We have sold dozens of these backhoes and we do see this occasionally. In fact years ago we were complaining to Jeremy at KMW about the bolt issue when he politely and only with a hint of sarcasm asked if we read the manual. 
It was then we noticed the 50 hour bolt change recommendation. The problem is that the bolt will brake, but part of it stays in the hole and the chain is then just grabbing part of the weldment, which tears the weldment.
The good news is that a little care makes this problem go away. Keep the chain lubed and adjusted, and that is easy. Change the bolts occasionally before they break.
The only other issue on the earlier 3710's was a plastic connection in the control valve. They will break if you are a bit heavy handed. We see customers with hundreds of hours with the plastic pieces in good shape, then we get the guy that breaks them every 50 hours...repeatedly. Before anyone takes offense, I'll admit they should not be fragile. All the newer backhoes in the last few years have a different valve setup without the plastic parts.
I think the plastic pieces are about $20-$25 each, something like that, so not real bad. Not a bad idea to have one in your toolbox just in case. They only break on long weekends when your dealer is closed, and if you are in the middle of a critical project right before a rainstorm, that seems to make them break as well. Not saying you will ever need one, but if you do it is an easy fix and not real expensive by tractor standards.
We have sold a couple hundred of the Mahindra/KMW backhoes over the years and they are good solid machines.
