At seven I use to drive a tractor with my cousin, we needed two of us as neither of us could reach the pedals, so we did a join effort.
we had to drive the tractors as that is where we were the most use, when baling,
I certainly drove a car at that age, around the farm, we had wooden blocks on the pedals, the car had no floor.
I drove dumper trucks, diggers, tenders boats from a really young age,
mine use power tools, as did I,
It is really important to learn respect for power tools and machinery, early in life.
Never had an accident, but then I had it drummed into me from the beginning how to use tools properly.
