Thank you Jnschnit you see I purchased a Kubota BH70 from an electrical contractor and I sent a friend to pick it up. Now I have the attachment yet not the subframe and the guy I bought it from will not take the frame off his Kubota. I have installed the BH 70 on my old Ferguson yet would like the option to but it on my 2620. Heck I'm not even sure of the model I have yet will afirm that when I get back to ColoradoJust to level set, are you talking about the Kubota BH70 or the Woods BH70?
The Kubota BH70 is for the B2601 Tractor. The B2620 uses the Kubota BH65. In either case they are mounted via frame mount. Check Youtube for a video of a dealer installing the frame on a B2601.
