I have a John Deere 911 Extender Hoe attachment (model BH11) on my Case 1845C skid steer (yeah... it's tippy all right!). I need a thinner 3-tooth bucket (8 or 9") to bust through some of my rocky soil. Anybody know where I can find one? I'd also appreciate any advice on whatever Specs I should use when searching for one. Keywords I've used on Google like "JD 911 hoe bucket" or "John Deere BH11 bucket" don't produce any sellers. Thanks.
