    During Operation

    During Operation Safety

    General Safety

    • Wet grass or leaves can cause serious injury if you slip and contact the blade. Avoid mowing in wet conditions.

    • Before you start the machine, ensure that all drives are in neutral.

    • Keep away from holes, ruts, bumps, rocks, and other hidden hazards. Use care when approaching blind corners, shrubs, trees, tall grass or other objects that may hide obstacles or obscure vision. Uneven terrain could overturn the machine or cause you to lose your balance or footing.

    • Shut off the machine and disengage the drive to the cutting unit after striking a foreign object or if an abnormal vibration occurs. Inspect the cutting unit for damage and make repairs before starting and operating the machine.

    • Be alert, slow down, and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.

    • Do not use the machine as a towing vehicle.

    • Never raise the mower deck with the blades running.

    • Be aware of the mower discharge path and direct discharge away from others. Avoid discharging material against a wall or obstruction as the material may ricochet back toward the operator. Stop the blades, slow down, and use caution when crossing surfaces other than grass and when transporting the mower.

    • Do not leave a running machine unattended.

    • Be alert and shut off the machine if children enter the area.

    Slope Safety

    • Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution. Before using the machine on a slope, do the following:

      • Review and understand the slope instructions in the manual and on the machine.

      • Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.

    • Operate across slopes, never up and down. Avoid operation on excessively steep or wet slopes.

    • Identify hazards at the base of the slope. Do not operate the machine near drop-offs, ditches, embankments, water, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard. Use a walk-behind machine or a handheld tool to operate in these areas.

    • Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction; turn slowly and gradually.

    • Do not operate a machine under any conditions where traction, steering or stability is in question. Be aware that operating the machine on wet grass, across slopes or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering. The machine can slide even if the drive wheels are stopped.

    • Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.

    • Use extra care while operating with accessories or attachments. These can change the stability of the machine and cause a loss of control. Follow directions for counterweights.

    • If you lose control of the machine, step away from the direction of travel of the machine.

    Starting the Machine
