how to build your own custom backhoe subframe

   / how to build your own custom backhoe subframe #241  
Thx, JAXS.

What model Kubota, and how did the loader subframe fail? I have had or worked on a few regular Bs, and owned 2 of the industrial Bs (B20 and B21). The regular Bs are not very stout, and need a lot of help if sporting any backhoe, and the hoe should be no bigger than 6.5' IMO.
B1750hst. Subframe only extends 8" passed bellhousing connection resulting in cracked & warped coupling plate, busted out bellhousing holes,shattered clutch/pressure plate and damaged propeller shaft. If I succeed in repairing damage I will use info from this thread to fab brace extending to rear axle. A L2350 nearby suffered same fate 10 years ago and for lack of parts sat in barn since.

I agree dfkrug, thanks for replying. So the weight of the hoe will be on the lower 3 pt arm(s) axel/rod, right next to the steel frame that also holds the ROPs as this is where the subframe in designed to mount. See picture below

Sorry for the long delay. I finished the backhoe subframe. It's a woods bh650 to B2400. I ended up using part of a woods subframe for a b7800 I think and then extended it to my existing FEL as it has some brackets already welded on that worked great (see pic). I used 3x1.5 channel in 1/4 for the extension and 3x.25 plating as reinforcements. Rear height is 9 inches to the bottom of the subframe.

This design uses the existing 3pt rod in the rear and hangs on it. The 3pt arms have to be removed to install. I painted it kubota bright II orange and then cut some labels to match (and yes I kept the OEM stickers on the base as well as cutting a new Woods for it too :) . But I liked the Kubota on the boom so that I left.

As a side note it works fantastic for cutting firewood out of heavy logs. I chained a logging grapple to the bucket and am able to pull around and lift 12-24 inch diameter logs in considerable lengths. I then just buck them when in the air. I used a boom pole for this last year but the hoe is much faster as it can maneuver itself as the boom pole required the tractor to be moved around instead.

Paid $1500 for the hoe, $200 in metal... and $60 in paint.

Oh, and yes the ROPS gets in the way if you use the chair. Next up is extending the OEM ROPS up 12 inches and putting a folding plate system in as well at the 2 ft mark on the existing ROPs.

...and the experience, priceless. Looks good!

There are lots of good deals out there for orphaned backhoe attachments. Prices are way lower than they were 20y ago, prob due to the explosion of cheap Chinese excavators. There are things my backhoe can do that my mini-X can not (dig harder/deeper, and move faster).
