An idea if anyone wants to try for shredding, mulching :
Two older modified 21 inch Snapper mow decks from the 80's, commercial type with the flare to the inside bolted together mounted to a stand upright. The decks are Hi-Vac snail shell design which would lend itself well to this and of 12 gauge high quality steel, way better then the garbage on the market now. Most older horizontal Briggs or Tech engines have the pto end mounting holes so it can be mounted to the deck. Use the Snapper blade holder and key on the Snapper Hi-Vac blade with mulcher wings or the ninja blades, heck !, custom shredder blades can be made up with this.
One end of the deck will be the intake pointed up, the other end will be outlet pointed to the side.
Disclaimer : If you improperly build and use this and end up injured or damaging the machine, the fault is no one but your own.
