Short disk-harrow Rubin even in difficult soil conditions provides intensive, homogeneous mixing of organic matter and soil up to a working depth of about 16 cm, without moisture loss. Thus, Rubin perfectly does for surface, but at the same time steady stubble tillage at high working speed. The unit can be used at light-, mid- and heavy-textured soil.
Open construction of the frame with large free space provides undisturbed operation even with multitude of plant residues.
Serrated concave disks (620 mm diameter , 6 mm thickness) form the basis for the outstanding quality and long term work.
Thanks to optimal form of concave disks and large angle of attack, constant solid tillage is attained. When meeting any obstacle such as stones, discs can independently move up. That occurs due to considered construction of fastening of legs to the frame.
Disks` legs fastened by brackets are protected from overloads by firm springs and guarantee steady operation of disks even on heavy soil.
Springs serves for quick return of disks into the working position after overcoming an obstacle.
Good efficiency is achieved by high working speed up to 15 km/h provides intensive mixing of organic matter and soil.
It is possible to unitize the disk-harrow Rubin with air seeder “Solitair 9/600KA due to rigging device. Employment of disk-harrow “Rubin” permits to restore humus soil, lower costs for cropping and raise soil fertility.
