85 lbf) and should be the
same at both ends.
6. Restart the engine, and adjust float as required. Refer to Setting the Float , page 73 .
NOTE:
Increasing the float value on the HPT makes the header feel lighter.
Setting the Float
The float can be set for windrowing with the cutterbar on the ground.
The optimum float setting lets the header follow the contour of the terrain. Proceed as follows:
