Rotary tedder PRONAR PWP770C
The rotary tedder PRONAR PWP770C is designed for tedding short-stemmed green plants and mowed hay, as well as for spreading and evenly distributing cut crops across fields and meadows.
With a working width of 7.7 m, and six rotors, each equipped with seven arms with double tines, the machine delivers excellent performance — up to 7.7 ha/h.
Its active spring suspension ensures perfect ground adaptation, while the simple structure and easy operation allow the operator to quickly adjust the desired settings.
The required tractor power is 37 kW (50 HP), and the machine weighs 915 kg. It can be attached to any tractor with a three-point linkage, Cat. I or II.
The PWP770C version is an upgraded design of the PWP770, featuring centralized border tedding controlled by a single lever (with optional hydraulic control).
