Abstract

A ground leveler attachment for a ground working device comprises a bracket fastened to a shank supporting a ground breaking tool, a carrier arm connected to the bracket, a pair of leg supports in pivotal contact with the carrier arm, a pair of springs biasing the legs supports into pivotal contact with the carrier arm, a pair of leg members extending from the leg supports, and a pair of levelers rotatably mounted upon the leg members and biased into a ground engagement position by the springs. The levelers independently and resiliently retract upon contact with a relatively immoveable object or objects to avoid being broken off from the leg members or severely damaged beyond usefulness.
