You betcha Mike, a big rock crusher!
...it will break rock, needs a 3/4hp electric motor & I have one that use to run my 21 foot conveyor that I had in the basement nearly a decade ago... geez time flies!
Ken, the maker/seller told me to get a new pulley & he'd reimburse me the cost... the pulley is on a browning hub, I'm pretty sure I can find another like it in town.
