Backhoe backhoes

[3RRL]

I've got a 3pt mount backhoe that's dug quite a lot for me without a subframe on my 55hp Kama. Some of the stress is placed onto the hydraulic box where the top link is attached, so I thought it better to make a subframe for it, just in case. It takes a little reverse engineering, but it can be done, and the result is a much better attachment to the tractor dispersing some of the stress to the frame etc.
Here's a thread where I built my subframe. acouple years ago.

Seven Point Backhoe Mount

Another guy here with a 3pt, a 4672 on a KubotaB7800. ZERO problems. Not to say I wouldn't mind a subframe but then I could not attach a MMM. Kubota warranty does cover any damage when using a 3pt (must be a Kubota BH though) and the mounts for the 3pt are wicked mean looking.

I have a subframe and MMM on a b3030 - I'd have thought the b7800 would be the same

Hmmmm was told it couldn't be done on mine, all your attachments are from Kubota?

....I would be interested in hearing how some of you have made subframes for small backhoes. Like where does one attach the subframe? I would be interested in making my own subframe.

I encourage anyone with the interest to make their own subframe. If you
do a search, you can find many posts on custom subframes. I believe I have
posted pix of 3 of the 4 full custom subframes I have built. Different tractors
offer different challenges, in terms of clearance, available bolt holes, height
of the rear axle casting, etc. I have helped a few owners with long distance
guidance, starting with some strategies (see text file). You have choices
to make on how stiff and solid you want it to be, if you want to use the
toplink casting on the tractor, how close to the rear you want it mounted,
your seat strategy, etc.

If you do decide to go ahead with it, others on TBN would like to see pix.
