ABSTRACT:
A ditch hoe attachment has an attaching frame, an elongated arm, a scoop, and first and second actuators. The frame is attachable to a tractor-mounted front end loader and has a cross tube mounted for rotation about a first rotational axis and a crank lever attached to the cross tube for rotation therewith and extending radially therefrom. The elongated arm has a rear portion rigidly attached to the cross tube, and a front portion mounted to the rear portion for rotation relative thereto about a second rotational axis. The scoop is fixedly mounted to the outer end of the front portion of the elongated arm. The first actuator is mounted between the frame and crank arm and operable through forward and reverse strokes to rotate the cross tube and rear portion of the arm from forward to rearward positions and back to the forward position. The second actuator is mounted between the cross tube and front portion of the arm and operable through forward and reverse strokes to rotate the front portion relative to the rear portion of the arm from aligned to transverse positions and back to the aligned position. The first and second rotational axes are oriented transversely to one another such that successive operation of the first and second actuators through their forward and reverse strokes moves the scoop along a rearward loading path followed by a forward unloading path being laterally offset from the rearward loading path.
