Abstract: A hanger to hang an object to a support. The hanger includes an elongated base with a back, a mount that overlaps with a top section of the back, and a hook that overlaps with a bottom section of the back. A tongue is mounted to the back and extends outward from the back towards the hook. Apertures extend through the back, the tongue, and the mount, with the apertures aligned in a straight line. The base comprises a unitary, one-piece construction.

Abstract: A modular system for constructing an elevated pathway includes a first pathway segment comprising a first elevated platform portion; first edge supports to bare a load of the first elevated platform portion, wherein the first edge supports contact a ground surface and create a grade separation between the ground surface and a bottom side of the first elevated platform portion; and a first joint. The modular system also includes a second pathway segment comprising: a second elevated platform portion; second edge supports to bare a load of the second elevated platform portion, wherein the second edge supports contact the ground surface and create a grade separation between the ground surface and a bottom side of the second elevated platform portion; and a second joint to attach to the first joint to limit a motion of the second pathway segment relative to the first pathway segment.

Abstract: Apparatuses and methods are provided to facilitate the transport and storage of tilling machines and specifically mini-tillers. A wheel apparatus can attach to a tilling machine, such as by attachment to a drag bar, in a transport position or a storage position. In the transport position, the wheel apparatus can maintain tiller tines of the tilling machine above the ground surface with the weight of the tilling machine supported on the wheel apparatus, thereby allowing the tilling machine to be rolled for transport. In the storage position, the wheel apparatus can be attached to the drag bar, whereby both the tiller tines and the wheel apparatus rest on the ground surface to provide stability to the tilling machine. During operation the wheel apparatus can be removed from the tilling machine.
