Someone could really cash in on this deal....a compressor attachment for the lawn tractor. I liked the John Deere compressor and tank setup...but would beef it up some, larger air tank (20 gallons minimum) and larger compressor.
I frequently have a problem where this equipment could be of great assistance. Only last weekend, I wanted to pump up a tire on the combine which had gone flat over the winter. It only needs about 25 pounds of air, but it is a huge tire and with a small, single cylinder compressor, it takes a long time. I have a larger twin cylinder compressor but the machine shed where I keep this equipment doesn't have adequate electric capacity to run it. I have a 5000 watt generator, but again, it will not start my larger compressor. The attachment on either the JD or a PTO driven unit would be used frequently for this type of situation and would also allow the use of spray paint equipment, air tools etc. far away from where electricity is available. Another good thing about it...it doesn't require another gas engine to maintain. I have about enough gas power equipment to keep running and don't need another one. On the JD compressor...a quick detach system could be used here with a good handle, so you could simply lift the entire attachment up and off the front of the tractor, making it easier to return to mowing.
So guys...opportunity knocks. The whole thing could be built with off the shelf products. Just build the proper attachment frame and bolt the pieces together. Product liabilty issues may be the only stumbling block.
I can already visualize a front mounted compressor and tank on my CC 3100...running off the front PTO drive...so...shaft drive to a small drive pulley, then up to the main compressor sheave. It would take up more room in the garage, but if it were a quick detach, it would not be left on the tractor anyway.
