The new Valtra tractors of the S series appear in a new design and with more power. With 280 to 420 hp, the Series S models are the largest tractors that Valtra builds. The machines are built with the new 8.4 l AGCO Power engine and the ML 260 continuously variable transmission. The tractors have a 5 percent lower speed and are said to save up to 10 percent fuel compared to previous models. The S series comes onto the market without exhaust gas recirculation (EGR) and with a reinforced rear axle and PTO. A special feature of the series is the equipment option with the TwinTrac reversing device. Only a few tractors in this performance class offer this option.
