Abstract
Abstract A tool holder having an upright standard and converging side arms connected to a horizontal plate. A clamp holds the standard on a tool bar. A pair of identical connectors mounted on the side arms carry brackets adapted to support earth working tools, as knives or discs. The connector has an upright passageway for the bracket. Transverse and longitudinal clamping bolts hold the bracket on the connector. One side of the connector has a longitudinal horizontal dovetail groove accommodating an arm. The groove extends at an angle to the longitudinal plane of the passageway. A clamping bolt holds the connector in fixed relation on the arm. The connector is reversible on either arm and is used to change the angular relationship between the arm and bracket.
