Stalk bracket (612 8110) – is a unit that fastens the leg 412 8170 Lemken with hemispherical disk 349 0467 to the frame of the disk harrow.
Stalk brackets are protected from overloads by solid springs and guarantee steady operation of disks even on heavy soil.
Thanks to considered construction of legs fastening, with hemispherical disk to the frame of the disk harrow Rubin, legs are placed independently at tout spring elements of stalk brackets.
If compared with other methods of hanging of operating elements, it becomes clear that spring elements provide constant optimal pressure on disks, thus allowing long operation of the unit.
3298467 compression spring 14x97x202 is mounted at stalk bracket 612 8110
Solid compression springs provide constant working depth even on hard soils, that is significant advantage towards rubber dampers
Service life of compression springs is higher than of rubber dampers.
One more advantage of such fastening is good overload protection. Meeting an obstacle, such as stones, hemispherical discs 3490467 can climb independently. Compression springs serve also for quick returning of disks into working position.
