Mulch Plug (if equipped)
On tractor models so equipped, a mulch plug can be found
within the cutting deck's discharge opening.
NOTE: Refer to Mulching in the "Operation" section of this
manual for more detailed information.
If you'd prefer to operate the cutting deck without mulching,
simply remove the mulch plug by unthreading the plastic
wing nut which fastens it to the cutting deck. This will allow
the clippings to discharge out of the discharge opening during
operation. See Figure 3-7.

like information regarding adding a mulching system for your
model of tractor.

maintained at all times. Never exceed the maximum
inflation pressure shown on the sidewall of the tire.
The recommended operating tire pressure is:
Approximately 10 psi for the rear tires
Approximately 14 psi for the front tires
IMPORTANT: Refer to the tire sidewall for exact tire
manufacturer's recommended or maximum psi. Do not
overinflate. Uneven tire pressure could cause the cutting deck to
