npub18994crjwnldrukwym5lz3y2nae84s84v20m2rkngtjnyg549lr6qvxmd6m (npub1899…md6m) or the mount of the wheel axels has two opposing wedges so that as soon as the pulling starts the tractor frame is elevated on the sliding wedges and raises it only enough to clear the ground friction and possibly a small obstacle or so. Once the pulling stops, then some reasonable tension springs pull the wedges back so that the frame lowers and rests back.on the ground.
