Years ago there was a guy northwest of of me about 15 miles that ran all LP tractors except a 1468 IH with the V-8 diesel. and a "Big A terra-gator" with a old Ford gas engine. He had a helluva line of LP tractors in high horsepower (well for that day) The crown jewels were the (3) yes 3 Minneapolis -Moline A4T-1600 4 wheel drives on LP. I will never forget that auction as they sold his stuff. All the Minnie-Mo's sold between $5000-$5500. I do not remember how many big IH LP tractors he had but it was a bunch. As folks know engines burn a lot of gallons of LP. They guy had a 18,000 gallon tank. They sold it on the auction also.
