File:TractorPoweringWaterpump.jpg

Description
English: A picture of a Fiat tractor powering a waterpump, which is used to pressurize water and send it to a automated sprinkler/self-unrolling irrigation reel system (not shown). Note that the reel (not shown) automatically reels in the waterhose on which the sprinkler is mounted. The sprinkler is also automated to move its waterbeam left to right (by pivoting), and the whole system is thus capable of irrigating a plot of land. See the AutomaticallyOperatingReel-image to see the reel with sprinkler. Note that the tractor shown still uses a polluting engine running on fossil fuels, yet were the tractor to be outfitted with a compressed air engine, the tractor/water pumping would be very environmentally friendly aswell (besides being easily movable).
