METHOD AND APPARATUS FOR MAINTAINING LEVEL PLOW WHEN ANGLING

摘要

A support assembly that includes first and second frame components may be used to support a plow blade to a vehicle. The first frame component may have a first end defining a first pivot axis about which the plow blade pivots when it is moved side-to-side. The second frame component may have a first end that defines a second pivot axis about which the second frame component, the first frame component and the plow blade pivot when the plow blade is raised or lowered. A second end of the first frame component may be pivotally attached to a second end of the second frame component about a third pivot axis. The first frame component and the plow blade may automatically pivot together about the third pivot axis to maintain the plow blade in a level orientation even when the plow blade is both raised and moved side-to-side.
