A large cylindrical baler with a gauge for indicating the relative diameters of a bale being formed in the bale-forming chamber at two axially-spaced points on the bale periphery. The baler comprises a bale-forming chamber defined in part by a conveyor comprised of a plurality of endless loop belts. A belt-tensioning and take-up mechanism tensions all of the belts responsive to the diameter of the largest diameter portion of the bale during formation. The gauge has a pair of feelers engaging two of the belts in engagement with the periphery of the bale at two remote, axially-spaced points on the bale periphery. An indicator is positioned remotely of the bale-forming chamber and is interconnected with the pair of feelers through a signal transmitting means for transmitting a signal to the indicator responsive to the variation in tension of the two belts. The tension of the two belts is directly related to the relative diameters of the bale at the two points on the bale periphery engaged respectively by the two belts.
