1. A support apparatus for securing a material moving wing plow relative to a vehicle, said support apparatus comprising:

  • a beam having a first and a second end, said beam being rigidly secured to the vehicle;

    a plate having a first and a second extremity, said plate being rigidly secured to said beam;

    a first trailing link pivotally secured to said plate about a first pivotal axis;

    a second trailing link pivotally secured to said plate about a second pivotal axis;

    a support arm for supporting the wing plow, said support arm having a first termination and a second termination, said support arm being pivotally secured to said first trailing link about a third pivotal axis, said support arm being secured to said second trailing link so that during a plowing operation, the wing plow supported by said support arm moves smoothly over the material being moved so that a potentially dangerous diving of the wing plow into the material in a vicinity of said support arm is avoided;

    said support arm being pivotally secured to said second trailing link;

    said support arm being pivotally secured to said second trailing link about a fourth pivotal axis, said first, second, third and fourth pivotal axes being spaced and parallel relative to each other so that when the vehicle moves in a forward direction, said third and fourth pivotal axes trail behind said first and second pivotal axes relative to said forward direction of the vehicle;

    a further plate having a further first and a further second extremity, said further plate being rigidly secured to said beam between said plate and said first end of said beam;

    a further first trailing link pivotally secured to said further plate about said first pivotal axis;

    a further second trailing link pivotally secured to said further plate about said second pivotal axis; and

    an arm having a further first termination and a further second termination, said arm being pivotally secured to said further first trailing link about said third pivotal axis, said arm being pivotally secured to said further second trailing link about said fourth pivotal axis.
