backhoe subframe for a B-7510 bota

[Dongerosa]

Here are some pictures of a kubota subframe on my b2710 that I took awhile ago. If you want I can take some better ones of how its bolted to the tractor

Looks as if the Bota mount connects to the axle and the rear of the differential housing? is this correct? I drove past the local Bota dealer but no hoe's on a B series...just tracked diggers.

Did some machining of axle plates, welded them up and mounted them. I think it's going to work! it's got too. lol

next steps... locate the 1 inch hole for the pin in the subframe 2x5 tube to pick up the axle bracket, drill, install pin, test fit...then weld the pin in. Then start on the loader attachment point brackets.

I took some more pictures, it was hard to get a good view with the tire in the way. Kubota went to a lot of trouble to brace the subframe to the upper transaxle. My guess is this is for side to side or twisting load that you get when setting the stabilizers and digging.

Kuboter...thanks for the pics' So they are using the axle flange, ROP's and the loader as the pick-up points! It looks like 1/2 plate running forward to the loader mount? my design for the sub frame will be two 2 x 5 rectangular .125 wall tubing on each side of the axle. picking up the loader forward and the axle flange at the rear. These two side tubes will be tied together with the same size tubes in just behind the axle, and then about midway between the front and rear axle. This structure should be really stout, or robust. So, I'm hoping that all the loads from the hoe will be transfered thru the subframe to the loader mount. the rear axle mounts will only be supporting the tractors weight? I guess I could look at what it would take to pick-up a ROPs mount. Not sure if it's nessecary?

It's bolted just below the ROPS to the upper Transaxle. I have no doubt that your mount will carry the weight. I'm just thinking about the side load. It might not be nessary but if you look at the complicated bracket that Kubota made they didn't do it for no reason. I just keep picturing the twisting load that you would get if you put just one stabilizer down all the way and how those upper mounts would carry that load nicely. I do over think / build things so...
