1. Start the engine.
2. Use HEADER TILT switches (A) on the ground speed
lever (GSL) to set the center-link to the mid-range position
(5.0) on the HarvestTouch
™
Display.
3. If checking float with a draper header attached, set the reel
to the normal operating position.
4. Using HEADER DOWN switch (B), lower the header fully.
5. Ensure the header is level with the ground with zero tilt.
6. Shut down the engine, and remove the key from the ignition.
7. Grasp one end of the header and lift. The force required to lift the header should be the same at both ends. For more
information, refer to Table

8. Restart the engine and adjust the float as needed. For instructions, refer to Setting Float, page 238 .
NOTE:
Increasing the float value on the HarvestTouch
™
Display makes the header feel lighter.
Setting Float
The float can be set for windrowing with the cutterbar on the ground or with the cutterbar off the ground (normally used
with the draper header).
The optimum float setting lets the header follow the contour of the terrain.
1. Set the center-link to the mid-range position ( 5.0 on the HarvestTouch
™
Display). For instructions, refer to 5.4.4
Adjusting Header Angle, page 244 .
