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 level adjusting bracket (See Figure 6-4).
Figure 6-4. Cutter Deck Adjustment
2. Loosen the two elastic stop nuts. Adjust the bolt up
or down on the adjustment bracket to adjust the
cutter deck until the distance from the bottom of the
cutter deck to the floor is the same as the
measurement on the RH side of the machine.
3. Tighten the two elastic stop nuts to secure the cutter
deck in the proper position.
Cutter Deck Pitch
The pitch of the cutter deck should be equal between the
front and rear 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 6-5).
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.
