abstract
The development and construction of a mini-soil bin was addressed in order to study in laboratory the mechanical behaviour of agricultural soils handled under different implements. The implement was attached to the cylinder rod through a dynamometer (to measure the horizontal and vertical forces and their momentum), and its operating speed was controlled by a flow regulating valve (variable orifice). The mini-bin consisted of two structures: one of them held the electro-hydraulic group and the other a double-acting hydraulic cylinder which pulled the working device. The soil bin was placed on the latter.
