  • Patent number: 4612716
    Abstract: A small trolley-mounted hand-propelled home or professional digger is disclosed, or a `mini-digger`, comprising a power pack carried by the trolley and an earth-moving hinged boom assembly with scoop mounted to the front of the trolley, the trolley itself being provided with handlebars and with a pair of wheels or tracks for propulsion purposes, as well as with two front stabilizers and a rear footboard on which the user stands during digging operations. The hinged boom comprises a main stage and a tilt stage which can be folded together parallel and vertical, almost touching, so as to remain compact and balance the weight of the power pack when the `mini-digger` is in transit, and can be swung about a vertical axis.
