Abstract

A work machine, such as a tractor or skid steer, has a motion sensor attached to a segment of a continuous ground-engaging track in its undercarriage. The motion sensor generates motion data indicative of a change in motion for the track segment as the track rotates around a track assembly. An electronic controller for the work machine receives and evaluates the motion data, first to identify a location of the track segment within the undercarriage and then to compare the motion data with expected motion data for the track segment under normal track tension. Motion data outside a range of the expected motion data indicates an abnormal sag in the track, causing the electronic controller to generate an alert for adjustment of the track tension.
