ABSTRACT:
A lifting aid for lifting and supporting a ground engagement tool has an L-shaped cradle having a longitudinally extending base and back wall. A lifting yoke having at least two tubular arms is slideably connected to the L-shaped cradle through tubular sleeves which extend upward to a lifting point. The tubular arms have an upper portion, and a lower portion angled relative to the upper portion, for forming an inflection point inclined rearward toward the back wall. In a rest position, the inflection point is positioned adjacent the tubular sleeves leaving space for the tool. In a lifted position, the inflection point approaches the back wall for gripping the tool therebetween.
