Used to bump start the Ford 8N all the time.I used to notice kids or guys trying to push start manual trans cars and bikes and having a hard time. They were doing it wrong. You don't push start in first gear you push start in 3rd or top gear. First or second tries to spin the engine too fast ( 3.55:1 * 2.64:1 = 9.372)
So, on a wide ratio first gear T-10 with 3:55 rear gear, one rotation of the rear tire tries to spin the engine
almost 9-1/2 times! Put it in top gear that would reduce to 3-1/2 times - much easier to push or roll start.

We were on top of a long hill and rolling the tractor down the hill was much more effective than the 6v battery when it had sat for a while.
Warm, it would fire right up from the battery, but after a long sit, particularly in winter, bump start every time.
