disconnect the mower rear hangers by pulling the hair pins out of the tractor mount lugs.
• Slide the mower deck forward just enough to remove the front pin and front lift arms from the tractor front hooks.
• Remove the mower height adjusters from the tractor lift lever hooks.

Tires

NOTE: Keep tires properly inflated at all times. For proper tire inflation when working under various conditions, refer to chart below. Use a low pressuretire gauge for accurate pressure readings.

Loading

Check tire pressure at least once a month. Over inflation may cause operator discomfort andexcessive tire tracks on lawns or soft surfaces, while under inflation causes short tire life.

NOTE: After checking and/or inflating, replace andtighten valve caps to prevent air loss.

Seat

Clean seat regularly, using a vinyl cleaner (not solvent). Extreme temperatures can damage seat when left unprotected against weather. If seat should tear, apply vinyl repair tape to protect damaged area.

Mower Blade

_ CAUTION: _Use sturdy gloves or padding to protect hands when working with mower blade.

• Regularly check mower blade(s) for wear (vanes if used) and that lock washer is fully compressed by nut (requires 50-60 ft. lbs. of torque on nuts).

WARNING: Stop engine, remove key, wait for moving parts to stop and remove wire from spark plug before attempting any maintenance procedures.

CAUTION: Wear of mower blade will cause structural weakness. DO NOT install new or replacement vanes on worn blades.

1. Cutting Blade
2. Square Corner
3. Air Lift Erosion
4. Air Lift

When blade needs sharpening, block blade to prevent rotation and remove nut, lock washer and blade from shaft. Sharpen both ends of blade at original angle (25 degrees), removing equal amounts of material from each end to maintain proper blade balance. New blades are balanced to within 1.3 inch ounces at factory. DO NOT grind around corner at tip of blade.

If cutting edge of blade cannot be sharpened to asquare corner to within 1/8 of an inch of its end, replace blade with Ariens replacement blade only. Blades are available through your dealer. Install blade and lock washer and tighten nut until lock washer is fully compressed (requires 50-60 ft. lbs. of torque on nuts).

NOTE: If mower is used under sandy soil conditions, replace blades when air lifts become eroded through at ends.

Always use recommended parts and accessories to ensure your machines peak performance.

Adjustments

Adjustments should be made by your dealer. Your dealer has the knowledge and tools to properly perform adjustments which may be required to keep your equipment operating at peak efficiency. Should you decide to make the following adjustments on your unit yourself. Call your dealer for answers to any questions that might arise.

WARNING: Lower attachment, engage parking brake, stop engine, remove key, wait for moving parts to stop before leaving operators position and attempting to make any adjustments.

Mower Pitch and Height

• Proper blade pitch is when blade tip (measured from surface is 1/8” to 1/4” lower at front of mower pan than when same tip is at rear of mower pan. To adjust pitch loosen flangelock nuts and slide adjusting tabs up or down to achieve proper pitch (Figure 20 & 22).
• Adjusting height adjuster hooks equally raises or lowers mower pan and changes cutting height. To adjust, loosen upper nuts on hanger hooks and turn lower nuts equally clockwise to lower or counterclockwise to raise rear of rotary mower. With mower attachment lift in highest position front blade height should measure 4” from ground level.
• Secure hanger hooks in position by securely tightening nuts.

Mower Attachment Lift

• Depress thumb pin and move attachment lift lever to rear for maximum cutting height (4”). Depress thumb pin and move attachment left lever to forward position for lowest cutting height (1”). Intermediate positions allow selection of cutting heights between these values.

Anti-Scalp Rollers (40” Mower Pan)

• Secure rollers in middle position for average lawn mowing. Use lowest roller position when mowing in higher cutting heights and rough terrain to guard against most scalping. Use highest roller position when cutting at lowest cutting height.
• For smoothest appearing cut when using frame suspended models with anti-scalp rollers, keep anti-scalp rollers adjusted to the minimum 1/2” above flat hard smooth surface after setting height of cut.

NOTE: The rollers are intended for anti-scalping, not for controlling cutting height.
