Header Angle. MacDon D50 & D60

Header angle is the angle between the drapers and the ground, and is adjustable to accommodate crop conditions and/or soil type.

Guard angle is the similar to header angle which is the angle between the guard upper surface and the ground.

7.12.3.1 Angle Adjustment

The header angle is varied by adjusting the length of the top center-link (mechanical or hydraulic) between the windrower and the header.

Refer to “Header Angle in your Windrower

Operator’s Manual for adjustment details.

GUARD ANGLE HEADER ANGLE

Flatter header angles are recommended for normal crop conditions and for stony ground because it minimizes sickle section breakage, and reduces soil scooping or build-up at the cutterbar in wet conditions.

Steeper angles are recommended in “downed” crops for better lifting action, or for cutting close to the ground in hay for example. Refer to

Section 7.12.10 Reel Tine Pitch and Section

7.12.9 Reel Fore-Aft Position for adjustment details.

Header angle also affects the type of windrow that is laid. Refer to Section 7.15 WINDROW

TYPES. Choose an angle that maximizes performance for your crop and field conditions.
