In Victoria Australia I met a couple, Leslie and Bob, 80 and 90 years old, who shared a single car. Their parents had bought a 1929 Model A brand new for their honemoon, and Leslie and Bob still drove it.
Well, round about 1949 they decided they needed a tractor. They got ahold of another Model A and the rear differential of some sort of Ford tracked gun tractor and slapped them together. The engine was the original 4-cylinder (Leslie says it puts out 24 hp) so how to get tractor torque out of it? Why, just link two gearboxes together! They put tractor tires on the rear and added a crane boom and the result is some sort of Mad-max ute, fast enough to go to town on but able to do all the work around the farm. They’ve never needed a tractor since.
It had a huge alternator on it to generate power. Leslie had all sorts of tales of speeding around country roads, Bob slamming the secondary transmission from low to high (no clutch, just timing) and Leslie holding tight to the PTO that constituted the passenger seat.
