To adjust the height of the drive control levers:
Remove the nuts from the control lever mounting bolts. 1.
See Fig. 6-5.
Remove the bolts and control lever and reposition to the 2.
second set of holes in the mounting block.
Reinstall the bolts and nuts, and tighten to 28-34 ft-lbs. 3.
If angular adjustments are also required, nuts can be 4.
tightened until snug at this point.
The same adjustments should be made to both sides of the
mower.
To adjust the front-to-rear angle of the control levers:
Loosen the nuts on the control lever mounting bolts, 1.
leaving the bottom one fairly snug. The bottom hole is
slotted, allowing the control lever to pivot on the top bolt.
Move control lever to the desired angle and tighten the
2.
nuts to 28-34 ft-lbs.
NOTE:
In the neutral position, the handles of the control
levers should be aligned with approximately a one inch
gap between the tips. Widen the gap by adding shim
washers to the top mounting bolt between the lap bar and
the mounting block.
Check the results of any adjustments to the conditions
3.
described above. Repeat any adjustment procedures as
required until all conditions are met.
Leveling the Mower Deck
When correctly adjusted the mower deck should be level side to
side, and the front of the deck should be approximately 1⁄4 ” lower
than the rear of deck.
NOTE: Check the tractor’s tire pressure before performing any
deck leveling adjustments. See the tire side wall for proper
inflation pressures.
Park the mower on a flat paved surface, engage the 1.
parking brake, shut off the engine, remove the key from the
ignition switch, disconnect the spark plug wires.
Using the deck lift pedal, position the mowing deck into
2.
the highest mowing position.
Measure blade-to-ground height at the front tip of the
3.
right blade. To obtain an accurate measure, align blades in
parallel with mower centerline, (i.e. front to back).
Measure blade-to-ground height at the front tip of the left
4.
blade. Be sure to measure at the blade tip with the blades
arranged in proper position.
With a
5. 3⁄4 ” wrench loosen the lower jam nut of the left side
of the lift link. To adjust the side of the deck up or down
turn the upper jam nut clockwise (to raise) or counter
clockwise (to lower) a few turns. See Fig. 6-6.
Measure the blade-to-ground height at the right rear blade 6.
tip. Again be sure to measure at the blade tip at the rear of
the right blade when aligned along the mower centerline.
The blade-to-ground height at the rear of the blade tip
should be approximately 1⁄4 ” higher than the front tip. This
is referred to as blade pitch. The same height difference
should be true for the left blade, measured front and back.
To change the pitch (front to rear), loosen the lower nuts
7.
on the rear Lift Links. With a few turns, adjust clockwise (to
raise) or counter clockwise (to lower) the upper nuts of the
rear Lift Links. Once the deck is adjusted, retighten lower
nuts.
