Safety

Rear Discharge or Mulch Grass

Warning

Without the grass deflector mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death.

  • Never remove the grass guard from the mower because the grass guard routes material down toward the turf. If the grass guard is ever damaged, replace it immediately.

  • Never put your hands or feet under the mower.

  • Never try to clear the discharge area or mower blades unless you engage the parking brake, disengage the power take off (PTO) lever, shutoff the engine, remove the ignition key, and wait for all motion to stop. Also pull the wire off the spark plug(s).

Ensure that the mower has the rear grass guard to disperses clippings to the rearward and down toward the turf, while in rear discharge mode.

To mulch grass clippings, install the baffles on the mower deck as instructed in the following procedures.

Operation

Selecting the Proper Height of Cut

Remove approximately 25 mm (1 inch) or no more than 1/3 of the grass blade when cutting. In exceptionally lush and dense grass you may need to raise the height of cut setting or convert to side discharge or bagging.

Mowing in Extreme Conditions

Air is required to cut and recut grass clippings in the mower housing, so do not set the height-of-cut too low or fully surround the housing by uncut grass. Always try to keep the back of the mower deck free from uncut grass, allowing air to be drawn into the housing. When making an initial cut through the center of an uncut area, operate the machine slower and back the machine if the mower starts to clog.

Mowing at Correct Intervals

Grass grows at different rates at different times of the year. To maintain the same cutting height, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height, then mow again 2 days later at a lower height setting.

Mowing with Sharp Blades

A sharp blade cuts cleanly and without tearing or shredding the grass. A dull blade tears and shreds the grass. Tearing and shredding causes the grass to turn brown at the edges, which impairs growth and increases susceptibility to disease.

Cleaning the Mower Deck

Maintenance Service IntervalMaintenance Procedure
After each use
  • Clean the underside of the mower deck.
  • To ensure optimum performance, clean the underside of the mower deck after each use.

    Important: Do not use brackish or reclaimed water to clean the machine.

    Note: If residue grass builds up in the mower deck, cutting performance decreases.
