A sprocket damping assembly for a sprocket wheel of a track-type work machine may include an annular damping ring having an annular retention device. The damping ring may include a ring body section having a ring body section radial thickness, and a retention groove section integrally formed at an outboard side of the ring body section. The retention groove section may have a retention groove section axial width and a retention groove section radial thickness. The retention device may have a retention device axial width that is less than or equal to the retention groove section axial width. The retention device is disposed on the retention groove section when the damping ring is disposed on a sprocket drum outer surface of the sprocket wheel to retain the sprocket damping assembly. The retention groove section radial thickness may be less than the ring body section radial thickness.

A farm implement is provided having a frame and first and second track assemblies. The first track assembly has a first track frame, a first idler wheel, and a first brake assembly. The first idler wheel has an inboard side facing toward and an outboard side facing away from a center the first track frame. The first brake assembly has a first disc coupled to the first idler wheel on the outboard side of the first idler wheel, a first caliper couplable to first and second sides of the first disc, and a first torque arm coupled to the first track frame and a spindle of the first idler wheel. The first caliper is mounted on the first torque arm, and is configured to clamp down on the first and second sides of the first disc in order to slow and/or stop rotation of the first idler wheel.

A bushing for a track assembly, according to one or more embodiments, includes: a tubular bushing substrate having a longitudinal length and an outer surface; and at least one white iron member fixed to the outer surface of the tubular bushing substrate.

A support structure for a track system is disclosed. The support structure has leading and trailing linkages which are pivotally connectable to a frame member of the track system through, respectively, leading and trailing pivots. The leading linkage is pivotally connected to the trailing linkage through an intermediate pivot. The support structure has at least one biasing assembly. Leading, intermediate and trailing support wheel assemblies are connected to the support structure, which is adapted to move such that when the leading support wheel assembly moves in a first direction, the intermediate support wheel assembly moves in a second direction, and the trailing support wheel assembly moves in the first direction. A track system having the support structure and a vehicle having the track system is also disclosed.

A drive assembly for a mining vehicle includes a frame, a housing coupled to the frame, and a motor positioned in the housing. The motor includes a motor frame with a first axial end and a second axial end opposite the first axial end. The drive assembly also includes a transmission that is positioned at least partially within the frame. The transmission is coupled to the motor frame at the first axial end. The drive assembly further includes a support assembly that couples the second axial end of the motor frame to the housing.

A track chain assembly includes at least one track link having a shelf extending laterally from the a side surface and including a support surface spaced away from the top surface a predetermined distance measured perpendicularly to the top surface.
