Study on balance of the power tiller

Abstract

Owing to know the stability of power tiller, we must be research the position of centre of the gravity, at the beginning.
If we have inclined the machine until it shall be balanced, in the front and in the side, we can surely get the center of gravity.
The balancing point in the side, thats showing Fig. 1 be able to express in the formula of Y=A sin X+B.
In this formula, Y is the weight that is acting on the handle, X is the plate angle of the tiller, A shows the inclination of the formula, and B shows the weight of handle on the plate angle is in parallel with the horizon.
In several power tillers, A of the Japanese tiller is largest than the other, therefore this tiller is difficult to drive than the other machine on the slope.
When designning the power tiller, we must be decide the balancing weight of each parts as near as the formula that is most suitable on the stability, Y=1.2 sin X.
