>People that accidentality cut their fingers in lawnmowers due to lack of safety features are allowed to sue the lawnmower company.

Anyone is allowed to sue the lawnmower company. Did they win?

The amount of "Do not put hands here" labels I've seen on lawnmowers would suggest that, yes, someone did sue and win (or at the least got a settlement) and thus the lawyers forced the companies to put disclaimers and warnings on the lawnmower, directly on the top of the deck in plain sight.
