End spring legs are made of cast and are sealed with plate fins on both sides. Fertilizer and seed pass the hose between flaps and lays on the soil. Because resultant force forces the leg to come out of the soil due to wide penetration angle, sowing depth can be increased with additional loads. This feature shows superiority over other types of legs.  Good seed bed is prepared. Disc and spring-type chisel legs when faced with obstacles such as stone clod, tries to get up, but the axe is mounted to the chassis, leg movement does not come up. Should be replaced when axe is worn.
