Was recently talking to a guy about a BL 4690 Kubota backhoe for my B7800. Don't know much about this model. What year range were they made in? This guy thought it was like a 2000 model. I have seen that it has a 7.5 foot digging depth. Was wondering how much it might weigh? and if it would be a good match for my tractor? Any info would help, thanks.
