OPERATING VARIABLES (continued)
5. CUTTERBAR ANGLE
Cutterbar angle can be varied from 6
°
to 12
°
below horizontal. Choose an angle that maximizes performance
for your crop and field conditions. A flatter guard angle provides better clearance in stony conditions while a
steeper guard angle is required in down crops for better lifting action.
To adjust cutterbar angle:
a. Loosen nut (A).
b. To decrease (flatten) cutterbar angle, turn nut (B) clockwise.
c. To increase (steepen) cutterbar angle, tun nut (B) counter-clockwise.
d. Tighten nut (A) to 160 ft.lbs. (210 N.m)
After adjusting cutterbar angle:
a. Check cutting height and adjust if required. See "Cutting Height" in this section.
b. Check header float and adjust if required. See "Header Flotation" in this section.
