Tub grinders
WHO replacement parts
WHO (W.H.O. Manufacturing) tub grinders. AGS supplies wear parts — we do not manufacture WHO machines. Call with the model. No public part numbers.

- Model
- Serial number, if you have it
- A photo of the worn part
- What is worn: screen, hammers, tips, chain, or belting
Manufacturer names identify the machine, not a partnership. Fit is confirmed on the call.
Screens, hammers, carbide tips, cutterbars, wear plates, hardware, chain, and belting — as they apply to this mill. No cart. No public prices.
