Adjusting Carrier Frame Height

Raising carrier frame height is recommended if machine is operated mainly with side gauge shoes fully extended (for highest cut). Upfloat can also be increased by raising carrier frame.

IMPORTANT: Adjust tilt control cylinder to a length of 720 mm (28.3 in.) or less when operating machine with carrier frame in the "raised" position to prevent float spring problems. (See Adjusting Cut Height in this section.)

Impeller conditioner; High carrier frame position should not be used with header tipped forward. Float springs may disengage from header.

To adjust carrier frame height:

1. Put wooden blocks under each end and along center of cutterbar frame.

2. Lower machine down on blocks.

3. Shut off tractor engine.

causym CAUTION: To avoid personal injury, support float springs before releasing tension completely. Float springs are heavy and will swing away from machine when disconnected.

4. Remove crank (A) from storage position and turn handle counterclockwise to release float spring tension.

5. Remove cap screw and nut, if equipped. Disconnect float springs (B).

6. Repeat Steps 4 and 5 on opposite side.
