1.
Remove the hex screws (a) and flat
washers (b) securing the drive control
lever (c) to the lower arm assembly (d).
Refer to Figure 4-8.

Reposition the drive control lever (c) to
align with the other set of holes in the
lower arm assembly (d) and insert the hex
screws (a) through the flat washers (b)
and then the drive control lever (c) then
into the lower arm assembly (d). Tighten
the hex screws (a) until snug. Repeat the
steps on the other control arm.
To adjust the drive control levers forward/
rearward, proceed as follows:
1.
Loosen the control lever knob (a) on the
side of the drive control lever (b). See
Figure 4-9.

2.
Place the drive control lever (b) in the
desired position.
3.
Secure in place by tightening the control
lever knob (a). See Figure 4-9.
4.
Note the relative position of the drive
control lever (b) to the pivot bracketnear
the seat, then repeat the previous steps
to reposition the other drive control lever
in approximately the same position.
5.
A fine-tuning adjustment can be made if
the drive control levers (b) are not lining
up correctly. Be certain that the control
lever knob (a) is secure and loosen the
two bolts securing the control lever
adjuster (c) to the lower arm assembly
(d). Pivot the control lever adjuster (c)
forward or rearward to align the drive
control levers (b). When the drive control
levers (b) are aligned, re-tighten the
bolts to secure the drive control lever (b).
Deck Leveling
NOTE: Check the tractor's tire pressure before
performing any deck leveling adjustments. Refer
to Tires for information regarding tire pressure.
Leveling the Deck (Side-to-Side)
NOTE: Check the tractor's tire pressure before
performing any deck leveling adjustments. Refer
to Tires for information regarding tire pressure.
Always level the deck side-to-side before front
to rear.
If the cutting deck appears to be mowing
unevenly, a side-to-side adjustment can be
performed. Adjust if necessary as follows:
1.
With the tractor parked on a firm, level
surface, place the deck lift handle in
a middle mowing position and rotate
both outside blades so that they are
perpendicular with the tractor.
2.
Measure the distance from the outside
of the left blade tip to the ground and
the distance from the outside of the
right blade tip to the ground. Both
measurements taken should be equal. If
they're not, proceed to the next step.
3.
Loosen the lower nut (a) on the
adjustable lift link (b) attached to the
deck lift arm (c) to lower the deck and
tighten the upper nut (d) to secure the
deck in place, loosen the upper nut (d)
then tighten the lower nut (a) to secure
the deck in place. See Figure 4-10.

4.
The deck is properly leveled when both
blade tip measurements are equal.
Leveling the Deck (Front-To-Rear)
NOTE: Check the tractor's tire pressure before
performing any deck leveling adjustments.
Refer to Tires for information regarding tire
pressure. Always level the deck side-to-side
before front to rear.
The front of the deck should be between
1⁄4-3⁄8" lower than the rear of the deck. Adjust if
necessary as follows:
1.
Park the tractor on a firm, level surface
and place the deck lift handle in a
middle position.
2.
Rotate the blade nearest the discharge
chute so that it is parallel with the tractor.
3.
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.
4.
Determine the approximate distance
necessary for proper adjustment and
proceed, if necessary.
5.
Using a wrench, raise the front of deck
by loosening the lock nuts to the front
of the pivot pin (a) and then tighten the
jam nuts on the back of the pivot pin (a)
to raise the front of the deck and secure
in place. See Figure 4-11.
(a)
Figure 4-11
6.
Using a wrench, lower the front of deck
by loosening the jam nuts on the back
of the pivot pin (a) and then tighten the
lock nut on the front of the pivot pin (a)
to lower the front of the deck and secure
in place. See Figure 4-11.
7.
The deck is properly leveled when the
front tip of the blade is 1⁄ 4 " lower than the
rear tip. Retighten the hex bolt on the
left rear deck hanger links when proper
adjustment is achieved.
Adjusting the Front Gauge Wheels
WARNING!: Keep hands and
feet away from the discharge
opening of the cutting deck.
The front gauge wheels on the mower deck are
an anti-scalp feature, and should not ride on
the ground. The front gauge wheels should be
approximately 1⁄4-1⁄2" above the ground when
the deck is set in the desired height setting.
Using the deck lift handle, set the deck in the
desired height setting, then check the gauge
wheel distance from the ground below. If
necessary adjust the front gauge wheels as
follows:
1.
Visually check the distance between the
front gauge wheels and the ground. If
the gauge wheels are near or touching
the ground, they should be raised. If
more than 1⁄2" above the ground, they
should be lowered.
