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

4. Raise the stabilizer wheels or slow speed transport wheels fully (if installed). For instructions, refer to the following:
•
Adjusting Stabilizer Wheels, page 54
•
Adjusting Stabilizer/Slow Speed Transport Wheels, page 52
5. Remove lynch pin (A) from each skid shoe (B).
6. Hold shoe (B) and remove adjustment pin (C) by
disengaging it from the frame and pulling it away from
the shoe.
7. Raise or lower skid shoe (B) to achieve the desired position
using the holes in the support as a guide.
8. Reinstall pin (C), engage it in the frame, and secure it with
lynch pin (A).
9. Check that all skid shoes are equally adjusted.
10. Check the header float as described in your windrower
operator's manual.

3.7.4 Header Float

D65 Draper Headers are designed to ride on the skid shoes when cutting on the ground. 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 windrower operator's manual for details about header float adjustments.

3.7.5 Header Angle

Header angle can be adjusted to accommodate different crop conditions and/or soil types.
Header angle (A) controls the distance (B) between the knife
and the ground and is a critical component for effective cutting
on the ground. Adjusting the center-link determines the position
of the knife and guards and pivots the header at the point of
skid shoe/ground contact (C).
Header angle (A) is equal to guard angle (D) which is the angle
between the upper surface of the guards and the ground.

Controlling Header Angle

Header angle varies by adjusting the length of the top center-link (mechanical or hydraulic) between the windrower and
the header.
Refer to your windrower operator's manual for adjustment details.
