Abstract: An improvement that enhances hay rakes or forks of the type used in the cleaning of horse stables, includes a wall assembly having a rear wall and two spaced-apart side walls extending from the rear wall, that are positioned relative to a hay fork of conventional design so as to restrict unintended displacement of hay/manure mixtures over the peripheral edges of the hay fork. The bottom edge of the rear wall has a U-shaped indentation and includes a mounting flange of U-shaped cross section aligned with and extending from the indentation for straddling the handle of a conventional hay fork so that the wall assembly is retained and positioned properly relative to the fork portion of the hay fork. The rear wall and the side walls are formed with interlocking rails and slots so that the side walls may be readily attached to and detached from the rear wall by a sliding motion. An opening through the mounting flange receives a fastener to secure the wall assembly to the handle of a hay fork.

Abstract: A breakaway strap assembly for tethering a domestic animal such as a horse, employs two elongate straps separably attached by mating hook-and-loop surfaces. The mating hooks and loops resist longitudinal separation of the two straps. The hooks and loops are formed of resilient plastic material that permits them to unbend elastically so as to disengage from each other. Anchor clasps at one end of each strap allow the straps to be attached, respectively, to a fixed structure, such as a building and to a movable point such as the harness worn by a horse. The axial force resisting separation of the two straps can be varied from a low value to a relatively higher value by varying the longitudinal overlap of the two straps.
