An improvement that enhances the functioning and efficiency of hay rakes or hay forks of the type used in the cleaning of horse stables and the like, includes a wall assembly having a rear wall element and two spaced-apart side wall elements extending fro m the rear wall element, that are positioned relative to a hay fork of conventional de sign so as to restrict unintended transverse displacement of hay/manure mixtures over the r ear and lateral peripheral edges of the hay fork. The bottom edge of the rear wall eleme nt has a U-shaped indentation formed therein and further includes a mounting flange of Ushaped cross section aligned with and extending from the indentation for straddl ing the handle of a conventional hay fork so that the wall assembly is retained and posi tioned properly relative to the fork portion of the hay fork The rear wall element and the side wall elements are formed with interlocking rails and slots so that the side wall elements may be readily attached to and detached from the rear wall element by a sliding motion. An opening through the mounting flange receives a fastener to secure the wall as sembly 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 attac hment to an existing fork structure, or it may be integral with the fork structure.
