I mowed our lawn with a riding lawn mower when I was six.
I had to practically stand on the clutch to change gears.
Our son was doing it when he was 4. No gears but just stood up the whole time. Next was learning to ride the custom bicycle his dad built. He learned to rise it before he learned to stop it so he just ran into bushes. Scratches all over.
Ha ha! Thank you for bringing back a great memory. We had an Oliver Super 55 that I had to stand up off the seat to engage the clutch. Was not the safest act. I didn't have enough weight to use the brake pedals on the other side at the same time without the clutch pedal lifting me. So much fun to remember.
