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.
