Rotor pitch
To achieve optimum crop pickup, the rotors are inclined transversely
to the chassis. If the crop is not picked up cleanly, the raking quality
can be further improved by adjusting the rotor pitch.
Optimum raking quality is achieved when the tines in the front working
range and ahead of the crop depositor have the lowest possible
ground clearance (see illustration).
Adjusting the rotor
pitch
Before carrying out any adjustment work, you must secure the
machine:
Swing the machine into the headland position using the hydraulic
control device on the tractor.
Close the ball valve.
Secure the tractor against rolling away, shut off the engine and
remove the ignition key.
Secure the rotors with the relevant lifting accessories using
supports.
Then carry out one of the following steps:
Adjust the rotor pitch for a single axle
