W.H.O. invented the tub grinder and we've been building them since 1947. We've built them so rugged they have become the standard for waste reduction such as tree trimmings, industrial waste and general trash going into landfills.
In addition to building the best tub grinders possible. W.H.O. also offers their customers superior service. You can call the factory and talk directly to the people who built your grinder. They'll know what machine it is and any of it's special features.
