My guess would be that it’s too big for your tractor, based on the fact that the image you showed says a 36 inch buckets available for that backhoe
In addition, I believe the backhoe available for theB7510 is what was mentioned above as the B4672. This is a three-point hitch back hoe. With a three-point hitch back hoe you need to add a reinforced top link bracket minimum, and maybe some other supports to the frame of the tractor. I’m not sure.
Don’t expect that you can just hang a three-point hitch backhoe off the back of your B-7510. If you do that without the heavy duty top link bracket, you can end up pulling the back off the transmission case.
Just something to keep in mind. I have a BL4690 for the back of my B2910. I was always happy with it, but once I got a small mini ex with about the same capabilities… but that’s another story. The mini ex sure is better!
I think the backhoe designations start with the letters BL but I’m taking that from memory so I could be wrong there.
Just checked. B4672A and BL4690A where are the two backhoes available for the B 7510 through B 2910 series.
