Reading and understanding this operator's manual is a way to train yourself. Power equipment is only as safe as the operator.
SafetyRules& information SlopeOperation 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.
SafetyRules& information RetainingWalls,Drop-offs,andWater 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.
SafetyRules& information 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 1.
SafetyRulesandinformation 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.

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 appfied in specific sequences. To learn what combination and sequence of controls to use for various tasks see the OPERATION section. Ground Speed Control Choke Levers These levers control the ground speed of the rider.
Features& Controls B Hour Meter Fuel Tank 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. _PTO Fuel Level Gauge To remove the cap, turn counterclockwise. The fuel gauge is mounted in the fuel tank and indicates the amount of fuel in the tank.
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 1. While sitting in the operator's seat, engage the parking brake and make sure the PTO switch is disengaged and the motion control handles are locked in the NEUTRAL position. 2.
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. NOTE: To prevent pivoting directly on the tire tread, it is best to keep both wheels going at least slightly forward. NOTE: Changing the amount each lever is pulled-forward or back, changes the "pivot point"you turn on. Turning In-Place Executing Turns Figure 6.

Operation l \ / Figure 14. Release Belt Tension A. Idler Arm B. Stationary Idler Pulley 1" Figure 15. Proper Cutting Height MOWING Before mowing, set the cutting height as described in the Troubleshooting, Adjustments & Service section. Tall Grass Requires Incremental Cutting 1. Engage the parking brake. Make sure the PTO switch is disengaged and the motion control lever is in the NEUTRAL position.
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 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 Ibs (91 kg).
RegularMaintenance 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.
