The one posted is pretty neat (tri flathead really
), any history? Was it a restored vehicle, or a new creation? Looks like something new? At that time, farm implement would be up to par to the v8. But you never know! Pair of 37 motors to run the belt.
Back in the day, engine services for farmers was actual. Drive your hit/miss or belt driven machine to the farm. Run the thresher then go home. Or a farmer could put a model T/A on blocks in the rear and bolt on a belt wheel to the rear. Good thing they had a throttle rod so you could set throttle and didn't have to sit in the cab and run the throttle.
