Leveling The Deck; Side To Side Leveling; Front To Rear Leveling - Cub Cadet 900 Series Professional Shop Manual

Leveling the deck

For the best quality cut, the deck must be level side to
side and the front of the deck should be 1/4" - 3/8"
lower than the rear of the deck.
To level the deck:
NOTE: Check the tractor's tire pressure before
performing any deck leveling adjustments. The
recommended operating tire pressure is:
• Approximately 10 psi for the rear tires
• Approximately 14 psi for the front tires

Side to Side Leveling

1. With the tractor parked on a firm, level surface,
move the deck to the mid height position (third or
fourth notch) using the deck lift lever. Rotate
both blades so that they are perpendicular with
the tractor frame.
NOTE: On the timed decks, rotate one blade
perpendicular to the frame, perform step two
then repeat this procedure on the other blade.
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
are not, note whether the left side of the deck is
lower or higher and proceed to the next step.
NOTE: Use of Cub Cadet deck leveling gauge,
part number 490-900-0041, will make measuring
the blade tip height easier. See Figure 8.27.

3. Working from the left side of the tractor, loosen,
but do not remove, the bolt on the left deck
hanger bracket. See Figure 8.28.

4. To even the deck turn the adjustment gear,
located immediately behind the bolt, clockwise
(rearward) to raise the left side of the deck. Turn
the gear counter-clockwise (toward front) to
lower the left side of the deck. See Figure 8.28.
5. The deck is properly leveled when both blade tip
measurements, as described earlier, are equal.
6. Retighten the bolt on the left deck hanger
bracket when proper adjustment is achieved.

Front To Rear Leveling

The front of the cutting deck is supported by an adjust-
able front deck hanger rod. This rod can be adjusted to
set the front to rear pitch of the deck. 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 fol-
lows:
1. With the tractor parked on a firm, level surface,
move the deck to the mid height position (third or
fourth notch) using the deck lift lever. Rotate the
blade nearest the discharge chute so that it is
parallel with the tractor frame.
