Learned the hard way what happens when you go too fast on a lawnmower

Litterally simply constructed this quick mower and crashed it the day after it was “finished”. Happening hill on gravel with a pointy left flip on the backside at 35mph, rolled it, flew off of it, it landed on high of me and drove over my head, arm, chest and leg, it stored going and flipped finish over finish which broke the entrance spindles and broke a wheel off and barely broke the sprint, I loaded it up and stuck it sufficient to drive it to park it. Lengthy story quick, please put on helmets guys, I wouldn’t be typing this proper now if I hadn’t. I used to be extraordinarily fortunate and walked it off with a number of scrapes and bruises, nothing severe, ol mower is getting some modifications to make it safer
