To adjust the front-to-rear angle of the control levers:
1.
Loosen the nuts on the control lever mounting bolts, leaving the
bottom one fairly snug. The bottom hole is slotted, allowing the
control lever to pivot on the top bolt.
2.
Move control lever to the desired angle and tighten the 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
control lever and the mounting block.
3.
Check the results of any adjustments to the conditions 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.
1.
Park the mower on a flat paved surface, engage the parking
brake, shut off the engine, remove the key from the ignition
switch, disconnect the spark plug wires.
2.
Using the deck lift pedal, position the mowing deck into the
highest mowing position.
3.
Measure blade-to-ground height at the front tip of the right blade.
To obtain an accurate measure, align blades in parallel with
mower centerline, (i.e. front to back).
4.
Measure blade-to-ground height at the front tip of the left blade.
Be sure to measure at the blade tip with the blades arranged in
proper position.
5.
With a 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 Figure 34.

6.
Measure the blade-to-ground height at the right rear blade 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.
7.
To change the pitch (front to rear), loosen the lower nuts 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.
8.
The final adjustment would be to set the Trailing Link by adjusting
the jam nuts on the threaded link. Loosen the jam nuts and tighten
the inner nut to achieve the correct length and belt tension. See
Figure 34.
9.
In many cases it will be necessary to adjust deck height using both
eyebolt adjustments and pitch adjustment to achieve the correct
blade-to-ground heights. If you remember that the front right blade
tip adjustment is fixed and you level to that height, adjusting the
decks will be simplified.
Adjusting the Belt Tension
To tighten or loosen the tension on the belt, tighten or loosen the jam
nuts on the U-rod, see Figure 34, until a ten-pound pull with a spring
scale deflects the belt about 1⁄2".
Brakes
The mower is equipped with internal gear/pawl brakes and will not
normally require maintenance. If they are not working properly, call
1-800-659-5917 to schedule service from Sears Parts & Repair.
