Safety Rules & Information 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.
Safety Rules & Information 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.
Safety Rules & Information Safety Retaining Walls, Drop-offs, and Water 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. Wheels dropping over retaining walls, edges, ditches, embankments, or into water can cause rollovers, which may result in serious injury, death, or drowning.
Safety Rules & Information GENERAL OPERATION 1. Read, understand, and follow all instructions in the manual and on the unit before starting. 2. Do not put hands or feet near rotating parts or under the machine. Keep clear of the discharge opening at all times. 3. Only allow responsible adults, who are familiar with the instructions, to operate the unit (local regulations can restrict operator age). 4. Clear the area of objects such as rocks, toys, wire, etc.
Safety Rules and Information Safety 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 operate on it. Control of a walk-behind or ride-on machine sliding on a slope will not be regained by the application of the brake.

Controls Features & Controls CONTROL FUNCTIONS 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. Ground Speed Control Levers These levers control the ground speed of the rider.
Features & Controls Hour Meter The hour meter measures the number of hours the key has been in the RUN position. Note: The hour meter will register the passage of time when the key is in the RUN position, even if the engine is not running. The hour meter has a self contained power source so the total hours are always visible. The PTO (Power Take-Off) switch engages and disengages attachments that use the PTO. To engage the PTO, pull UP on the switch. Push DOWN to disengage.
Operation 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 brake lever or set the parking brake. CHECKS BEFORE STARTING • Check that crankcase is filled to full mark on dipstick.
Operation WARNING If you do not understand how a specific control functions, or have not yet thoroughly read the FEATURES & CONTROLS section, do so now. Do NOT attempt to operate the tractor without first becoming familiar with the location and function of ALL controls. STARTING THE ENGINE 5. After warming the engine, ALWAYS operate the unit at FULL THROTTLE when mowing. In the event of an emergency the engine can be stopped by simply turning the ignition switch to STOP.
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 bring one handle gradually 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. Executing Turns Turning In-Place Operation Figure 6.

Operation C M Removal 1. Disengage the PTO, engage the parking brake, turn off the ignition, remove the key, and wait for all moving parts to stop. 2.
Operation MOWING Before mowing, set the cutting height as described in the Troubleshooting, Adjustments & Service section. 1. Engage the parking brake. Make sure the PTO switch is disengaged and the motion control lever is in the NEUTRAL position. 2. Start the engine (see STARTING THE ENGINE). 3. Set the throttle to FULL. 4. Engage the PTO by pulling up on the PTO switch. 5. Begin mowing. See Mowing Recommendations section for tips on mowing patterns and lawn care.
Operation When and How Often to Mow The time of day and condition of the grass greatly affect the results you’ll get when mowing. For the best results, follow these guidelines: 1. Mow when the grass is between three and five inches high. 2. Mow with sharp blades. Short clippings of grass one inch or shorter decompose more quickly than longer blades. Sharp mower blades cut grass cleanly and efficiently, preventing frayed edges which harm the grass. 3. Mow at time of day when the grass is cool and dry.
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 MAINTENANCE SCHEDULE & PROCEDURES 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 LUBRICATION Lubricate the unit at the following lubrication points shown in Figure 16. Grease: • front caster wheel axles • front caster yokes Oil: • control handle pivots • discharge chute hinge • roller straps (deck lift pivots) • mower deck idler arm pivot • mower deck arbors Use grease fittings when present. Disassemble parts to apply grease to moving parts when grease fittings are not installed.
Regular Maintenance SERVICING THE MOWER BLADES Removing the Mower Blade CAUTION Avoid injury! Mower blades are sharp. • Always wear gloves when handling mower blades or working near blades. 1. See Figure 17. To remove the mower blade, wedge a wooden block between the mower blade and the mower deck housing to keep the mower blade from turning, then remove the mower blade and the mower blade retaining hardware. Inspecting the Mower Blades Figure 17.
Regular Maintenance Sharpening the Mower Blade A CAUTION Avoid injury! Mower blades are sharp. • Always wear gloves when handling the mower blades. 1. 2. 3. 4. 5. • Always wear safety eye protection when grinding. Sharpen the mower blades with grinder, hand file, or electric blade sharpener. Sharpen the mower blade by removing an equal amount of material from each end of the mower blade. Keep the original bevel (A, Figure 20) when grinding. DO NOT change the mower blade bevel.
Regular Maintenance 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. ADDING FUEL Tire Pressure To add fuel: Front 40 psi (2,76 bar) 1. Stop the engine and allow to cool for at least 3 minutes. 2. Remove the fuel cap (see A, Figure 24). 3.
Regular Maintenance CHANGE ENGINE OIL & FILTER 1. Warm the engine by running for a few minutes. (Refer to the engine operator’s manual for oil & filter replacement instructions) 2.
