  • Patent number: 4548543
    Abstract: A quick attachment device (12) for releasably connecting an implement (10) such as a loader to a vehicle without special tools comprises a pair of uprights (26) connected to the implement and a pair of corresponding pedestals (32) mounted on opposite sides of the vehicle. Each upright (26) is cradled by trunnions (40) in notches (38) on the corresponding pedestal (32) and releasably secured thereto by means of locking pins (48).
