On the cutting action of wheel cutter

Abstract

The author had the several cutting tests on a small type silage cutter, which revealed the following facts remarkably to reduce the required power.
1. As for the cutting mechanism, it is better to cut from the inner side of the shear plate to the outer side.
2. By increasing the affixed angle of the cutting knives, feed material can be free from being pushed towards the back of the knives or the wheel arms, consequently the required power is greatly reduced.
3. Difference of the flywheel rim weight is so little concerned in the required power at the constant load. It is necessary to be driven with the constant number of revolutions by keeping the belt from slip.
4. Difference of the blade angle only little influences the cutting resistance. Sharpen, therefore, the knife edge, even if the blade angle be larger, and it will show the better result than in the case of a dull blade with a smaller angle.
