Abstract: A snow removal apparatus and related method for removing snow from an underlying surface. The apparatus includes a plow blade arranged to stand off from the underlying surface when the apparatus is in use, a first air transport unit for delivering forced air into an air blade plenum and a second air transport unit for delivering forced air to a Venturi vacuum jet. The air blade plenum is arranged to deliver air to the underlying surface to lift snow located thereon. The Venturi vacuum jet is arranged to push air and lifted snow into and through a collection chute. Use of the apparatus results in a cleaner roadway that results per pass at a higher speed with less need for the use of salt and/or sand and substantially less wear and tear on the roadway.

Abstract: A method for detecting wear in an implement system of a grading machine includes receiving acceleration information from a sensor connected to the implement system while the grading machine performs a task and estimating an incremental amount of wear in the implement system of the grading machine based on the acceleration information. The method also includes determining a cumulative amount of wear in the implement system of the grading machine and outputting a notification based on the cumulative amount of wear.
