The spring-tooth harrow, with flat spring teeth bent almost to a complete circle, is a tool that is not in general use in America, but implements of a similar character are used to a large extent in Europe. It should be classed as a cultivator rather than a harrow. It is adapted to hard, compact soils which require a tool of good penetration. The teeth have such long blades with so much spring that the machine is not damaged in passing over stones or low stumps. The draft of a spring-tooth harrow will depend upon the adjustment given to the teeth, but under average condi- tions it greatly exceeds that of a smoothing harrow. The Harrow Cart. Probably there is not another imple- ment attachment that can be bought for the same money that will dispense with so much hard labor as the harrow cart. To be a satisfactory device it must be rigidly built with angle or U-bar arms extending to the harrow evener, with provision for the cart wheels to castor in turning. The wheels should be high, 32 inches being a good height, and provided with tires about three inches wide. They should also have dust- proof removable boxes with easy means of lubrication. Lastly, it should not be overlooked that the cart should be provided with a comfortable seat and springs to support it. Utility of the Disk Harrow. The disk harrow is an implement well adapted to deep surface cultivation. For this reason it is used for a variety of purposes. To prepare plowing for seed in the spring or stubble for plowing in the fall, it is equally useful. For covering broadcasted seed in.
