Cutterbar Angle; Adjusting Cutterbar Angle: Mechanical; Adjusting Cutterbar Angle: Hydraulic - MacDon R113 Operator's Manual

3.15.2 Cutterbar Angle

The cutterbar angle adjustment can range from 0–5 degrees below horizontal using the mechanical center-link and
from 0–7 degrees below horizontal using the hydraulic center-link. Choose an angle that maximizes performance
for your crop and field conditions. A flatter angle provides better clearance in stony conditions, whereas a steeper
angle is required in down crops for better lifting action.

Adjusting Cutterbar Angle: Mechanical

DANGER
To avoid bodily injury or death from unexpected
startup of machine, always stop engine and remove
key from ignition before leaving operator's seat for
any reason.
1. Lower mower conditioner so that cutterbar is resting on
the ground.
2. Loosen nut (A).
3. Rotate the turnbuckle sleeve (B) so that the turnbuckle
decreases in length in order to decrease (flatten)
cutterbar angle.
4. Rotate the turnbuckle sleeve (B) so that the turnbuckle
increases in length in order to increase (steepen)
cutterbar angle.
5. Tighten nut (A) but do NOT overtighten. A slight tap
with a small hammer is sufficient.
6. Check cutting height and adjust if required.
7. Check mower conditioner float and adjust if required.

Adjusting Cutterbar Angle: Hydraulic

NOTE:
The cutterbar angle can be adjusted from the tractor
without shutting down the mower conditioner.
1. Operate the tractor
cylinder (C) retracts and moves gauge (D) toward
the green zone (A) in order to decrease (flatten)
cutterbar angle.
2. Operate the tractor
cylinder (C) extends and moves gauge (D) toward
the red zone (B) in order to increase (steepen)
cutterbar angle.
