Installation

Preparing the Machine

Warning

The machine could fall onto someone and cause serious injury or death.

  • Always shut off the engine, engage the parking brake, and remove the key before performing any maintenance on the mower.

  • Use extreme caution when the machine is raised and supported on its back. The blades and moving parts are exposed and could cause injury.

  • Use this position only for cleaning, removing blades or baffles, and maintenance.

You can raise the front of the mower and support it using jack stands to access underneath the machine.

  1. Disengage the PTO, move the motion-control levers to the NEUTRAL-LOCK position, and engage the parking brake.

  2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

  3. Raise the front of the machine and support it with jack stands.

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

  5. Clean the machine of any debris on the deck to ease installation.

Operation

Positioning the Flow Baffle

The following figures are recommendations only. Adjustments vary by grass type, moisture content, and the height of the grass.

Note: If the engine power draws down and the mower ground speed is the same, open the baffle.

The suggested uses for the positions are as follows:

Position A:

  • Short, light grass mowing conditions

  • Dry conditions

  • Smaller grass clippings

  • Propels grass clippings farther away from the mower

Position B:

Use this position when bagging. Always align it with the blower opening.

Position C:

  • Tall, dense grass mowing conditions

  • Wet conditions

  • Lowers the engine-power consumption

  • Allows increased ground speed in heavy conditions

Refer to the following figures for the position location.
