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

3. Remove the lynch pin (A) from each skid shoe (B).
4. Hold the shoe (B) and remove the pin (C) by
disengaging from the frame and pulling away from
the shoe.
5. Raise or lower the skid shoe (B) to achieve the desired
position using the holes in the support (D) as a guide.
6. Reinstall pin (C), engage in frame, and secure with
lynch pin (A).
7. Check that all of the skid shoes are adjusted to the
same position.
8. Check the header float as described in your windrower
operator's manual.

3.7.2 Header Float

D65 windrower 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.

3.7.3 Header Angle

Header angle is the angle between the drapers and the ground and is adjustable to accommodate crop conditions
and/or soil types.
Header angle (A) is a critical factor for effectively cutting on
the ground because it determines the actual distance (B)
between the knives and the ground. The header rotates at
the point of skid shoe/ground contact (C) by adjusting the
length of the center-link thereby adjusting the position of
the guards and knives.
Header angle (A) is synonymous with 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.
