5.7 Rotor coupling
When the conveying roller / cutting system is blocked,
the wedge clutch switches the torque to ‘zero’. If the
blockage can not be cleared by restarting the PTO shaft
at a speed less than 200 rpm, the conveying channel
is to be freed of blocked crop by reversing the
conveying roller.
Note:
Experience shows that when the bales are
nearly finished, the system can become
obstructed or the cam coupling can be
triggered.
It is possible to bind these bales without
having to eliminate the obstruction in the
vicinity of the cutting rotor. To do so,
disengage the cutting rotor by reverse
coupling, engage the propeller shaft at low
speed, bind the bale and eject. Then stop
the propeller shaft, engage the rotor again
and eliminate the obstruction at a low PTO
shaft speed.
Proceed as follows to reverse:
Switch off the PTO shaft, switch off the tractor
engine, remove the ignition key,
Disconnect the coupling claw via the lever,
Place the reversing lever onto the hexagon,
To reverse, turn anti-clockwise and convey the crop
out of the conveying channel by turning the
conveying roller back,
Fit lever to its support on the drawbar and re-
engage the claw clutch.
