Studies on the Draft of Implements mounted on Small Tractors (II)

Trial Made of Device for Measuring Three Components and Three Moments of Draft

Abstract

To study the draft of implements mounted on small tractors, the authors made a device for measuring three components and three moments of draft.
An implement is attached to a frame that is supported on the device by twelve small plates on which the electric resistance strain gages are sticked.
Each gage is connected to a pen writing oscillograph, which also records time and distance on a strip-chart.
By this device we can know three components, they are horizontal, vertical and side forces, and three moments.
