Effect of the Center of Gravity and its magnitude of Plow on the Plowing

Abstract

We examined the location of center of gravity and its weight for many plows, and analysed the relationship between the center of gravity and plowing condition that a plow had the best stability.
We found the formula between the center of gravity and the draft resistance. If this formula is permited, a plow gives the best stability and the easiest draft, and then a plow has the self-controlled action in the certain extent of working depth.
When we wish to increase working depth, we can do it by putting on weight to the location of center of gravity which is lied on the vertical plane, containing the true line of draft.
Draft resistance and coefficient of resistance of a plow that was added weight, was smaller than that which was increased working depth without loading.
