Physically, fuelling an engine with water is impossible! And while it is theoretically possible to dissociate water (separate it into gaseous H2 and O2) then use resulting H2 for motor fuel, the problems of handling and burning hydrogen today are immense. To the typical farmer back in the 30's they would have been insurmountable. Further, dissociating water requires a LOT of energy (electricity). It's unlikely any tractors ever ran on hydrogen fuel.

I suspect rather you refer to early tractors which ran on kerosene or distillate. These fuels tend to cause destructive engine knocking under load. One way around this is to add water to the fuel/air mixture at the carburetor - the added water reduces engine knock. Thus these tractors had a separate water tank next to the fuel tank. So a casual observer it might look like the tractor “ran on water”.

Perhaps this is what you heard about??
