ABSTRACT:
A cultivating tool assembly for attachment to the tool bar of a cultivator frame utilizes an upright bracket for connection to the tool bar and an arm member pivotally connected to the mounting bracket and extending substantially horizontally therebehind. A coil spring biasing arrangement is also pivotally connected to the mounting bracket and extends in parallel relation to the arm member, connecting to a cradle forming a leverage arm extending upwardly from an outer end of the arm member. A tool shank having an elongate, generally horizontally extending upper end is affixed to the arm member and curves outwardly and downwardly in a semi-circular arrangement, culminating at a tool tip. The biasing arrangement is adjustable to vary the amount of force applied by the coil spring between the mounting bracket and cradle to control the running depth of the tool and to set the trip pressure.
