5.8 Header Spring Float Assembly
The header spring float assembly allows the header to move vertically to respond to the contours of the field being
harvested. Take note of the tension position of the header spring float assembly when removing or installing these
assemblies.
5.8.1 Removing Header Spring Float Assembly
Ensure that all spring tension has been released before working on the float assembly.
WARNING
To avoid bodily injury or death from unexpected startup of machine, always stop the engine and remove the key from
the ignition before leaving the operator’s seat for any reason.
1. Attach the header to the combine feeder house and ensure that it is latched securely. It is not necessary to hook up
the driveline or the hydraulics. For instructions, refer to 3.10 Header Attachment and Detachment, page 38.
2. Lower the combine feeder house so that the front draper deck is rotated upward to the full floated-up position. The
header frame will be close to the ground and the coil spring will be fully collapsed.
NOTE:
The spring tension is factory-set to the second hole from the bottom on the float anchor.
3. Shut down the engine, and remove the key from the ignition.

5. Ensure that all spring tension is released from left spring
float assembly (A). Remove cotter pin (B), clevis pin (C), and
three flat washers (D).
NOTE:
When the spring tension is fully released, the spring coils
should be fully collapsed and the spring float assembly
should rock from side to side when moved by hand. If
pressure on the clevis pin persists, slightly raise or lower
the header.
