Safety

Using the Side-Discharge Mode or Mulching Grass

Danger

Without a grass deflector, discharge cover, or a complete grass-catcher assembly 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 deflector from the mower deck because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately.

  • Never put your hands or feet under the mower deck.

  • Never try to clear the discharge area or mower blades unless you move the blade-control switch (PTO) to the OFF position, rotate the key switch to the OFF position, and remove the key from the key switch.

  • Make sure that the grass deflector is in the down position.

Installation

Preparing the Machine

  1. Park the machine on a level surface.

  2. Move the motion-control levers to the NEUTRAL-LOCK position.

  3. Engage the parking brake.

  4. Shut off the engine and remove the key.

  5. Thoroughly clean the mower deck. Remove all debris to ensure that the baffles will fit properly.

  6. Repair all bent or damaged areas of the mower deck and replace any missing parts.

Removing the Existing Blades

Warning

The blades are sharp. Contact with a sharp blade can cause serious personal injury.

Wear gloves or wrap the sharp edges of the blade with a rag.

Refer to the Operator’s Manual for instructions on removing the blades.

The recycler blades are sold separately. Contact your Authorized Service Dealer.

Installing the New Blades

Warning

The blades are sharp. Contact with a sharp blade can cause serious personal injury.

Wear gloves or wrap the sharp edges of the blade with a rag.

Refer to the Operator’s Manual for instructions on installing the blades.

The recycler blades are sold separately. Contact your Authorized Service Dealer.

Tightening all Fasteners

  1. Tighten all nuts and bolts for the baffles (Figure 2, Figure 3, Figure 6, Figure 7, and Figure 9).

  2. Rotate the blades and ensure that there is clearance between the blades and the baffles. If there is interference, loosen the baffle and reposition it.

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 surround the housing by uncut grass. Always try to have 1 side of the mower housing 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 up 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.

After Operating

To ensure optimum performance, clean the underside of the mower housing after each use. If residue builds up in the mower housing, cutting performance decreases.
