Safety Precautions Safe Operation Practices For Ride-On Mowers Do not operate the machine while under the influence of medication, alcohol or drugs. 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. Watch for traffic when operating near or crossing roadways or drives.
Safety Precautions (Continued) 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. Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.
Safety Precautions (Continued) Grass catcher components are subject to wear, damage, and deterioration, which could expose moving par ts or allow objects to be thrown. Frequently check components and replace, with manufacturer’s recommended parts, when necessary. Check brake operation frequently. Adjust and service as required. Refer to Storage Section of this owners manual if unit is to be stored for extended period. Mower blades are sharp and can cut.

Operation Hood Safety Interlock System To open the hood, push the hood latch located inside the center of grille to the left. To prevent possible damage, do not slam the hood to close it, use a firm downward push at the center of the hood to ensure that the latch engages. Tractor should not be driven unless the hood is fully closed and latched. Engine must shut off if the operator attempts to leave the seat with the transmission engaged, parking brake disengaged or PTO engaged.
Operation (Continued) Throttle/Choke • • applying load. IMPORTANT: Run engine at 1/2 of (FAST) engine speed for at least five minutes in below freezing temperatures to prevent internal damage to engine and transaxle. FAST ENGINE SLOW CHOKE SPEED Throttle/Choke lever controls engine speed (to increase, push up-to decrease, pull down) and activates choke (push lever up and to right past offset). On the 16 HP B & S twin model, the throttle and choke are separate controls.
Operation (Continued) Parking Brake CAUTION: Before leaving operators position, engage parking brake and lock. 4 3 • 2 Parking Brake is provided to prevent tractor from rolling when parked or left unattended. 1 N Speed Selector USE CLUTCH WHEN SHIFTING • To engage parking brake, shift into neutral, depress clutch/brake pedal and pull parking brake knob out, then release clutch/brake pedal. Parking brake lock is disengaged by depressing clutch/brake pedal.
Operation (Continued) Electric PTO 1 DANGER: Failure of interlock, together with improper operation of unit, could result in severe personal injury. Engine must not start unless Implement Power is disengaged (Off). 2 WARNING: Keep hands, feet, hair and clothing away from rotating parts. • To engage Implement Power, lift switch up to (On) position to start attachment rotation. To disengage, push switch down (Off) position to automatically apply blade brake and stop attachment rotation.
Operation (Continued) NOTE: This product is equipped with an internal combustion engine. DO NOT use on or near any unimproved, forest covered or brush covered land unless the exhaust system is equipped with a spark arrester meeting applicable, local, state or federal laws. 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.
Operation (Continued) • • 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. 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.
Lubrication and Maintenance RECOMMENDED SAE VISCOSITY GRADES Briggs Engines 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. 10W30 30 ** 5W30 10W30 WARNING: ACCIDENTAL ENGINE START UP can cause death or serious injury.
Lubrication and Maintenance (Continued) Changing Oil 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. IMPORTANT: Change oil after first 2 hours of operation. Thereafter change oil every 25 hours of operation (more often in dusty, dirty conditions).
Lubrication and Maintenance (Continued) Fuel Filter 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. 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. To clean, remove spark plug from engine, scrape or wire brush, and wash with a commercial solvent. DO NOT blast clean.
