Rotor pitch / fine adjustment

If uneven raking becomes a problem, the rotor
pitch should be readjusted.
Functional description (fig. 4-3):
In the sectors A (rh rotor) and B (lh rotor) of
the rotor periphery, tines are raking more crop
than in the remaining area (raking speed is
reduced in the sectors A and B due to ground
speed and rotor rotation).
Tilting the rotors downward (C) will increase
the crop volume in each of the two sectors.
This can be done by adjusting the wheel axles.
Best results are obtained by tilting the rotors
abt. 20 mm downward in both sectors
concerned.
Adjusting procedure (fig. 4-4):
Danger!
Work may only be carried out with
the machine at a standstill. Remove
the ignition key. Secure the tractor
in order to prevent it from rolling
away!
Lifting the front / rear rotor
Front rotor: Lift the front rotor 20 cm
clear of the ground and close the
shut-off tap.
Rear rotor: Lift the front rotor
completely and lock; lower the rear
rotor until it is 20 cm clear of the
ground.
Before starting work check tyre pressure (1.5
bar), remove tine arms and lock rotors by
closing the ball cock on the hydraulic line.
Adjust rotor pitch by installing 5 mm shims (D)
as required at the top or lower side of the
axle support (fig. 4-3a).
Position axle stubs so as to obtain the following
ground clearance of the tine tips:
left hand rotor: tines slightly touching the
ground when delivering the crop; right hand
rotor: abt. 20 mm.
