Mulching
Model 1525 & 1527 lawn tractors come 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 blown 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.
Figure 11
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 11.
SECTION 6: MAKING ADJUSTMENTS
WARNING:
Never attempt to make any
adjustments while the engine is running,
except where specified in the operator’s
manual.
WARNING:
Disconnect the spark plug
wire(s) and ground against the engine before
performing any adjustments, repairs or
maintenance.
Carburetor
The carburetor is a main component of the emission
control system and should be adjusted or serviced only
by a qualified mechanic.
The carburetor’s main fuel jet is fixed. The low idle fuel
adjusting needle has only minimal adjustment and
normally does not need adjustment.
If the engine is hard to start, runs roughly, or stalls at
low idle speed, contact your Cub Cadet dealer for
carburetor service.
