Diesel efficiency and Aircraft Engines in WWII
There is no question that a gasoline engine could and has been a significant contributor to the american and for that matter the world agricultural community. However, both engine as we are all aware operated totally on different priciples.
The advantage of the diesel is the low flashpoint for safety the low rpm/torque characteristics and the fact that they thrive on heat.....running hours on end at very low speeds as we all know generates tremendous heat through the whole machine....heat bring us friction and wear...hence the gasoline engine is not efficient with today demands on farm equipt.
At todays costs the gasoline vs. diesel per gallon cost is no longer a bargain but longevity is the trade off.

Diesel efficiency and Aircraft Engines in WWII
Man we have really got one going here now...I think we are all on the same page but the question in TOURQUE....if you examine the hp/torque ban on deisel engine ant a given HP vs. gasoline you will answer the farm tractor question. In gasoline engines as our hot rod days it was torque that we where able to apply to the concrete that made us the fastest but we needed high HP to acheive that mission of course the high HP then gave us the top end to win overall.
Farm equipt. Tractor trailers pull a lot of weight and to move the weight they need a lot of torque but the engines must met thst power ban at a low HP...ie. Cummins 6cyl diesel 245hp@320 lbs.torque...etc.
Gasoline farm tractors used Bull Gear systems in the final drives at the wheels to generate additional torque to move the loads these bull gears where another source of breakage and maintaince. Again deisel has a low flashpoint you know kerosen and is safer in day to day operations...have you seen a gasoline JET???

This is really getting exciting now....you know I have forgotten totally what the orginal mission was...but I enjoy the discussion
