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

3.16.2 Mower Conditioner Angle

Mower conditioner (or cutterbar) angle adjustment can range from 0–5° below horizontal using the mechanical
center-link and from 0–7° 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.
DANGER
Stop engine and remove key from ignition before leaving operator's seat for any reason. A child or even a
pet could engage an idling machine.

Adjusting Mower Conditioner Angle: Mechanical

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)
mower conditioner angle.
4. Rotate the turnbuckle sleeve (B) so that the turnbuckle
increases in length in order to increase (steepen)
mower conditioner angle.
5. Tighten nut (A), but do NOT over-tighten. A slight tap
with a small hammer is sufficient.
6. Check cutting height and readjust if required.
7. Check mower conditioner float, and adjust if required.

Adjusting Mower Conditioner Angle: Hydraulic

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