A tracked running gear includes a drive sprocket having two sides and laterally projecting tooth profiles on both sides; a guide wheel, at least one track roller, at least one support roller, and an endless chain formed by ground plates interconnected in an articulated manner. The ground plates have vertically extending parallel teeth which engage the tooth profiles on both sides of the drive sprocket as the ground plates are diverted around the drive sprocket. The ground plates also include a first running surface having a substantially rectilinear form between the teeth for engaging the track roller and support roller, and second running surfaces having a curved form and arranged on opposite sides of the first running surface and between the teeth for engagement with the guide wheel and the drive sprocket.
