Mulching
Cub Cadet Series 1000 tractors are equipped with a
mulch kit which incorporates special blades, already
standard on your 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.
T
he mulch kit is installed at the factory. 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 8.
