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 9.
SECTION 7: 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.
Leveling the Deck
NOTE:
Check the tractor’s tire pressure before
performing any deck leveling adjustments. Refer to
TIRES in the maintenance section of this manual for
further information regarding tire pressure.
Front To Rear
The front of the cutting deck is supported by a stabilizer
bar that can adjusted to level the deck from front to rear.
The front of the deck should be between 1/4-inch and
3/8-inch lower than the rear of the deck. Adjust if
necessary as follows:
•
With the tractor parked on a firm, level surface,
place the deck lift lever in the top notch (highest
position) and rotate the blade nearest the discharge
chute so that it is parallel with the tractor.
•
Measure the distance from the front of the blade tip
to the ground and the rear of the blade tip to the
ground.
•
The first measurement taken should be between
1/4" and 3/8" less than the second measurement.
•
Determine the approximate distance necessary for
proper adjustment and proceed, if necessary, to the
next step.
•
Loosen the two jam nuts on the rear side of the
deck stabilizer bracket. See Figure 10A.
•
Locate the two lock nuts on the opposite side of the
stabilizer bracket. See Figure 10A. Tighten the lock
nuts to raise the front of the deck; loosen the lock
nuts to lower the front of the deck.
•
Retighten the two jam nuts loosened earlier when
proper adjustment is achieved.
Side to Side
If the cutting deck appears to be mowing unevenly, a
side to side adjustment can be performed. Adjust if
necessary as follows:
•
With the tractor parked on a firm, level surface,
place the deck lift lever in the top notch (highest
position) and rotate both blades so that they are
perpendicular with the tractor.
