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. A resilient latch near the forward end of each side wall is capable of engaging a tine of a hay fork to further secure the wall assembly to the fork. The wall assembly may be provided entirely independently of a hay fork for attachment to an existing fork structure, or it may be integral with the fork structure.
