I acquired a b7100 tractor and bought a k600 backhoe. I know the b7100 takes a different model but I'm hoping to use the one I have due to hoq rare they aeem to be. I'm curious about the subframe, obviously they aren't a dime a dozen anymore and fabricating one is going to be my only option. Is there a manual someone could point me to to see what it looks like and where it bolts on the tractor?

Ther K600 is a bit large for the B7100.
Your going to have to make your own subframe, it needs to attach to the rear end and also to the bellhousing.
The subframe might be able to be made like the subframe for the 4520A
Go here: https://apps.kubotausa.com/illustrated-parts/
And search 4520A and look at the subframes.

Yeah I was afraid of it being too large for the machine, I do have another tractor that I could hook it if needed. Picked it up as a good deal, just trying to get it to work. Thanks for the info!
