A crawler with a wear limit indicator comprises a crawler main body, sprocket holes formed to pass through a central portion of the crawler main body at equal intervals, core metals configured to be inserted and installed in-between the sprocket holes, left lugs configured to protrude from one surface of the crawler main body and simultaneously overlap with the sprocket holes and one of the core metals, right lugs configured to protrude from the other surface of the crawler main body and simultaneously overlap a pair of adjacent core metals, and a wear limit indicator configured to protrude from front and rear surfaces of the left lugs and the right lugs and inform that a replacement time for a crawler has come when worn-out surfaces of the left lugs and the right lugs are placed on the same horizontal plane as the wear limit indicator.

A track chain assembly includes a first track pad including a first pair of lugs defining a gap therebetween, and a second track pad including an intermediate lug disposed in the gap. The first pair of lugs and the intermediate lug each define a concentric bore, defining an axis of rotation for a pinned joint of the track chain assembly, and the concentric bore of one of the first pair of lugs is in communication with the gap with a first blend disposed axially between the gap and the concentric bore.

A final drive seal guard for a track-type tractor including a base component adapted to be stationarily fixed to the tractor and to surround a portion of a spindle housing of the final drive, a sprocket component adapted to be carried on and surround a portion of a sprocket hub of the final drive that rotates about an axis, and an intermediate component adapted to be bolted over the exterior of one of said base and sprocket components and surround portions of both of said base and sprocket components, the intermediate component and another of said base or sprocket components being mutually arranged to form a radially extending sealing gap at a potential path of debris into the guard at a location free of a relatively long axial gap upstream in said potential path.

A track roller shaft comprises a body including a revolved surface defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation. The body also defines a proximate axial end disposed along the axis of rotation, a radially extending hole that is disposed axially adjacent to the proximate axial end, and a guide member receiving pocket disposed axially further away from the proximate axial end than the radially extending hole.

A wheel of a track system for traction of a vehicle (e.g., an agricultural vehicle) may be configured to protect against (e.g., prevent) accumulation of unwanted ground matter, such as mud, debris, water, etc., within the wheel, while enhancing visual appearance of the wheel. This may help to avoid or minimize mud buildup that may otherwise need to be drilled out before removing the wheel (e.g., for replacement or maintenance) and/or rust that may otherwise arise.

A soil disbursement system is provided. An undercarriage soil disbursement system for a heavy equipment vehicle including a vehicle body and an undercarriage including a track, comprising one or more conveyors configured to be mounted within the undercarriage for collecting debris from the tracks and discharging the debris out a side of the undercarriage, a drive for actuating the one or more conveyors and one or more sweeping blades configured to be mounted on an underside of the vehicle body, whereby during rotation of the vehicle body the sweeping blades push debris from the track onto the one or more conveyors.

A track hinge joint includes a first track link, a second track link, a track pin disposed in a bore of the first track link, an inner bushing that is disposed in a bore of the second track link and that is rotatable relative to the track pin, an outer bushing that is disposed about the inner bushing that is rotatable relative to the inner bushing and that includes an outer bushing end face, and a first fluid seal assembly contacting the outer bushing end face and the second track link.
