General working principles for agricultural tractor with ploughing equipment

Abstract

Agricultural machines are considered part of special mechanical equipments category intended to perform mechanized works in farmlands, in order to obtain optimal harvests. The continuous development of these equipments was mainly aimed at evolutions of specific technological processes, constant increasing of speed in operation mode and also increasing of engine power. In order to well perform the proposed technological process, they should have high resources of reliability, durability and stability in execution in spite of the external conditions in which their operation is carried out. This paper performs a constructive and functional description for agricultural tractors equipped with plowing working equipment. Also it is described the hydraulic suspension system by means of which the plowing device can be raised for transport or lowered to the working position. For instance, it was chosen the three-point articulated model for the suspension system used because it is the most widely used on the most constructive pattern of agricultural tractors.
