OPERATING THE MOWER CONDITIONER
7.6 Mower Conditioner Angle
mower conditioner (or cutterbar) angle can be varied from 0–5° below horizontal with the mechanical center-link and
0–7° below horizontal with 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 while a steeper angle is required in down crops for better
lifting action.
7.6.1 Adjusting Mower Conditioner Angle: Mechanical (if equipped)
Follow these steps to adjust mower conditioner angle on a mower conditioner with mechanical adjustment:
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.
1. Lower mower conditioner so that cutterbar is resting on
the ground.
2. Loosen nut (A).
3. To decrease (flatten) mower conditioner angle, rotate
the turnbuckle sleeve (B) so that the turnbuckle
decreases in length.
4. To increase (steepen) mower conditioner angle, rotate
the turnbuckle sleeve (B) so that the turnbuckle
increases in length.
5. Snug up nut (A) but do not over-tighten. A slight tap
with a small hammer is sufficient.
