MacDon R85 Rotary Disc 16 Foot Self-Propelled Windrower Headers - Manual (Page 86)

OPERATING THE HEADER
6.6 Header Angle
Header (or cutterbar) angle can be varied from 0–8° below horizontal.
Choose an angle that maximizes performance for your crop and field conditions.
A flatter angle provides better clearance in stony conditions while a steeper angle is required in down crops for better
lifting action.
The header angle may be hydraulically adjusted from the
windrower cab using the hydraulic cylinder (A) without
shutting down the windrower.
Refer to your MacDon self-propelled windrower
operator’s manual.
