Mulching
(If Equipped)
Select models come equipped with a mulch kit which
incorporates special blades, already standard on the
tractor, in a process of recirculating grass clippings
repeatedly beneath the cutting deck. The ultra-fine
clippings are then forced back into the lawn where they
act as a natural fertilizer. Observe the following points
for the best results when mulching.
• Never attempt to mulch if the lawn is damp. Wet
grass tends to stick to the underside of the cutting
deck preventing proper mulching of the clippings.
• Do NOT attempt to mulch more than 1/3 the total
height of the grass or approximately 1-1/2 inches.
Doing so will cause the clippings to clump up
beneath the deck and not be mulched effectively.
• Maintain a slow ground speed to allow the grass
clippings more time to effectively be mulched.
• Always position the throttle control lever in the
FAST (rabbit) position and allow it to remain there
while mowing. Failing to keep the engine at full
throttle places strain on the tractor's engine and
does not allow the blades to properly mulch grass.
NOTE:
It is not necessary to remove the discharge
chute to operate the mower with the mulch kit installed.
• 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 the
side. See Figure 14.

Headlights
On some models, the lamps are ON whenever the
tractor's engine is running. On other models, the lamps
are ON whenever the ignition key is moved out of the
STOP position.
On all models, the lamps turn OFF when the ignition
key is moved to the STOP position.
