Abstract:
1. A plow assembly for a vehicle, said plow assembly comprising: a center plow having first and second ends; a support for attaching said center plow to the vehicle, said center plow being pivotable relative to the vehicle between a first position, where said center plow is pivoted toward said first end, and a second position, where said center plow is pivoted toward said second end; a first plow wing on said first end of said center plow and a second plow wing on said second end of said center plow, each of said first and second plow wings being pivotable between an angled position, where said plow wing is angled forwardly with respect to said center plow, and an aligned position, where said plow wing is generally aligned with said center plow, said first and second plow wings being biased toward said angled positions via at least one biasing member; and a wing pivoting system for pivoting said first and second plow wings relative to said center plow, said wing pivoting system being operable to pivot said first plow wing to said aligned position in response to said center plow being pivoted to said first position and to pivot said second plow wing to said aligned position in response to said center plow being pivoted to said second position, said wing pivoting system comprising at least one connected member connected between said first and second plow wings and said support, said at least one connecting member being configured to move said first plow wing toward said aligned position as said center plow is pivoted toward said first position and to allow said first plow wing to move toward said angled position in response to said at least one biasing member as said center plow is pivoted away from said first position, said at least one connecting member being configured to move said second plow wing toward said aligned position as said center plow is pivoted toward said second position and to allow said second plow wing to move toward said angled position in response to said at least one biasing member as said center plow is pivoted away from said second position.
