Abstract
A frame assembly for supporting an implement on a vehicle includes a support frame attachable to the vehicle, a lever pivotable about a first axis between first and second positions, and a biasing assembly connecting the lever to the support frame. A first end of the biasing assembly is supported against the lever to pivot about a second pivot axis being parallel to the first pivot axis and being vertically spaced relative to the first pivot axis when the support frame is removably attached to the vehicle and the lever is in the first position. A second end of the biasing assembly is supported against the support frame to pivot about a third pivot axis when the lever pivots about the first pivot axis. The third pivot axis is parallel to and is spaced from the first pivot axis when the support frame is removably attached to the vehicle.
