The development of pulling and U.S. Military (and perhaps European vets also) July 08, 2024 05:18AM
Random thought- the U.S. military had an indirect role in the development of pulling.

Consider- in the very late '60s and 1970s, there were numerous vets of WW 2 and Korea, plus other former soldiers who do not serve in one of those wars. I believe without all those people's experience with aircraft and tank engines, the mod class may have developed very differently.

Without people with a working knowledge of allisons, tank engines, etc, the heavy mod classes especially would have looked much differently. I wonder if there would even have been enough tractors for the 9 and 12 mod classes to have developed. I can't speak for how military people may have contributed to the growth of pulling in Europe, but there were also lots of aircraft engines as the European mod classes developed.

Your thoughts?

A tank or aircraft engine is not really different from other automotive engines. If you have the manual and a well trained engine mechanic (one who actually learnt how to rebuilt engines, not a high school trained "car mechanic") you can handle them.

What probably would have helped in the development of e.g. the Allison engine in Tractor Pulling: If the "goals" they were trying to reach with those engines and why they did what, would have been better known.
Like: What were certain "limits" on the engine that were accepted due to being lighter, having a smaller surface area or didn't matter to them for various other reasons. Once you realise they were made to do only one small rpm range, in thin air you kinda get the idea though.

What would still help, if some of the knowledge in manufacturing certain parts would not have been "lost" and now has to be rediscovered with trial and error - or dug out from 80 year old folders in company's archives.

Totally independent of the army people which directly had contact to the big engine stuff (tanks/airplanes), there had been thousand of tons of machinery around close after ww2, to build and maintain this nice stuff. High accurate lathes and mills for e.g. aircraft parts were really cheap at that time. Many interviews with people alike Gary Densham, Carl Olson, Bob Muravez coming up with evidence that some of the greatest TF car/component builder in the 50s-70s have taken this opportunity to get hand on plenty of this equipment.
