Abstract
An implement for levelling the surface of an agricultural field, a so-called furrow-smoother, comprises a plurality of rings of rotary knives to throw the surface earth laterally away from the higher areas. The rings of knives are journalled in bearings which are suspended from a carrier frame by means of arms that extend below the bearings and substantially tangentially therefrom so as not to catch plant remains (straw, stem, and root material) carried along by the two knife rings sweeping on either side of the bearing arm.
