Schramm tractor

For those that don't know the Schramm had a straight six cylinder engine the forward three cylinders powerer the engine, the aft three compressed air into a huge accumulator tank. That tractor usually spent abuot 14 hours a day running as a compressor and another 2 dragging gear around the flightline (or doing wheelees)lol!

They used a standard IHC truck engine modified to run on the front 3 cylinders with back 3 cylinders compressing air. As a tractor they were kinda underpowered and clumsy. And they did not have the air capacity of a dedicated compressor unit of similar cost. However the Pneumatractor’s ability to move itself around, to pull other equipment and to perform light blade work made it a very handy for highway departments, railroads, on construction sites, etc.

I submit a Pneumatractor would be very collectable. I recall only seeing 1 or 2 in my 15 years of visiting old iron shows. Certainly more unique and interesting than yet another styled A or Farmall H! And it’s being an “assembled” machine - assembled from other manufacturer’s standard products – most repair parts should still be available.

I say go for it!
