ABSTRACT:
A relatively compact and lightweight planting and fertilizing apparatus is attached to a small garden tractor by a universal hitch which restricts lateral movement between the two. The apparatus is spring biased downwardly to assure firm contact with the ground, and can be raised above the ground by a single lever. The lever carries the biasing spring, and cams lifting bearings on the lever against a lifting plate on the apparatus. The fertilizer is fed by an axially adjustable feed gear rotated by a ground engaging wheel on the apparatus. The feed gear is biased by an adjusting spring against a threaded adjusting knob which sets the axial position of the feed gear.
