I was hauling creek gravel up a steep hill in ours one day, and that motor twisted a rear axle in half (Dayton 2-speed rear end, 1-5/16 axles, IIRC). Unfortunately that rendered the emergency brake useless (band brake on the driveshaft). I was too heavy to dare trying to back down the hill. All I could do was sit there and stand on the brakes until the loader operator noticed I hadn’t come back and came looking for me.
I learned how to drive on tractors and dump trucks long before I was ever allowed to drive a pickup or car. My dad had a 57 Ford gravel truck w/292. First time out I could not get the tail gate to trip, I was pulling on the rope and the lever just would not come down, meanwhile the box was going into the air. When I looked forward all I could see was air! The front was off the ground by about 4 feet, my dad was along side laughing is rear end off. Gravel was spilling over the top of the gate and it slowly went back on all fours.
I hired on as a custom combine truck driver at 16 years old, went south with them. I had no drivers license. Drove a 2 ton 1966 Chevy with the 292 six in it. Never got caught as no one cared back then if anyone had a drivers license or not.
How I miss those days of simplicity and freedom!
