They are mainly aimed at farms that harvest fodder on medium plots of land. They are highly professional equipment, distinguished by the GRS series, the articulated 3° point linkage “3D” which gives the machine a perfect course on the ground thanks to the standard stabilizers. The range impeller in oil bath for a long life and low maintenance, has a slowed peripheral rotation, to ensure the integrity of the harvested product. The drive shaft is equipped with a free wheel to protect the bevel bevel gear from abrupt strokes. The double-twist mopping springs are mounted outside the soft-curved tube, rake the product from under the spring arm. The adjustment of the working height is convenient and intuitive to carry out. The wheel carrier axle has a wide track width. The tires are close to the raking springs, in order to follow the course of the terrain. In addition, the wheel carrier axle is equipped with the inclination of the impeller for a perfect raking result. The machine can be equipped with optional signaling tables and anterior touch wheel that guarantees a low collection of earth. Road transport is easy to prepare because with a simple split pin, the holder arms are extracted and placed in the appropriate positions on the frame.
