Abstract: A mounting assembly for a blade of a motor grader includes a mounting bracket having a mounting channel. The mounting assembly includes an adjustment block disposed in the mounting channel. The adjustment block includes a mounting groove and at least one slot disposed spaced apart with respect to the mounting groove. The mounting assembly also includes at least one retention plate disposed on the mounting bracket. The at least one retention plate is adapted to engage with the at least one slot provided on the adjustment block. The at least one retention plate is adapted to limit movement of the adjustment block along a longitudinal axis of the adjustment block. The mounting assembly further includes a wear element disposed in the mounting groove provided in the adjustment block. The wear element is adapted to slidably receive a portion of the blade thereon.

Abstract: A system for operating a circle drive gear of a machine includes a pump configured to output pressurized fluid, an implement control valve fluidly coupled to the pump, a bi-directional hydraulic motor located downstream of the implement control valve and fluidly coupled to the implement control valve via a first delivery line and a second delivery line. The hydraulic motor has an output shaft that is configured to be rotatively driven by pressurized fluid output by the pump. A brake is disposed on the output shaft of the hydraulic motor and engages with the output shaft with the help of a spring force for reducing a rotational speed of the output shaft in a brake engage state. The brake operatively disengages from the output shaft in a brake release state with the help of fluid pressure in at least one of the first delivery line and the second delivery line.

Abstract: A rear frame for a motor grader includes a pair of arms that are disposed equidistantly from a mid-plane. Each arm has a front portion, a rear portion, and a mid-portion located between the front and rear portions. The front portion of each arm is configured to pivotally couple with a front frame of the motor grader. The rear frame also includes a ripper mounting arrangement, a bumper, and a torque resisting member. The ripper mounting arrangement is located at a rear end of the rear portion of each arm. The bumper is laterally disposed with respect to the mid-plane and rigidly attached to a position on the rear portion of each arm located adjacent the rear end of the rear portion of each arm. The torque resisting member is laterally disposed with respect to the mid-plane and rigidly attached to the mid-portion of each arm.

Abstract: A sealing assembly for a circle member of a motor grader is provided. The sealing assembly includes a plurality of cover segments disposed adjacent to an inner circumference of the circle member. At least one of the plurality of cover segments defines a gap in association with a component disposed adjacent to the at least one of the plurality of cover segments. The sealing assembly also includes a sealing element removably disposed on the at least one of the plurality of cover segments and extending into the gap. The sealing element is adapted to sealingly engage each of the at least one of the plurality of cover segments and the component.

Abstract: 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.
