I learned how to drive on one of these:
A close look will show two pedals for the left foot, a clutch (inboard) and left brake (outboard) about 2' down from the seat. I was 6 years old when I first learned how to work the tractor and I had to get off the seat and stand on the clutch with most of my weight to move it. Fortunately, the throttle was a small lever up under the steering wheel which you set and it stayed. Life got easier when I was seven and weighed more.
I went for my DMV driving test with a 3-on-the-tree Dodge Dart. After it was over and the DMV guy gave me my license paperwork, he said: "I bet you grew up on a farm."
When I asked how he knew he said "You can always tell a farm kid. They drive like they've been doing it for ten years."
Boy, was he right.
