Wow that was an era when “safety equipment” was a misnomer.
Safety equipment is for wusses.
I took almost that many chances on a Ford 8N farm tractor when I was twelve years old. And they could achieve a top speed of about 25 mph (with the Sherman Step-Up transmission).
Nothing like a load of hay bales pushing you downhill on a road covered with loose gravel. Just steer through....
Eventually they had “razorback” ridges that came up to head level as roll protection. Other than that, it was helmets and safety harnesses.
Safety equipment was the guy with the fire extinguisher in the infield.
Besides, he's got his goggles and helmet, and at least two of his tires appear to be in working order. ;-)
