Abstract: A dirt gathering and hauling bucket is pivotally attached to manually operable lift arms mounted to extend rearwardly on the back end of a riding garden tractor to swing level with open top and front, and a leading sharp edge defined forwardly by a closed bottom. A pair of transverse elements, vertically spaced apart, are mounted adjacent the forward upper edge of the bucket to loosely receive therethrough the free end of a jam bar that is pivoted by its other end to the rear of the garden tractor between the lift arms. The difference between the vertical dimension of the jam bar and the vertical space between transverse elements determines the angle of tilt of the bucket and its leading sharp edge as it engages the ground, when lowered by the lift arms, by the jam bar jamming between the transverse elements to stop the bucket's rearward pivoting.
