  • Patent number: 5242177
    Abstract: An attachment for a wheelbarrow includes a load support member pivotally secured to a frame of the wheelbarrow at a front end thereof and adapted to facilitate lifting and supporting of heavy or bulky items for transportation. The load support member is pivotally advanceable between a raised position and a lowered position such that, when the load support member is positioned in the lowered position, the load support member extends in front of the wheel of the wheelbarrow. The load support member is advanceable to the raised position when not in use.

  • Patent number: 4850435
    Abstract: The convex upper surface of the generally triangular sweep has oppositely inclined, lateral faces that diverge from the forwardmost point of the sweep and serve to loosen and lift the soil while the outer cutting edges sever subsurface roots of weeds and other above-ground growth. Rigid, rearwardly extending flaps at the rear extremity of the sweep are disposed at such a strategic angle that although they rigidify the trailing section of the sweep and reduce wear which might otherwise occur at outer rear corners of the sweep, they avoid untoward turning and rolling of the loosened soil and severed plant materials so that moisture-retaining trash and plant residue is left intact on the ground surface.
