6-7 Series T4i V-Shift: all-round innovation
All tractors of the 6-7 Series V-Shift feature a ZF continuously-variable transmission with four speed ranges. This tractor family comprises three four-cylinder models, the 6.145, 6.160 and 6.175 with power ratings of 147, 160 and 176 hp, and two six-cylinder models, the 7.175 and 7.190 delivering power ratings of 181 and 195 hp with the Power Plus system. All models are powered by FPT NEF engines with SCR catalytic converter that meet the Tier 4 Interim emission regulations. The V-Shift 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. The electro hydraulically-engaged rear PTO features an exchangeable shaft providing 6 or 21 splines and offers four speeds 540/540E/1000/1000E rpm. The electronic control of the PTO always ensures smooth and modulated implement start-up. The system also incorporates PTO headland management to eliminate implement drive line damage when raising the machine. The 6 and 7 models with V-Shift transmission are available with closed-centre hydraulic system with variable-displacement pump. The electronically-controlled rear hitch with draft sensing on the lower links provides a maximum lift capacity of 9300 Kg and allows a precise control of the implement. Also included is a Ride Control system to help protect the implement and reduce shock loadings on the tractor during transport.
