  • the pivoting angle of the supporting beam parts upwards from the working position is advantageously 70 °. This angle is limited by a stop surface on the drive housing 2, 3 and by the predetermined angular position of the turntable 24. This ensures that even a simple universal joint 29 can withstand the rotation and pivoting movement without damage when the PTO shaft is not switched off.
  • the housings 2, 3 compression springs 26 which cooperate with the pivot levers 21 and act on them in such a way that the supporting beam parts 12, 13 are rotated with their associated tine rotors so far that they then move into the working position due to the force of gravity become.
