Abstract
A hydraulically-operated grapple attachment for the scoop bucket of a skid steer loader comprises a mounting bar running the length dimension of the bucket along a top rear edge thereof and pivotally attached to the mounting bar by tubular steel arms is a crossbar member having perpendicularly oriented tines projecting downward therefrom where at least one of the tines is hydraulically displaceable in a direction forward from the crossbar. Actuation of the hydraulically-movable tine serves to prevent the skid steer loader from becoming mired.
Claims9
An attachment adapted to be carried on hydraulically-activated arms of a skid steer loader work vehicle, comprising:
- (a) a grapple having a scoop bucket attachable to said hydraulically-actuated arms of a skid steer loader work vehicle, the scoop bucket having a generally rectangular bottom surface, a rear surface, an open top and sloping side surfaces extending from the rear surface to a front edge of the bottom surface, a crossbar pivotally hinged to an upper edge of the rear surface and supporting a plurality of perpendicularly extending teeth;
- a first hydraulic actuator operatively coupled between said upper edge of the rear surface of the scoop bucket and the crossbar for moving the plurality of teeth between an open position and a closed position relative to the front edge of the bottom surface;
- and
- (b) a second hydraulic actuator operatively coupled to one of the plurality of teeth for reciprocally displacing said one tooth forward of the crossbar.
A grapple attachment for a scoop bucket adapted to be coupled to hydraulic arms of a skid steer loader where the scoop bucket has an open top and open front, the grapple attachment comprising:
- a crossbar pivotally affixed to the scoop bucket, the crossbar supporting a plurality of parallel tines, and a first hydraulic actuator for pivoting the crossbar and tines between a raised state and a lowered state with respect to the open top and front of the scoop bucket, characterized in that at least one of the plurality of parallel tines being connected to a piston rod of a second hydraulic actuator which, when actuated, advances the one tine outward from the crossbar.
