Header Float; Header Angle - MacDon D65 Operator's Manual

DANGER
To avoid bodily injury or death from unexpected start-up or fall of raised machine, always stop engine,
remove key, and engage safety props before going under header for any reason. Refer to the windrower
operator's manual for instructions regarding the proper use and storage of header safety props.
2. Fully raise header, engage safety props, shut off engine, and remove key.
3. Remove lynch pin (A) at each skid shoe (B).
4. Hold shoe and remove pin (C) by disengaging frame
and then pulling away from shoe.
5. Raise or lower skid shoe to desired position using holes
in support as a guide.
6. Reinstall pin (C), engage in frame, and secure with
lynch pin (A).
7. Check that skid
same position.
8. Check header float as described in your windrower
operator's manual.

4.7.2 Header Float

D65 windrower headers are designed to ride on the skid shoes for cutting on the ground operation. The windrower
float system reduces the ground pressure so that the header floats over obstacles and follows ground contours
instead of being supported by the windrower lift cylinders. Refer to your M-Series Self-Propelled Windrower
Operator's Manual for details about header float adjustments.

4.7.3 Header Angle

Header angle is the angle between the drapers and the ground, and is adjustable to accommodate crop conditions
and/or soil type.
The header angle (A) is a critical factor for effective cutting
on the ground applications because it determines the
actual distance (B) between the sickle and the ground.
The header rotates about the point of skid shoe/ground
contact (C) by adjusting the length of the center-link
thereby adjusting the position of the guards and sickle.
Header angle (A) is synonymous with guard angle (D)
which is the angle between the guard upper surface and
the ground.
