Installation

Each cutting deck is suspended from a carrier frame.

Decks should be attached to the carrier frame using the

lower hole in deck bracket (Fig. 20).

The cutting deck carrier frame is attached to the lift arm

and allows the cutting deck to pivot on the lift arm pivot

shaft. Carrier frames are secured to lift arms as follows:

1. Carrier frames for the front three cutting decks (#1,

#4, and #5) have a thrust washer between the carrier

frame and the lift arm. The frame is secured to the lift arm

pivot shaft with a lynch pin (Fig. 19).

2. Carrier frames for the center two cutting decks (#2

and #3) have a thrust washer between the carrier frame

and the lift arm. The frame is secured to the lift arm pivot

shaft with a rebound washer and cap screw (Fig. 19).

3. Carrier frames for the rear two cutting decks (#6 and

#7 on the GM4700--D) have a compression spring and

thrust washer between the carrier frame and the lift arm.

The frame is secured to the lift arm pivot shaft with a flat

washer and lock nut (Fig. 19).
