Abstract: A wear pad assembly for an implement of a machine is disclosed. The implement includes a forward face configured to engage and cast material sideways during a forward movement of the machine over a work surface, and a rearward face opposite the forward face. The wear pad assembly includes a first bracket, a second bracket, a wear pad, and a biasing member. The first bracket is configured to be fixedly coupled to the rearward face of the implement. The second bracket is pivotably coupled to the first bracket. The wear pad is coupled to the second bracket and is configured to contact the work surface. Further, the biasing member is engaged with the second bracket and is configured to bias the wear pad in abutment with the work surface during use of the implement.

Abstract: A motor grader including a frame and a scarifier system coupled to the frame. The scarifier system includes a first pin member and second pin member both coupled to the frame and interconnected to one another. The scarifier system also includes a first and second arcuate drawbar arms in spaced relation and coupled to the first pin member and a carriage. An actuator is coupled to the first arcuate drawbar arm and the second pin member to rotate the carriage about a pivot axis of the first pin member.

Abstract: A grading machine includes a machine body, a grading blade supported by a circle, a drawbar connecting the grading blade and the circle to the machine body, and a circle drive system. The circle drive system includes a circle drive motor and a gear box. The gear box is configured to engage with and rotate the circle relative to the drawbar around a circle axis. The circle drive motor includes an axis of rotation that is perpendicular to the circle axis, and the gear box includes an axis of rotation that is parallel to the circle axis.

Abstract: A work attachment for a motor grader includes a moldboard and a trip edge assembly coupled to the moldboard. The moldboard defines a plurality of first apertures. The trip edge assembly includes a trip edge structure. The trip edge assembly also includes a pivoting mechanism for pivoting a portion of the trip edge assembly in a first direction with respect to the moldboard when the trip edge assembly encounters an object in a drive path of the motor grader. The trip edge assembly further includes a mounting structure defining a plurality of second apertures. The plurality of second apertures are aligned with the plurality of first apertures to receive mechanical fasteners for removably coupling the trip edge assembly with the moldboard.

Abstract: A retention assembly, to slidably retain a blade to a support bracket of a grader machine, includes a yoke, a bearing arrangement, and one or more pins. The yoke is adapted to be coupled to the support bracket, and includes a first sidewall, a second sidewall, and a cavity defined therebetween. The first sidewall defines a first thickness and one or more first bores. The second sidewall defines a second thickness and one or more second bores. The second bores are correspondingly co-axial to the first bores. The bearing arrangement is received within the cavity and is adapted to support the blade for a sliding movement of the blade relative to the bearing arrangement. Further, the pins extend correspondingly through at least one of the first bores or the second bores, and into the cavity to engage and retain the bearing arrangement within the cavity.
