Find someone willing to learn and keep it.

The torque required to turn over a (assuming) diesel tractor engine would probably be enormous. Old cars had a 5:1 compression ratio back then compared to 12:1 today, so to hand cranking was possible. I don't know what the comp ratio was back then for a diesel engine, but modern diesels are @18:1, thus very difficult to turn over.

If you see an old aircraft/tank engines, from the 30 or 40's you might see this. More reliable than an electric starter and battery back then.

Yep. Coffman starters play an important role in the original Flight of the Phoenix.

I understand that part... but i still dont get how a shotgun shell turns over an engine... diesel or not

If you read the wiki article. What happens is that when the shell goes off, the expansion of the gas, is used to turn the engine over. In some forms the expansion of gases may go directly into a cylinder replicating the explosion of fuel or will engage a separate starter piston that will turn it over.
