1. OPERATIONAL AND ENERGY PERFORMANCE OF 250 kW DOUBLE WHEELED VERSUS RUBBER HALF-TRACKED TRACTORS IN THE SOYBEAN SOWING
ABSTRACT The technological innovation in agriculture seeks to improve the performance of mechanized assemblies and, currently, rubber half-tracks are a valuable solution for agricultural tractors, combining traction performance and less soil compaction. The objective of the experiment was to evaluate the operational and energy performance of double wheeled v

3. ESTUDO DE TRAFEGABILIDADE APLICADO A VEÍCULOS DE RODA EM TRANSPORTE E TRAÇÃO / TRAFFICABILITY STUDY APPLIED TO WHEELED VEHICLES IN TRANSPORT AND TRACTION
The ability of vehicles to traverse soft soils is an important aspect of their performance. The geological, climate and topography diversity originated, in Rio Grande do Sul, extensive areas of hydromorphic clay soils, as example, Planssoils and Gleissoils. When saturated of water, these soft soils present low loads support, difficult agricultural machinery

4. Desenvolvimento de um sistema de aquisiÃÃo e armazenamento de dados microcontrolado
The data acquisition systems are present in many studies, cooperating on collection, storage and analyses of data. On farming field, these systems are used in experiments of agricultural machines, soil characteristics study, as well as in other applications where data collection by sensors is needed. In the present study, a data acquisition system was develo

5. Empirical model of depreciation for tractors of wheels. / Modelo empírico de depreciação para tratores agrícolas de rodas.
The depreciation of wheeled tractors is an important component of the fixed cost. The right determination of this parameter is vital to determine the machinery cost during its useful life. Several methods are proposed in order to estimate tractor depreciation with more than a year of use: linear, decreasing balance, sum of the years digit, fund of capital
