Why not a small PTO rock crusher?

MiserableOldFart · May 24, 2022

I think it's in the film, "O brother, where are thou?" an old tractor is operating a small drop-in rock crusher with its belt. I see online that if you have a 100+hp tractor, you can buy, at enormous cost, a much larger PTO rock crusher or a field rock crusher that crushes rocks in a field, but all the smaller units are really, really small and cater to prospectors, and are mostly small engine or electrically operated.
It would be great to have a PTO jaw type rock crusher that could break medium sized shale stones like we have here in the Catskills by the milions, but there doesn't seem to such an animal..It would probably have be operated by its own hydraulics like some of the wood chippers are, for safety, but it would seem to be something that could be made fairly inexpensively.. I've seen some home made units in Youtube videos..

I agree, it seems like a great machine for folks wanting to crush their own rock for a driveway.

Edit: Get the little rocks you want and rid of the big rocks you don't!
Kill two rocks with one stone? No, wait. I'll see myself out now

I seem to just use my rotary cutter for that

Would be nice, but so would a picker at a LOW cost.

I don't know. All I have here is basaltic lava - one of the harder rock forms known. I think a low cost picker might be an easier choice.

They are out there, but they are expensive both to buy and maintain.
And even the small ones need a considerable amount of horsepower.
Even the lightest ones with a 42" working width need 80 to 100 Hp and a CVT transmission.

There's no practical crusher for personal use. Even a rake/picker that works is an expensive tool unless one owns alot of land.

Look up mbmmllc on YouTube. The guy builds all sizes of jaw crushers for mining and recycling uses. Email him and I'm sure he could put a PTO shaft on one of them.

So, I just ordered a 8" x 12" jaw crusher from MBMM. They said they are working on a PTO crusher. I would think for us tractor guys a PTO crusher would be great. I'd have bought one.

If it were run off a PTO, it would make quick work of your PTO clutches, or worse….
