    Operator Safety Operator Safety Read the Manual The operator’s manual contains important safety information you need to be aware of BEFORE you operate your unit as well as DURING operation. Safe operating techniques, an explanation of the product’s features and controls, and maintenance information is included to help you get the most out of your equipment investment.
  • Page 5 Thrown Objects This unit has spinning mower blades. These blades can pick up and throw debris that could seriously injure a bystander. Be sure to clean up the area to be mowed and remove objects that could be thrown by the blade BEFORE you start mowing.
  • Page 6 Operator 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.

  • Page 25: Mowing Methods

    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).

  • Page 26: Attaching A Trailer

    Operation Proper Mulching 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.
