BACKGROUND OF THE INVENTION [ 2] There are currently a considerable variety of motor vehicles designed especially for use in the agricultural field. Generally speaking, these machines are based on a propulsion engine, usually diesel, having a variety of means to enable their front region to receive different agricultural implements. Thus, the same motor vehicle is able to perform different jobs for a wide range of crops, such as: harvest, collection, product cleaning processes and/or other services. This is seen in documents: PI 0904513-9 A2 (Br), PI 7702491-5 Bl (Br), PI 7902586-2 (Br) and PI 7702491-5 (Br). [3] There is no doubt that some existing motor vehicles have the means for coupling different agricultural implements and performing a considerable variety of jobs with different crops. However, the existing motor vehicles are usually very complex machines, intended for large agricultural producers, and this kind of equipment is often inviable for some agricultural producers, especially those that are medium and smaller-sized. What is needed therefore is a simplified form of a compact agricultural motor 2 vehicle, having the ability to attach and interchange a variety of agricultural implements to the vehicle, such that it is still able to perform a variety of different tasks, such as the harvesting, collection and processing of different kinds of grains and cereals. Such an agricultural motor vehicle is ideal for use by large, medium-sized and small producers. SUMMARY OF THE INVENTION [ 4] The present invention refers to an agricultural motor vehicle designed to receive agricultural implements at its front part, with applied technical and functional enhancements allowing for different work implements to be coupled to the set. The motor vehicle of the present invention has an internal combustion engine, preferably with a diesel cycle, interconnected with hydraulic pumps with different capacities which activate various hydraulic cylinders and engines, so that all parts of the coupled implement and other implements integrated with the motor vehicle are activated by the same hydraulic system. This allows for the harvest, collection and processing of different kinds of grains and cereals, such as peanuts, soybeans, beans and others. [SJ The present Application seeks to provide a compact motor vehicle based on a combustion engine, but having a simplified form to make use of the force produced by it. For this purpose, it is interconnected to hydraulic pumps which, also activate various hydraulic cylinders and engines, and therefore, all sets forming the motor vehicle are activated by the same system, allowing the vehicle to perform a variety 3 of jobs, such as the harvesting, collection and processing of different kinds of grains and cereals. [6] The present invention also has a compact chassis, able to join all functional parts of the set, not only those which are permanent parts of the motor vehicle, but also those implements which are interchangeably attached and removed to perform different services, making the set ideal for use by large, medium-sized and small producers.
