摘要： A cutting tooth includes a tooth body having a mounting side, a front face spaced from the mounting side, and a plurality of lateral faces extending between the mounting side and the front face, the tooth body having an interior hardness, and a coating applied to at least one of the lateral faces to form a lateral hardface, the lateral hardface having a hardface hardness greater than the interior hardness, an edge of the lateral hardface closest to the front face and a portion of the front face adjacent the edge of the lateral hardface defining a cutting edge region of the tooth.

摘要： An active track-chain sag management system for usage in conjunction with crawler vehicles having tracked undercarriages includes a movable track-engaging member positioned for physical engagement into a track-chain of the tracked undercarriage, an electric drive assembly controllable to adjust a track-tensioning position of the movable track-engaging member relative to the track-chain, and a controller operatively coupled to the electric drive assembly. The controller is configured to command the electric drive assembly to repeatedly adjust the track-chain sag of the track-chain by varying the track-tensioning position of the movable track-engaging member during operation of the tracked undercarriage.

摘要： A work machine includes an undercarriage assembly. The undercarriage assembly includes a chassis and a ground-engaging mechanism for rotating around the chassis to move the work machine. A pair of rails is coupled to the chassis. A pair of sliders is coupled to a front-assembly. The sliders are aligned with the rails and movable relative to the rails to facilitate movement of the front-end assembly relative to the chassis.
