4.4.2 Header Float
The header float feature allows the header to follow the contours of the ground closely as the windrower moves forward.
The header is able to respond to sudden changes in elevation or obstacles quickly. The float setting is ideal when the
cutterbar rides along the ground with minimal bouncing, and without scooping or pushing soil.
IMPORTANT:
• Configure the header float setting to be as light as possible, while limiting the amount of bouncing produced by the
header. Doing so will reduce the amount of wear placed on knife components, and will prevent the header from
scooping soil.
• Prevent the header from bouncing excessively by operating at a slower ground speed when the float setting is light. A
bouncing header results in raggedly cut crop.
• Before setting the header float, install all of the header kits (for example: upper cross auger; skid shoes; slow speed
transport kit). If the Slow Speed Transport (SST) tow-bar will be stored on the header during operation, set the float
with the tow bar in place.
• Adjust the float when adding or removing optional attachments which change the weight of the header.
Float Operating Guidelines
Follow these instructions to get the best performance out of the header float system.
When working with the cutterbar on the ground:
• Set the center-link to the mid-range position (5.0 on cab display module [CDM]). For instructions, refer to 4.4.5
Adjusting Header Angle, page 202.
• When the header is level with the ground, minimize the scooping of rocks by adjusting the header skid shoes
downward to raise the guards.
• To prevent the header from pushing soil, adjust the height or the angle of the header.
When cutting with a draper header’s cutterbar off the ground:
• Set the center-link to the mid-range position (5.0 on CDM). For instructions, refer to 4.4.5 Adjusting Header Angle, page
202.
• Balance the amount of header weight carried by the float and by the stabilizer wheels. For instructions, refer to your
draper header operator’s manual.
• Use the CDM’s controls to automatically maintain the proper cutting height. For instructions, refer to 4.4.6 Controlling
Cutting Height, page 205.
