Abstract: Auxiliary structural bumpers are adapted to be attached to a main protective bumper assembly for a refrigeration unit of the type adapted to be mounted on the front wall of a trailer. The main protective bumper protects the front of the unit while the auxiliary bumpers are adapted to protect the left and right-hand sides of the refrigeration unit. The refrigeration unit includes an outer cover, and a structural framework, which includes a pair of vertically extending structural elements located at opposite rear corners of the refrigeration unit adjacent to the front wall of the trailer. The main bumper assembly includes two vertically extending structural members, each of which is adapted to be structurally coupled to one of the vertically extending structural elements of the refrigeration unit.

The refrigeration unit includes an outer cover, and a structural framework which includes a pair of vertically extending structural elements located at opposite rear corners of the refrigeration unit adjacent to the front wall of the trailer. The bumper assembly includes two vertically extending structural members, each of which is adapted to be structurally coupled to one of the vertically extending structural elements of the refrigeration unit. A portion of the vertically extending structural member extends above the outer cover of the unit. A pair of horizontally extending structural members also located outside the outer cover of the refrigeration unit are attached to the ends of the vertically extending members at one end thereof and the other ends extend forwardly towards the front of the refrigeration unit.

Abstract: A brush for grooming golf greens and fairways. Three identical brush devices are removably connected together with two of the brush devices located laterally outward of the middle brush device. When not in use and in transport, the three brush units may be aligned in single file for towing along a narrow path. Each brush device includes a plurality of depending brushes removably mounted to a rectangular frame. The brushes are arranged to assure even grass grooming and even brush wear. A winch with cable is mounted to the frame and is operable to raise and lower wheels to support the brush device when not in use.
