That is fine Caruso.
If every one was as careful & considerate and in such good health as you the world would be a wonderful safe place to live in.
However in any particular years I would get at least 3 mowers with electrical flex wrapped around the blade spindles cause the idiot owners was draining the swimming pool or charging a flat battery or some other perfectly normal thing to do , but they forgot about the power wire and ran over it.
YOu could add at least a dozen garden hoses to that but they are nowhere near as potentially fatal .
Had only one customer ever who had a heart attack while mowing the grassy verge.
He fell off about 10 houses down the street and the mower continued another 300 yards or so side swiping parked cars till it went across a T intersection and came to a dead stop into a brick fence.
When he came home he had a second heart attack when presented with the damages bill that his household insurance company refused to pay.
So while admittedly quite rare these thing do happen.
I mow a very steep verge with a compound slope and regularly have to step off to prevent a rollover so again without a functioning seat switch that mower would have shot off causing a horrible accident , And yes I should be using a walk behind but it is 2 acres of very steep hill .
Seat switches can be modified, I do it all the time by simply popping a self tapper into the plunger so it does not shut off the engine when you go over a bump or shift your weight to look behind or get better traction .
SO there is really no excuse for dissabling them
I never bragged about how 'safe' I, also, made no comment about how 'healthy' I am. I do regularly visit my cardiologist, and, via tests, have been given a clean bill of health regarding my heart and surrounding arteries, so, while not unimaginable, the likelihood of my being rendered unconscious while mowing is very unlikely. My lawn includes no slopes that require me to routinely exit my mower to avoid being trapped/injured in a rollover. Additionally, mowing my lawn does not require me to venture out onto the street where, in the unlikely event of a heart attack, my machine would run on without me to inflict damage to numerous other vehicles.
I explain that I disabled these "safety provisions" because they infringe on my convenience in using my unit to cut my lawn, and many on this cite invent all sorts of very unlikely scenarios that could justify a rebuttal of my position. That's ok. Continue your cutting in forward only if it suites you. I don't care that much about what you choose to do. I am 70 years old, have been using mowers, push/walk behind/riders, since I was 9 years old. Pay attention to basic safety and you will survive use of the fine machines that we have today, no need for these restrictive safety devices.
Happy mowing,
Caruso
