Usage Features

Starting: The mower features an electric start, requiring a charged battery. It also has a manual recoil starter as a backup. To start, the operator must engage the control bar and pull the starter rope (or press the electric start button).
Operating Modes:
- Mulching: The mower can be converted to mulching mode by installing a mulcher door and removing the grass catcher. This mode finely chops grass clippings and returns them to the lawn as natural fertilizer.
- Bagging: The grass catcher can be attached to collect clippings.
- Side Discharging: A discharge deflector can be installed for side discharge, allowing clippings to be expelled from the side of the mower.
Cutting Height Adjustment: The wheel height adjusters allow the operator to set the desired cutting height. The manual recommends adjusting all four wheels to the same height.
Operator Presence Control Bar: This safety feature requires the operator to hold the control bar against the upper handle for the engine to run. Releasing the bar stops the engine and blade.
Mowing Tips:
- Mulching: For best performance, keep the lawn free of trash, maintain a clean underside, and avoid cutting more than 1/3 of the grass blade at a time.
- General Mowing: Overlap cutting paths, avoid cutting wet grass, and vary mowing patterns to prevent matting.
- Discharge: For side discharge, direct clippings away from obstacles and areas where they are not desired.
Fuel and Oil: Use unleaded regular gasoline with up to 10% ethanol (E10). Do not use E15 or E85. Check oil level before each use and add oil as needed.
