Abstract

Abstract The paper describes the design and construction of a torsional shearing device intended for field measurement of the mechanical properties of the topsoil. The device is rigidly mounted on an agricultural tractor and is powered from its hydraulic and electric system. It is provided with an electric system that controls the device through the test cycle. The data recording system is described and various problems involved with the use of the device are discussed.
