Each McCormick tractor reflects the passion and dedication of those involved in designing testing and producing this superb range of tractors. The new X7 VT-Drive tractors offer the ultimate in style, technology, operator comfort and productivity. Five models in the range are all powered by the new Betapower Fuel Efficiency four-and six-cylinder turbo engines with multivalve technology and common rail injection system. These engines meet Tier 4 Interim emission regulations using the SCR system, an exhaust gas after-treatment technology that reduces exhaust emission without compromising engine performance. The X7 models with VT-Drive continuously variable transmission feature five engines with power ratings of 136, 150 and 166 hp for the four cylinder and of 172 and 181 hp for the six cylinder. The VT-Drive transmission is a continuously variable transmission (CVT) that provides an infinite number of speed ratios from zero to the maximum speed permitted in the country of use. Both transmissions feature a left-hand steering-column power shuttle and are controlled electronically via pushbuttons located on the multi-function armrest.
