I was looking on the kubota website and it has the M4011 backhoe listed for the 6040 tractors. My question is why isn't there anything on here about that backhoe? I did a search and nothing came up. That is hard to believe because looking at the numbers on the website it looks like one hoss of a hoe. Does anyone have any more info on these and what one of these would cost, subframe mount I guess, and it also says there is a mechanical thumb or hyd. thumb option. Thanks for the help. Nate
