MTD 808H Series Operator's Manual page 17

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 front of the blade tip to
the ground and 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 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.

Deck Roller Height
To adjust the height of the rollers on the rear of the
mowing deck, proceed as follows:
• Place the deck lift lever in the bottom notch (lowest
position).
• Remove the clevis pins and hairpin clips from the
deck roller brackets on the left and right sides of the
cutting deck. See Figure 11.
• Position the deck roller brackets up or down
through the slots on the rear of the deck until
desired position is reached. Re-attach with clevis
pins and hairpin clips just removed. See Figure 11.
NOTE: Be certain that the left roller bracket and the
right roller bracket are set in the same position

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.
• 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.
• Loosen, but do NOT remove, the hex cap screw on
the left deck hanger bracket. See Figure 10B.
• Balance the deck by using a wrench to turn the
adjustment gear (found immediately behind the hex
cap screw just loosened) clockwise/up or
counterclockwise/down.
• The deck is properly balanced when both blade tip
measurements, taken earlier, are equal.
• Retighten hex cap screw on the left deck hanger
bracket when proper adjustment is achieved.
