Pretty amazing that it broke. Were you putting any unusual force on it when it broke? Is the backhoe and frame the correct match for the tractor? Tractor hydraulics are all at factory specifications? Was it the weld that broke? ....

Thank you for asking, No, I was on my way in from the woods with a loader bucket full of pine wood when the backhow dropped down . The frame broke (rectangular) broke on top and down each side the bottom just bent. The tracdtor was bought new with backhow and loader bucket in 2009(date on picture is not correct) There is a weld on the top where the frame is doubled from there back. The tractor is used mostly to bring in firewood. I did some backhoe work for township,dug grave,and swimming pool.One problem with the backhoe is the outriggers don't stay tight about 5 minutes work and I have to tighten them.When taken in for the warranty inspection this problem was mentioned to them they stated nothing was wrong with it. This problem causes the tractor to move. Do you feel this could be part of the problem. Thank you ....

I'm sure the outriggers not staying tight would add to the problem. However, I can't think of any good reason why the backhoe frame should fail under normal operating conditions. To me it sounds like poor design or a manufacturing failure. Sorry to hear about this. I would bring this to the dealer's attention. ....

It has been years since I worked with welding inspection so may be off here, but it looks like right at a weld. If it is look for damage to the metal itself such as base metal being cut out with the welding itself and thus weakening it. Think it is called undercut and should be easy to see with paint off of it. At same time the metal may had a weak area there and it just took time for it to flex enough to break.
I suspect the shock loads that frame gets is more from driving over rough road then digging would be. ....
