OPERATOR SAFETY Operator Safety Operating Safety Congratulations on purchasing a superior-quality piece of lawn and garden equipment. Our products are designed and manufactured to meet or exceed all industry standards for safety. Do not operate this machine unless you have been trained. Reading and understanding this operator’s manual is a way to train yourself. Power equipment is only as safe as the operator.
OPERATOR SAFETY Slope Operation Operation on slopes can be dangerous. Using the unit on a slope that is too steep where you do not have adequate wheel traction (and control) can cause sliding, loss of steering, control, and possible rollover. You should not operate on a slope greater than a 5.4 foot rise over a 20 foot length (15 degrees). Always mow across slopes, not up and down (to maintain traction on the wheels) and avoid sudden turns or rapid speed changes.
OPERATOR SAFETY Roll Bar Use Keep the roll bar in position and fasten the seat belt. Do not jump off if the mower tips (it is safer to be secured by the seat belt.) N ep o ro t fo du r ct io n NEVER remove the roll bar. Retaining Walls, Drop-offs, and Water R Retaining walls and drop-offs around steps and water are a common hazard. Give yourself a minimum of two mower widths of clearance around these hazards and hand-trim with a walk behind mower or string trimmer.
OPERATOR SAFETY Fuel and Maintenance Always disengage all drives, shutoff the engine, and remove the key before doing any cleaning, refueling, or servicing. Gasoline and its vapors are extremely flammable. Do not smoke while operating or refueling. Do not add fuel while engine is hot or running. Allow engine to cool for at least 3 minutes prior to adding fuel. Do not add fuel indoors, in an enclosed trailer, garage, or any other enclosed area that is not well ventilated.
OPERATOR SAFETY Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment. This mowing deck is capable of amputating hands and feet and throwing objects. The triangle in text signifies important cautions or warnings which must be followed. General Operation 19. Follow the manufacturer’s recommendations for wheel weights or counterweights. 20.
OPERATOR SAFETY Slope Operation Towed Equipment (Ride-On Units) 1. Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point. 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 equipment. 4. On slopes, the weight of the towed equipment may cause loss of traction and loss of control. 5.
OPERATOR SAFETY Service and Maintenance N ep o ro t fo du r ct io n Safe Handling of Gasoline 1. 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.

Control Functions N ep o ro t fo du r ct io n FEATURES AND CONTROLS The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing require the combined use of several controls applied in specific sequences. To learn what combination and sequence of controls to use for various tasks see the OPERATION section. R Deck Lift Pedal, Cutting Height Adjustment Pin & Deck Lift Lock Lever These control the cutting height of the mower deck.
FEATURES AND CONTROLS Ignition Switch Seat Adjustment Lever The ignition switch starts and stops the engine, it has three positions: OFF Stops the engine and shuts off the electrical system. RUN Allows the engine to run and powers the electrical system. The seat can be adjusted forward and back. Move the lever towards the left, position the seat as desired, and release the lever to lock the seat in position. Fuel Tank Cap To remove the cap, turn counterclockwise.
OPERATION Operation Checks Before Starting General Operating Safety Before first time operation: • Be sure to read all information in the Safety and Operation sections before attempting to operate this tractor and mower. • Become familiar with all of the controls and how to stop the unit. • Drive in an open area without mowing to become accustomed to the unit. • Check that crankcase is filled to full mark on dipstick (B, Figure 1).
OPERATION Check Tire Pressures Tire pressure should be checked periodically, and maintained at the levels shown in the chart. Note that these pressures may differ slightly from the “Max Inflation” stamped on the side-wall of the tires. The pressures shown provide proper traction, improve cut quality, and extend tire life. Tire Serial Number Pressure psi bar Front 2013129510 & Below 40 2,76 Front 2013129511 & Above 25 1,72 Rear All 15 1,03 Figure 2.
