I found this one locally. It's a LT-112 for Bobcat MT-55 or 52. I have a 55. The Bobcat website says LT112 has a maximum digging depth of 2 feet. However, the seller claims it digs 3 feet. It has to be 3 feet for me to make it work because of the code requirment here. Anyone has any experiences and knowlege about it? I can not easily go there and test it out. Thx for any inputs. Erwin
