Product liability for industrial and agricultural equipment gets interesting.

You can modify a household lawn mower and if you get maimed by it by those modifications, you're at fault.

However, for industrial equipment if you can modify it - the manufacturer is likely liable. Consider how often you hear about deaths due to manufacturing defects (the stats for deaths for framers is 60 - 70 per year per 100,000 in the US).

That’s interesting if true, but do you have a better source (ideally, a court case)? I don’t see that theory of liability discussed anywhere on the page you linked.

It also has two case studies in it.
