Has anyone here ever used a MacKissic shredder PTO attachment on a Deere 140, 300, 316, or 318? How did it work? I have used a MacKissic stand alone shredder and didn't really like the way it aggressively grabbed stuff out of my hands. I'm guessing these were available through Deere back in the 70's and 80's. Lots of neat attachments available back then that are not available now. I am asking because I have a chance to buy one and would sure like to hear of anyone's experience before I part with the $$$.
