I Know this has been covered several times, but this is my version.
I live in a no-burn community, I have an old (5 HP) Roto-Hoe chipper/shredder that came very cheap from a rummage sale, I have an ancient Kubota B7100 with a three speed PTO.
I got really tired of coaxing the ancient Roto-Hoe into life the two or three times a year I wanted to tidy up the property. If it wasn't hard starting, it was a flat tire, or some other picky thing, the list goes on. After checking all the details such as direction of rotation, shaft sizes, condition of the working parts of the shredder, formulating a general design concept, I tore into the project.
The bottom line, it works like a charm. The top PTO speed of the B7100 is listed at 1000 RPM but I assume that is at a higher engine speed. With the tractor engine at idle speed, during initial testing, the shredder works just fine for the typical annual prunings and yard waste to be converted into mulch.
Final thoughts; it took a couple of days and lots of fiddling to get this done. If I wasn't retired and only had limited time to work on such a project, it might be a tossup. There are a number of places to recycle yard waste nearby. However it is nice to have a way to easily shred/chip usable mulch for the yard, the tractor runs MUCH quieter than that 5HP Briggs, the shredder is way easier to move around, with the wheels and Briggs gone it is much more compact and easier to store, and last, there is little left to go wrong when I go to use it.
One more thing for the safety police, in the pix, I have not reinstalled the PTO shields yet, as I just finished cutting down the old shaft and done the initial testing. Paint, shields, and final little tweaks come next.
