Abstract

See full text

In some implementations a lift assembly for a snow wing assembly may include a first lifting mechanism, coupled to the motor grader, configured to lift the snow wing assembly a first portion of a bench height associated with a moldboard via a first hydraulic cylinder. The lift assembly may include a second lifting mechanism, coupled to the first lifting mechanism and the moldboard, configured to lift the moldboard of the snow wing assembly a second portion of the bench height via a second hydraulic cylinder. The lift assembly may include one or more valves included in a hydraulic circuit of the first hydraulic cylinder and the second hydraulic cylinder, configured to divert a flow of hydraulic fluid in the hydraulic circuit away from a first stage hydraulic cylinder and to a second stage hydraulic cylinder, based on a pressure value associated with the first stage hydraulic cylinder.
