Constructional characteristics of the agricultural tractors at the beginning of the 21st century
Through implementation of new technological innovations from the area of the motor vehicles, the agriculture tractor became high sophisticated vehicle-machine. Tractor engines are equipped with the common-rail fuel injection system, four valves per cylinder and variable geometry turbocharger, and fulfil rigorous ecological standards regarding the air pollution. Continuously variable transmission enables selection of the optimal transmission speed according to working conditions. Besides very accurate adjustment of three point-hitch drawbar, electro-hydraulic control system enables more additional functions. Significant improvement was obtained at ergonomics of operator’ s working place conditions. Computer control systems are going to take over more and more functions, not only in operating, but also in tractor diagnostics. The utilization of recycling materials, bio-fuel and biodegradable lubricants represent high level of ecological manufacturing as well as tractor operating level.
