A friend and me used old john deere tractors to
work his hay after he moved full time to his place.
He had several A's and a G that was a coal oil
tractor. Back then, I'm guessing an electric starter
was an option. The G had a big petcock on each
side for each cylinder, and you opened those and
you'd get the big flywheel on the side spinning
by hand with the gasoline on, and it would catch
and you'd hurry up and shut the petcocks and it
would get warmed and POP-POP-POP-POP-POP
and when it got hot you turned off the gasoline
petcock and opened up the foofoo.
Whatever you do, just don't forget to turn off the
foofoo and turn the gasoline back on before you
shut it down
My last using relic tractor was a M ( or MT- I forgot)
