BH77 backhoe attachment on B2910?

[GeoQ2]

I was wondering if I could get some clarity on what the correct backhoe attachment is for my B2910 Tractor and maybe the mounting kit info . There is a BH77 attachment for sale near me am I wonder if that will work? Any info would be greatly appreciated!

I don't see anything in the literature to make that work. It looks like the two options for a backhoe in your tractor model are the B4672A or BL4960B. Both of those back hoes are three point mounted.

You can find the parts list here:

I did not see any subframe mounts for your tractor that would indicate an alternative hoe.

@Henro had mentioned selling his 3pt back hoe for his 2910

Thank you for the information!
I have considered the 3 point route but I’m concerned about the B series structural strength .
Or am I overthinking it?

I don't have any experience with a 3pt mounted hoe as I've only had subframe mounted units. But, It would appear that your concern is warranted considering the way B series tractors are built in the rear end area. We've heard those horror stories.

I suppose it would depend on what your intended use for one is. They sure look like a PITA to mount/dismount if you have other 3pt mounted attachments that you use regularly.

Perhaps Woods makes a frame mounted unit for your tractor?

.
I know for a B2410 they made pieces that reinforced the rear of the tractor.
They bolted from the rear axel housing and went forward to the bell housing. It required a reinforced top link bracket also. Could be a B2910 had the same reinforcing pieces required to run the 3 point backhoe. This is what they look like for a B2410

Hard to say about overthink. I have been using my Bl4690A backhoe on my B2910 for 18 years, sometime a lot. For example, dug about 300 plus tons (Maybe 400, was a whole summer project on days when the ground was not too wet) of earth with it a couple years ago, to transport with my dump trailer for use around my pond and house. Dug many stumps out too, before I realized it is more efficient just to dig down a bit and cut them of below grade...

With the B2910 you certainly need the heavy duty top link piece. No question a sub frame backhoe is better and less risky. In my case, there have been no issues.
