THE LARGEST PLOUGH?
What is claimed to be the world’s largest plough is being used in the United States to bring to the surface the fertile peat soil buried under several feet of silt and sand by floods that occurred some years ago near Santana, California. The size of the rplough can be gauged from the fact that it works to a depth of six feet, constantly turning and lifting five yards of soil as it moves through a field. The hydraulic lift used to raise it out of work has a pressure of 7501 b per square inch, and is operated by one of the three crawler-type tractors which are used for pulling it, and which provide no loss than 150 draw-bar horse-power required when tough, dry soil is being worked. The outfit ploughs half an acre an hour, and it is said that often the increased yields obtained from land so treated will pay in a single season for the ccst of this aptly styled “super ploughing job.”
