TESTING OF MULTIPURPOSE EQUIPMENT FOR SIMULTANEOUS PRIMARY AND SECONDARY SOIL TILLAGE PREPARATION (Atena Editora)

Abstract

Soil resource conservation in crop establishment is a global issue that has gained much interest in a recent year, due to the growing demand for food in the agricultural sector. Despite the above, there is a current trend in the different production systems oriented to extensive and intensive use of the soil, which has increased not only its costs (mainly fossil fuel consumption), but also its physical, chemical and biological degradation to the detriment of its sustainability and sustainability. Faced with this problem and the lack of technically appropriate equipment, it is important to generate agricultural practices and technological innovations that, in addition to being efficient, can be quickly adopted by producers, given their competitive advantages. The objective of this research was to present an integral technological alternative to reduce fuel consumption and effective operation time, through a Multipurpose prototype that performs the simultaneous preparation of primary tillage (plowing) and secondary tillage (harrowing) of the soil, using medium power tractors. The Multipurpose is a mechanical equipment made up of three sections: (chisel plow + harrow + lump breaker), which are combined for the simultaneous preparation of primary and secondary tillage of the soil. The first section has a plow with three semi-straight chisels with narrow tips (two shallow and one deep with flap coupling), the second section has a harrow with 12 discs and finally, it uses a lump breaker. The working width of the equipment is 1.2 m and it is 3.2 m long. The equipment requires a minimum of an 80-horsepower tractor and is coupled to the tractor's three-point hitch. This technology performs soil conditioning for crop production in a single step.
