Well.... i was just recently looking at different skidsteer attachments myself. My FIL as an older bobcat, and even though my tractor is small, i figured... anything the two of us could share, since his is a "standard" or "low flow", would be that much easier to justify. I'm just theorizing a breaker would pound the bejeezus out of your tractor (and your kidneys.... which are probably bad enough already! HAH!!). Just a thought, which you may have already tried, but you could call Bobcat of NH (Chichester? Or Northwood maybe?) and inquire with their parts guy. He is really good, and knows his stuff without having to look up everything in a manual. He was nice enough to spend a bunch of his time helping me find an odd hydraulic part, even though it had nothing to do with a Bobcat. FWIW, my FIL has said great things about him too, and he doesn't say good things about just anyone ! I don't recall his name, but i believe he is more or less their only parts guy. I would imagine he could tell you how many GPM and PSI you'd need to run that particular breaker. Good luck !
