Going back 60 years or more when I was 10 years old.
Our neighbors, father and son, had a new two stroke rotary mower, one of the first rotary push mowers for home owners. It smoked so bad no mosquitoes would come around.
The father and son would start the mower and then, with each holding two wheels above their shoulders, trim their hedge. No safety eye protection. Each had to absolutely trust nothing would make the other let go of the wheels and the mower then swing down towards the other.
The FEL method seems so much safer and easier.
