Dominoni FREE SUN sunflower header has been designed to last in time and to minimise maintenance and repair work. It can be adapted to any kind of combine thanks to a connection with adjustable inclination. Both the auger and the reel have torque limiters. The auger is very large in order to favour a regular supply of product. The cutting height of the notched reel can be easily adjusted simply by rotating a screw. The belt tender has a great diameter and maintains a constant traction by means of a spring. A notched roller (optional) placed under the blade accelerates the dropping of flower heads and prevents the eradication of sunflower plants, thus considerably increasing production capacity.