OPERATION Mowing Height Adjustment The cutting height adjustment pin (A, Figure 5) controls the mower cutting height. The cutting height is adjustable between 1-3/4” (4,4 cm) and 4-1/2” (11,4 cm) in 1/4” (0,64 cm) increments. 1. Depress the deck lift foot pedal (B) until it locks into the 4-1/2” (11,4 cm) position. 2. Place the cutting height adjustment pin in the desired cutting height. 3. Depress the deck lift foot pedal then push the lock lever (C) towards the right to release the lock. 4.
OPERATION WARNING Read the Operator’s Manual before attempting to operate the machine. • If you do not understand how a specific control functions, or have not yet thoroughly read the FEATURES and CONTROLS section, do so now. • Do NOT attempt to operate the tractor without first becoming familiar with the location and function of ALL controls. Stopping the Rider 1.
OPERATION Zero-Turn Driving Practice The lever controls of the Zero Turn rider are responsive, and learning to gain a smooth and efficient control of the rider’s forward, reverse, and turning movements will take some practice. Spending some time going through the maneuvers shown and becoming familiar with how the unit accelerates, travels, and steers — before you begin mowing —is absolutely essential to getting the most out of the Zero Turn rider.
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.
OPERATION Storage Before you store your unit for the off-season, read the Maintenance and Storage instructions in the Safety Rules section, then perform the following steps: WARNING Fuel and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death. • Never store the unit, with gasoline in the engine or fuel tank, in a heated shelter or in enclosed, poorly ventilated enclosures.
OPERATION The amount of grass you are able to cut in one pass is also effected by the type of mowing system you are using (for example, broadcasting with side discharge decks can process a much larger volume of grass than mulching does). Tall Grass Requires Incremental Cutting For extremely tall grass, set the cutting height at maximum for the first pass, and then reset it to the desired height and mow a second or third time. Don’t cover the grass surface with a heavy layer of clippings.
OPERATION Proper Mulching Attaching a Trailer Mulching consists of a mower deck which cuts and recuts clippings into tiny particles and which then blows them down INTO the lawn. These tiny particles decompose rapidly into by-products your lawn can use. UNDER PROPER CONDITIONS, your mulching mower will virtually eliminate noticeable clippings on the lawn surface. The maximum weight of a towed trailer should be less than 200 lbs (91kg).
REGULAR MAINTENANCE Regular Maintenance Maintenance Schedule The following schedule should be followed for normal care of your rider and mower. You will need to keep a record of your operating time. Determining operating time is easily accomplished by observing the elapsed time recorded by the hour meter.
REGULAR MAINTENANCE Checking / Adding Fuel WARNING To add fuel: 1. Stop the engine and allow to cool for at least 3 minutes. 2. Remove the fuel cap (see Figure 1). 3. Fill the tank to the bottom of the filler neck. This will allow for fuel expansion. NOTE: Do not overfill. Refer to your engine manual for specific fuel recommendations. 4. Install and hand tighten the fuel cap. Fuel Filter The fuel filter is located in the fuel line between fuel tank and carburetor, near the fuel pump.
REGULAR MAINTENANCE Check Hydraulic Oil Level 1. Before removing the reservoir cap, make sure the area around the reservoir cap and fill neck of the reservoir is free of dust, dirt, or other debris. 2. Unscrew the reservoir cap (B, Figure 19). 3. Look down the filler neck of the hydraulic oil reservoir (A) and observe the oil level. When cold, the oil level should be approximately 4” (10 cm) below top of the filler neck. 4. If necessary, add SAE 20W-50 motor oil. DO NOT use synthetic oils. 5.
REGULAR MAINTENANCE Lubrication Lubricate the unit at the locations shown in Figures 21 through 25 as well as the following lubrication points. Grease: • front caster wheel axles & yokes • deck lift pivot blocks • mower deck spindles • mower deck idler arm Use grease fittings when present. Disassemble parts to apply grease to moving parts when grease fittings are not installed. Figure 21. Deck Lubrication Not all greases are compatible. Use automotive-type lithium grease.
