What could do this to a 3720??

Made me sad to see such a nice machine destroyed like that. I can only wonder how the operator felt when it broke apart, if there was someone on it at the time....:laughing:

He might have been happy it wasn't him split in two. Just like I told my daughter earlier today. Things can be replaced. People cannot.

I can't believe they tried to pull it out with the tanker still attached.

The steering column and seat are damaged making me belive they came in contact with each other, and maybe with an operator sandwiched in the middle. This would lead me to believe it was not pulled apart but more likely dropped or struck from the front. Struck from the front doesn't seem likely since I don't see any damage to the loader.

Snapped in half from a combination of a poorly designed BH sub-frame setup and operator abuse with the hoe. These Deere's don't/didn't use a sub-frame for the hoe that ties all the way into the front of the tractor or loader frame. It just uses the rear axle housing area for support, leaving the bell housing area unsupported. We used to have a 4400 (which is structurally nearly identical) and I can see how this could happen. I'm really kind of surprised Deere hasn't gone with the full length sub-frame on these.

Although I agree a subframe to the front of the tractor would make sense, you don't know how this happened but only speculate while acting as if you were there. If Deere wanted they could make these tractors much more rigid, but would you pay what it would cost? These tractors are not dedicated backhoes with the intent to do work typical for the machine and horsepower. Adding all the extra iron may prove to make it too heavy and things like using a belly mower a pita.

Let me start by saying, I'm am not intending these comments to start a brand war.

All Kubotas from 23 to 51hp use a full length sub-frame that tie the loader and backhoe together. It is fundamentally the same design that they use on their industrial TLBs, except on the standard tractors the two sub-frame halves are bolted together, not welded (for easy of installation, cost). Also works with a mid-mount mower. With that said, Kubota didn't always have it right. For years they used 3pt hitch backhoes and had similar problems to what this thread is about.

Again, I'm not trying to start a brand war, only using Kubota as an example because that is what I know. I'm sure other makes of compacts use a full length BH sub-frame, not sure why Deere doesn't think it is important also.

You are not starting a brand war as none of us really know what happened to the Deere being discussed in the pictures. Any brand of tractor could sustain the same damage in any number of situations and it's too bad we don't know the exact cause of the damage.

Very well said, there is alot of scenarios.
