This Portable Rotary Composter is designed to turn crop, livestock, and other agricultural-produced residues into compost in as few as 6 days. To use, the residue materials are first shredded in a feed hopper then conveyed into the Composter, which, via continuous forced-air induction and rotation, creates an end product that's reportedly free of pathogens, weed seeds, and parasites. Features include: tiltable (down for unloading, up for filling), programmable, fully aerated, swivel-jack levelers, safety devices (warning light/sound/brake/emergency shut-off), and optional power sources (AC/DC/solar/wind). Available in four models with 1.5-, 7.5-, 15- and 22.5-cubic-yard capacities.
