A slider includes a first segment and a second segment. The first segment includes a first upper surface, a first lower surface, and a first interior surface that connects the first upper surface to the first lower surface. The first upper surface is configured to support a track. The first interior surface includes a first component of an attachment mechanism. The second segment includes a second upper surface, a second lower surface, and a second interior surface that connects the second upper surface to the second lower surface. The second upper surface is configured to support the track. The second interior surface includes a second component of the attachment mechanism that is configured to be removably attached to the first component.

A replaceable guide rail for a crawler includes a base that has a flange. The replaceable guide rail further includes a hole extending laterally through the flange that is configured to receive a fastener to secure a portion of the crawler to the flange, a guide member extending along the centerline and being configured to contact a track portion of the crawler and be worn down during movement of the track portion over the guide member, and a wear indicator positioned in the guide member configured to indicate whether the guide rail is in condition for replacement. The guide member has a thickness that is reduced as the guide member is worn down. The wear indicator is covered while the thickness is in a first range of thickness, and the wear indicator is exposed while the thickness is in a second range of thickness.

The present technology generally relates to multi-feature track systems exhibiting enhanced performance, vehicles having track systems, rear track system configurations, support structures for track systems, tensioners for track systems, wheels and wheel assemblies for track systems, seal assemblies, protective cover assemblies, mounting attachments for track systems and endless tracks for track systems.

A machine comprises a frame, a plurality of ground engaging units, a plurality of moveable legs, and a hydraulic system. A first ground engaging unit and a second ground engaging unit connect a first leg and a second leg, respectively, with the frame. The hydraulic system controls heights of the plurality of moveable legs. The hydraulic system comprises a fluid circuit to control fluid between the first and second legs, a load holding valve to control fluid flow into the fluid circuit, and first and second relief valves to control flow of fluid between the first and second legs in opposite directions. A method for controlling slope of a construction machine comprises activating a relief valve connecting right and left lifting cylinders to control flow of hydraulic fluid between the lifting cylinders to control retraction of one of the lifting cylinders from retracting.

An endless track assembly that mounts to a vehicle drive linkage. The track assembly includes a belted track, drive sprocket and sets of longitudinally and laterally offset ramp/road and idler/road wheels mounted to parallel sets of vertically offset coplanar axles that support interior track surfaces. Axles mounted adjacent forwardmost and aftmost ramp/road wheels support “anti-jam” wheels that are longitudinally and vertically offset from the other axles at the framework to prevent a kinking of the track at the forwardmost and aftmost ends.

A track assembly for assisting in moving a farm implement along a ground surface in a line of travel is provided. The track assembly includes a tilt arm comprising front and rear ends. The track assembly includes a camber arm coupled to the tilt arm such that the camber arm permits the tilt arm to pivot about a first axis perpendicular to the line of travel and a second axis parallel to the line of travel. The camber arm is located between the front and rear ends of the tilt arm.
