Abstract: A walk-behind working machine has a machine body and a wheel mounted on the machine body for undergoing rotation to move the walk-behind working machine along a ground surface. A cultivator device is mounted on the machine body for cultivating the ground. A working device attachment is removably connected to the machine body for working the ground. A connection mechanism removably connects the working device attachment to the machine body. The connection mechanism has a pair of link members each pivotally connected at a first end portion thereof to the working device attachment and a control unit for controlling a position of the working device attachment with respect to the ground surface so that when the working operation, the first end portions of the link members are disposed closer to the ground surface than the second end portions of the link members.

Abstract: A beach combing apparatus is set forth wherein a plurality of spaced runners have secured therebetween an elongate blade member formed with a forwardly positioned beveled planar blade formed with a spaced parallel rear overfolded edge to provide strength and integrity to said blade. A plurality of spaced parallel upstanding brackets integrally formed to said blade to secure an elongate "U" shaped handle is mounted between the brackets at terminal end portions integrally formed to said handle at an obtuse angle thereto whereupon said handle is oriented relative to said blade member at an angle of approximately 30 to 45 degrees in a first position and pivotal parallel to said blade member in a second position to effect the cutting and trimming of various growth to be found growing on a beach surface.
