InstallingTheMulchingPlug(If Equipped)
NOTE: Your mulching plug may already be installed
on the deck.
Some lawn tractors come equipped with a mulch kit
which incorporates special blades, already standard on
all tractor, in a process of recircuiating 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
recommendations for the best results when mulching.
NOTE: The mulch kit is installed on models equipped
with a 39" or 42-inch deck. It is packed separately (with
an instruction sheet) in the crate on models equipped
with a 46-inch deck.
10
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 propedy 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 itto the cutting deck. This will allow
the clippings to discharge out the side. See Figure 6.
