Studies on the Optical Profilograph (II)

Measurement of the Effect of the Slight Revolution of Plow Bottom on its Shape

Abstract

Using the Optical Profilograph, the author measured the effect of the slight revolution of the plow bottom upon its shape, comparing Japanese plows with Western plows, and obtained following results; 1) The Japanese plow is more stable in its shape than the Western plow. 2) With regard to the stability, the share of the Japanese plow has approximately the same tendency as its moldboard, whereas the share of the Western plow has a quite different character from its moldboard which is more unstable than the moldboard of the Japanese plow but seems to be superior to it in regard to the inversion of furrow slice.
