Broken Backhoe Subframe Advice?

[Roady]

Hello all,

I have a new TYM T273 with 54 hours on it. Tonite, the sub-frame on the backhoe snapped leaving it almost dragging on the ground behind me. I'll attach some pics here for you to see but I have a couple questions before I hit the dealer up about it as this is my first tractor.

1. I have left the backhoe attached since purchase. It provides good weight in the back, and I use it a lot. Is this ok? Should I be taking it on and off all the time? Is it too much stress on the sub-frame to have it on 24/7?

2. This is obviously covered under warranty (or at least it better be ). I can't see a weld where it broke, meaning I think the steel itself snapped. Should I demand a complete new backhoe or settle for a fix?

Thanks for any advice.

Roady,
The break should be covered under warranty. I'd get it fixed for sure.

I think it's a design flaw. My backhoe was attached with beams all the to the cab of the tractor. I can't believe they hve all that stess on such a small amount of mass.

From what I see in the pics it looks like they stack two pieces of tube steel on top of each other and weld them together. Looks like part of the weld brke which eventually lead to the tearing of the bottom tube. Not exactly the best way of putting it together.
I would ask that the whole subframe be replaced.

It is fine to leave the backhoe on all the time, using a decent subframe.
I do, and it is excellent ballast. This is the first I have heard of a
subframe breaking.

I would look at your pix, but us dialup folks need many minutes to
download such big JPG files. Please post smaller pix.

Where is your top link? I didn't see one in the picture but maybe I just missed it. The top link will prevent the bending load on the frame. That failure looks like a cantilever overload.

Shaley,

Do you mean the top link on my 3 point hitch? Looking at the manual, there are no connections from the BH to the 3 point.

 

[shaley]

The top link forms part of a "truss" type connection and will take more than half the stress away from the sub frame. I'd check for sure. Never seen a sub frame mount that didn't have some sort of "top link" connection to take the moment forces.

 

[Roady]

Steve, thanks a ton. I found some pics of another BH and sure enough there is a link there. The dealer never installed it. I feel alot better now. Again, thank you.

What Brand is a TYM? If it is a true subframe mount, you shouldn't need a Top Link.

I agree, my Kubota 4pt subframe mount doesn't have any kind of top link attachment and neither did a bradco subframe BH I previously had on different tractor.

 

[shaley]

Guys, Chill slightly, please. I chose those words carefully. Weather you use the real top link or a "top link" connection you still get the same structural element. A 4pt subframe is a truss and is still a top link type connection. Roady's pictures showed a purely cantelivered loading situation and that just isn't very strong.

If you look at THIS picture, the top link runs from the upper 3pt hitch link , under the backhoe seat and to a bracket on the backhoe. That is the part my dealer forgot to install.

I think I would take that up with the dealer. He needs to give you a new subframe and the toplink as well.

Absolutely. I went to the dealer today and will have a new sub-frame tomorrow. In all honesty, I'm happy that this was just dealer error. If it was a design flaw, I would have to constantly worry about it happening again. This tractor has amazing power and pound for pound, does more work than anything I've ever used. I'm really pleased with it so far.

For as much as I paid, they should have given me the whole ride!

Wow, sorry!

Is it a subframe or 3-pt mount?

Woods subframe for BH80X does not use any top connections.

If it is a 3-pt mount with no top link, I could easily see it breaking.

Good luck

pic#3 is a little blurry, but it looks like there is a rusty spot in one corner of the break. That would indicate its been cracked for a while. Glad to hear your dealer is getting it taken care of

That's the first thing I seen/saw ..... No Top Link ??
