Abstract

Perfections in cutting tines for rotary lawn mowers, of the type used in the cutter disk of a lawnmower having a radial receptacle separated inwards from the periphery, characterized in that each cutter is provided in combination, with a relatively thick body, finishing the body in its outer end in a relatively thin but not elastic tip portion extending outwardly from the periphery of the disc to provide a cutting edge, the body having a head at its lower end to retain the pus in the radial socket, being formed the cutting spike integrally made of durable plastic that has practically the characteristics of nylon, so that it protrudes from the periphery in a radially self-supporting position, with sufficient rigidity to cut the grass without having to lean on the centrifugal force when the disc rotates, being the conical construction plectrum, melting gently the portion the tip with the body so that, when hitting a fixed obstacle or weight, the tine yields bending back with a gently distributed curvature.
