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.

With over 50 years of experience W.H.O. has built into their grinders the features their customers needed and requested.

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.

If you need parts our friendly, knowledgeable staff can almost always guarantee same day shipping.
