This is a “RC 46” Rock Crusher, brand name is Keene Engineering, which is typically sold on a frame mount for $10k+ (without shipping) with the 11HP Honda motor. Now first off, this is a double functioning unit, meaning that it takes the 4”x6” rocks first down to a finer roughly ¾” mesh and then from there has a roller system that crushes it even finer (20 to 60 mesh). The roller unit is also adjustable if you want to have larger tailings. This is the tow behind unit, that works great and is fully functioning. I have run approximately 1 ton of material through it without any issues and is still in like new condition. I’m selling as my production level has upscaled significantly, where I just don’t use this unit for what it is intended for. Now I could uptalk this component about all the glorious things this has, but I feel it would be best for you to see for yourself its functions, ratings and what is being said about it online.

I live in the Boise area, and can either meet someone to look over the unit, or have the means to store this unit in the garage until next spring if arrangements need to be made.
