A track saw, comprising: a motor including a motor shaft configured to rotate about a shaft rotational axis; an arbor configured to attach a circular saw blade to the track saw and to receive a torque from the motor when the motor shaft rotates about the shaft rotational axis; a base plate that defines an arbor-facing side and an arbor-opposed side, wherein the arbor-facing side of the base plate faces toward the arbor, wherein the base plate includes: (i) a rib-receiving channel defined on the arbor-opposed side of the base plate and configured to receive a raised elongate rib of a track; and (ii) a self-adjusting rib-guide assembly that at least partially defines the rib-receiving channel, wherein the self-adjusting rib-guide assembly is configured to automatically adjust for a range of raised rib transverse widths, wherein the self-adjusting rib-guide assembly includes a roller shaft, a guide roller, and a biasing mechanism, wherein the guide roller is configured to operatively rotate about the roller shaft, characterized in that the guide roller is configured to operatively translate along the roller shaft between an extended state, which defines a minimum transverse width of a region of the rib-receiving channel that is at least partially defined by the self-adjusting rib-guide assembly, and a retracted state, which defines a maximum transverse width of the region of the rib-receiving channel that is at least partially defined by the self-adjusting rib-guide assembly. a motor including a motor shaft configured to rotate about a shaft rotational axis; an arbor configured to attach a circular saw blade to the track saw and to receive a torque from the motor when the motor shaft rotates about the shaft rotational axis; a base plate that defines an arbor-facing side and an arbor-opposed side, wherein the arbor-facing side of the base plate faces toward the arbor, wherein the base plate includes: (i) a rib-receiving channel defined on the arbor-opposed side of the base plate and configured to receive a raised elongate rib of a track; and (ii) a self-adjusting rib-guide assembly that at least partially defines the rib-receiving channel, wherein the self-adjusting rib-guide assembly is configured to automatically adjust for a range of raised rib transverse widths, (i) a rib-receiving channel defined on the arbor-opposed side of the base plate and configured to receive a raised elongate rib of a track; and (ii) a self-adjusting rib-guide assembly that at least partially defines the rib-receiving channel, wherein the self-adjusting rib-guide assembly is configured to automatically adjust for a range of raised rib transverse widths, wherein the self-adjusting rib-guide assembly includes a roller shaft, a guide roller, and a biasing mechanism, wherein the guide roller is configured to operatively rotate about the roller shaft, characterized in that the guide roller is configured to operatively translate along the roller shaft between an extended state, which defines a minimum transverse width of a region of the rib-receiving channel that is at least partially defined by the self-adjusting rib-guide assembly, and a retracted state, which defines a maximum transverse width of the region of the rib-receiving channel that is at least partially defined by the self-adjusting rib-guide assembly.
