I own a 1954 Allis-Chalmers WD45. I mow my yard with it. I have all of my limbs and fingers. Grew up on a farm. Started driving tractors when I was 8. I know a lot of farmers who have never lost body parts.
Roll over protection? This article’s author is a snowflake.
Roll over protection is for people who do stupid things they should not have done and then protect the manufacturer from the inevitable lawsuit. IF you are using your loader it should have some type of counterweight in the back.
It is similar to the circuit that disengages my John Deere when you get off the seat or the PTO when you put it in reverse. Some dumb A$$ probably mowed over their kid and then filed a law suit against John Deere.
My oldest brother ran up to my dad while dad was cutting grass with the Cub Cadet lawn tractor in 1968. My 5 year old brother stuck his foot under the deck on the side where the discharge was. His foot was cut badly. Hospital, stiches, etc. Thankfully, no long term damage. Now all mower decks have a cover that protects against this.
Many machines have been modified over the years to protect us from doing stupid things. Everyone(including me) that has used machinery is guilty. Accidents happen.
