Double rotary swath harvester with wheeled chassis

摘要

The two rotors (4), suspended from two spaced apart points, have arms carrying tines. The rotor arms are coupled to the power take-off shaft of a tractor. the rotors are guided over the ground by support wheels on two axles and are suspended on one axle parallel to the lengthwise centre plane, and on an axle parallel to the ground and at right-angles to the first. The suspension point at the front in the direction of travel has a ball-and-socket joint. The back suspension point positioned on a parallel to the lengthwise centre plane is formed by a roller fixed to a lifting arm (8) and guided in a vertical slide piece of the rotor head. The swivel angle is restricted by the transverse axle at right angles to the direction of travel.
