A controller may receive, from a sensor device of a machine, machine drivetrain data indicating a load, on a drivetrain of the machine, over a period of time. The controller may detect, based on the machine drivetrain data, one or more occurrences of a decrease in the load during the period of time. The controller may determine that the one or more occurrences, of the decrease in the load, are unexpected. The controller may detect wear of a component of an undercarriage of the machine based on determining that the one or more occurrences, of the decrease in the load, are unexpected. The controller may cause an action to be performed based on determining the wear of the component.

A steel for a tracked undercarriage component is used as a material constituting a track link (9), for example, and contains: not less than 0.39% by mass and not more than 0.45% by mass of carbon, not less than 0.2% by mass and not more than 1.0% by mass of silicon, not less than 0.10% by mass and not more than 0.90% by mass of manganese, not less than 0.002% by mass and not more than 0.005% by mass of sulfur, not less than 0.1% by mass and not more than 3.0% by mass of nickel, not less than 0.70% by mass and not more than 1.50% by mass of chromium, and not less than 0.10% by mass and not more than 0.60% by mass of molybdenum, with the balance made of iron and unavoidable impurities.

A vehicle comprises a chassis, a seat, an endless drive track, a rear suspension assembly with at least one slide rail and a substantially inextensible limiter strap extending between the chassis and the at least one slide rail, to limit separation between the at least one slide rail and the chassis. The strap holder is moveable between a first holder position and a second holder position, a position of the end of the limiter strap being different in the first strap holder position compared to the second strap holder position. A control cable is operatively connects the strap holder to a strap adjustment actuator. The strap adjustment actuator is disposed forward of the seat and is operable by a user during operation of the vehicle, the strap adjustment actuator being movable between first and second positions related to the positions of the strap holder.

A system and method for compensating reduced track speed because of engine droop for a work machine is disclosed. The system may comprise a frame, an attachment coupled to the frame, a ground-engaging mechanism adapted to support the frame, an engine, a motor, a track speed sensor, an engine speed sensor, and a controller. The engine may drive the ground-engaging mechanism and attachment. The engine may be coupled through a variable speed transmission to the ground-engaging mechanism and the attachment. They variable speed transmission may include a hydrostatic circuit. The controller may be adapted to send an increased transmission command signal based on a drop in the engine speed signal when the work machine engages an increased load. The increased transmission command signal may increase a motor speed to cause an increase in track speed to compensate at least a portion of the reduced track speed from the engine speed droop.
