A hay bale dryer features a support frame inside of which there is delimitedat leastone bale space and at least one manifold carrying a set of aeration spearsmovablebetween a deployed position penetrating the bale space and a retractedpositionwithdrawn therefrom. The manifold is moved between the positions by way of anactuator driven linkage, and the aeration spears comprise hollow elongatedbodies oftapered thickness toward their distal ends for more effective penetration ofthe haybales. A manufacturing method uses a hydraulic press to produce the hollowelongated bodies from lengths of originally cylindrically pipe. Horizontalfeedingtables and upright feeding racks feature displaceable bale movers for movingqueuedhay bales along one or more queuing lanes into one or more bale dryers.
