Agricultural engineering. 2?4 AGRICULTURAL ENGINEERING fodder is fed directly into the cylinder. The third type of machine has a large number of narrow, hook-shaped knives arranged spirally around the main shaft, and may be desig- nated as the spiral knife machine. These cut as well as split the fodder as it is fed directly into the cylinder. Considering the relative merits of these various types of machines, the radial knife certainly has the advantage in simplicity. The fan blades are attached directly to the main cutting wheel, and this single rotating part forms the principal portion of the machine. All that is required in ad- dition is the feeding mechanism. The knives of this machine are more easily sharpened, as they are at least straight on the flat side. As the knives are often supported their entire length, they may be thinner, requiring less grinding in ITig. 175. Cutting heads of three types of ensilage cutters; 1 is the radial knife, 2 the twisted knife, and 3 is the spiral knife. The twisted knife machine is capable of very rigid con- struction and is safe against an explosion from overspeed. The spiral knives may be sharpened by filing without being removed from the machine. Most machines can be.
