6.6 CUTTER DECK ADJUSTMENTS

Cutter deck level, pitch and height are set at the factory.
However, if these adjustments should ever need to be
made, the following procedures will aid in obtaining the
proper cutter deck adjustment.

-NOTE-

Before proceeding with the cutter deck
adjustments, be sure that all tires are properly
inflated.

Cutter Deck Level

The cutter deck should be level from side-to-side for
proper cutting performance. To check for level, be sure
that the mower is on a flat, level surface, the tires are
properly inflated and the cutter deck is set at the most
common cutting height that you will use. On the RH side
of the machine, check the distance from the top of the
cutter deck to the floor. Next check the distance from
the top of the cutter deck to the floor on the LH side of
the machine. Both measurements should be the same.
If the two measurements are different, the cutter deck
level must be adjusted as follows:

1. On the front LH side of the cutter deck locate the

cutter deck adjusting bolt. (See Figure 6-4)

Figure 6-4. Cutter Deck Adjustment

2. Loosen the elastic stop nut and move the bolt up or

down in the slot to adjust the cutter deck until the
distance from the top of the cutter deck to the floor
is the same as the measurement on the RH side of
the machine.

3. Tighten the elastic stop nut to secure the cutter deck

in the proper position.

Cutter Deck Pitch

The pitch of the cutter deck should be 1/4" down toward
the front of the cutter deck for proper cutting
performance. To check for proper deck pitch, be sure
that the mower is on a flat, level surface and the tires are
properly inflated.

Check the distance from the top of the cutter deck to the
floor at the rear RH side of the cutter deck directly
behind the cutter deck hanging chains. Next check the
distance from the top of the cutter deck to the floor at
the front RH side of the cutter deck directly in front of
the cutter deck hanging chains. The measurement at the
front of the cutter deck should be the same as the rear of
the deck. Make these measurements at the LH side of
the cutter deck also. If the measurement at the front of
the deck is not the same, the cutter deck pitch must be
adjusted as follows:

1. Loosen the lock nuts on both adjusting rods.

(See Figure 6-4)

2. Using an adjustable jaw pliers, turn the adjusting rods

on the non threaded portion of the rod until the deck
is equal front to back on both the RH and the LH
side of the cutter deck. Tighten both lock nuts.

-NOTE-

To prevent the cutter deck from teetering, all four
cutter deck hanging chains must have tension on
them. If all four chains do not have tension on
them and the deck teeters, you must readjust the
cutter deck as outlined in the procedures above.
All measurements should be taken from the top
edge of the deck as the Advantage+ decks have
an uneven bottom edge.
