Abstract
An apparatus and a method for removing snow from a travel surface, including a wear member movably connected to a main blade or wing blade. In some embodiments, a fastener connected to the wear member extends through an aperture in the blade and is biased in a downward direction by a biasing mechanism connected to the blade. The biasing mechanism can include a spring, brackets retaining the spring in position with respect to the blade, and a shaft connected to the fastener and to the spring to exert a biasing force (e.g., a downward force) upon the fastener and therefore upon the wear member. The wear member can pivot about a pivot point while the biasing member biases the wear member against the travel surface.
