Wonderful New Agricultural "Juggernaut" - The Gyrotiller at work. The two tanks in front are formed-by a radiator and a huge thermos tank. By a pump attachment, the hot water is transferred - at the end of a day's work - from the radiator to the Thermos which keeps the water ***** and ready for re-transferrence when work is resumed.
