Design and performance of an adjustable three-point hitch dynamometer

摘要: Mounted implements necessitate the use of a three-point hitch dynamometer to measure forces between tractor and implements. In this work, an adjustable was designed fit most (standard non-standard) available in Jordan. The consists three telescoping beams connected central T-shaped box. system provides variable width height satisfy wide range implement dimensions. Strain gages attached cantilever were Wheatstone bridge such manner that only draft force is measured. calibrated several field tests conducted required pull chisel plow Jordanian clay loam soil at various depths speeds. Different sets strain can be arranged so lateral or vertical
