  • Patent number: 5373902
    Abstract: A hood assembly includes a hood member and an adjustable length stabilizing link. The stabilizing link is movable between a first position at which the link maintains a bottom surface of the hood member in a substantially parallel relationship with a ground, or soil, surface and a second position at which the link tilts, or rotates, the hood member and thereby moves the bottom surface of the hood member to a nonparallel orientation with the ground surface. When in the tilted position, a portion of the bottom surface of the hood member is spaced from the ground surface at a distance sufficient to permit access for the repair or service of elements normally protectively enclosed by the hood member.
