Soil working machine with ground contact drive - has contra-rotating rotors with radial arms mounting long staggered blades (NL 16.10.79)

摘要

The machine has two working rotors (14, 16A) which turn about parallel axes. The rotors have long blade attachments which are also parallel to the axes of rotation. One of the implements can be driven by ground contact. Alternatively, the rotor (14) can be connected with a device driven by ground contact. This describes a path which is partly within the path described by the rear ends of tools (6) of the positively driven device.
