Help with used BH90 subframe? (on L3240)

[mainenate]

I'm looking at a used BH90 Kubota backhoe, for my L3240, and I'm trying to figure out if this subframe can be made to work on my tractor. They say it "fit's L30 series tractors", but the sellers just got the hoe with the farm they bought, so they don't know much about what tractor it came from, or really much about the hoe at all.

It doesn't look quite like the factory frames I've seen - maybe it's a home-built subframe? What dimensions should I be looking at on the frame and on my tractor to figure out if this works? Where does the subframe normally attach to the tractor?

Any help is very much appreciated! I don't have experience with Backhoes so I could really use some more experienced eyes on this.

Thanks, Nate

Doubtful it's factory Kubota. Do not use it's much too light weight for a BH90. On my BH90 and Kubota L4330 tractor the main side brackets for the loader were removed and longer and heavier backhoe brackets installed. The longer brackets have hooks on the rear for the bottom backhoe pins. There are also other brackets needed. I'll take photos tomorrow if you want.

With the factory backhoe subframe extending a long length under the tractor it protects the mid section from the pressures of digging. I've seen older tractors broke in half from backhoes.

That is not the factory sub frame for the BH90.

Thanks folks. That's what I suspected, and I appreciate the confirmation.

I'd really appreciate that!

Is there a way to look up the part numbers that I'd need for a BH90 on the L3240? I'm not having much luck searching the internet. Maybe it's in the manual for the BH90?

You potentially appear to have parts from multiple equipment mixed in. I do see some of the proper BH90 subframe in the photos. Here is what your looking for as a BH90 subframe for your tractor.

Go to one of the Kubota parts lookup sites such as Messick's. Looks like a couple variants used so be careful. Here's a diagram showing general idea of subframe and yours might be slightly different. The main side brackets replace your loaders subframe.
