Installing Mulch Plug

The mulch kit consists of a mulch plug (part number
731-04651) which has to be installed on the cutting
deck of your tractor. Observe safety while installing
and later operating this mulch plug.

• Locate two rectangular holes on the cutting
deck surface.

• Pivot the discharge chute up to access the deck
opening. See Figure.

• Insert the mulch plug in the deck opening,
aligning the edge of the plug with the deck as
shown in the figure. Make sure the notches on
the plug are in the slots on the deck opening.

• Lightly tab on the plug with your hand so that the
notches fit properly under the chute tabs and the
plug is secure.

Operating Mulch Plug

The mulch plug allows the tractor to recirculate grass clippings into the lawn where they act as a natural fertilizer.

Observe following points for best results in mulching:

• Never attempt to mulch if the lawn is damp. Wet grass tends to stick to the underside of the deck preventing
proper mulching.

• Do not attempt to mulch more than 1/3 the total height of the grass or approximately 1-1/2 inches. Maintain a
slow ground speed to allow the grass clippings more time to be effectively mulched.

• Always position the throttle control lever of the tractor in the FAST (rabbit) position while mulching.

• To operate cutting deck without mulching, simply remove the mulch plug and lower the discharge chute slowly.
This will allow clippings to discharge from the side.
