Probably one of the coolest attachments for the 1963-1967 John Deere 110 and 112 Round Fender Lawn and Garden tractors is the Model 20 Compressor. I have been fortunate enough to own a couple of these attachments over the years. The first I purchased at an auction in late 2013. Often times when you find these air compressors condensation has rusted out the bottom of the tank. I still have my first air compressor that I replaced the tank on. Here are a few videos on their operation and use.
