ABSTRACT:
An earthworking tool having a biased trip assembly for yieldably holding the tool in a ground working position, allowing the tool to move over an obstacle, and return the tool to its earthworking position. The trip assembly has a stationary hinge member mounted to a support and a movable hinge member pivoted to the stationary member. A split sleeve spring surrounding the stationary and movable hinge members biases the members and earthworking tool to a ground working position. A modified trip assembly has a pair of split ring springs surrounding a stationary hinge member and movable hinge member to bias the movable member and earthworking tool attached thereto to a ground working position. An arm connected to the movable member rotatably supports a rotary hoe wheel.
