Tub Grinder – PTO (Dry Clutch) Maintenance and Operation Tips
(Warning) improper adjustment of the mechanical PTO (clutch) can cause catastrophic failure of the PTO the first time you feed material to the grinder. Before operating the PTO on your tub grinder, be sure you’ve read and understand your manufacturer’s operations manual.

This is a brief introduction to tub grinders and some of the factors you should be considering when planning to purchase a new or used tub grinder.

Like cars, grinders depreciate rapidly in the first few years and many buyers realize too late that they have lost as much value on their new grinder as they made operating it. I believe that Grey Livingston said it best – “Driving a brand new car feels like driving around in an open billfold with the dollars flapping by your ears as they fly out the window.”
