Speed and smoothness of shifting in the powershift transmission fitted to Case-IH’s Quadtrac four-tracked tractors has been improved, and whether the operator chooses to use the transmission in manual, skip or automatic mode, the time taken to shift from 1st to 16th gear has been cut by around 20%. Case-IH calculates these latest improvements save between 2% and 5% of engine power. At the same time, forward/reverse shuttle shift response has been made faster and smoother, which is claimed to result in a 38% increase in shuttling speed, and reduces the time spent manoeuvring on the headland. Other Quadtrac updates include the new Advanced Steering System, which reduces the number of steering wheel revolutions required to turn between full lock positions from six to four, while also cutting the effort required to make steering turns. When the tractor exceeds 35km/hr, the system switches from field to road mode, indicated on the A-post information display, and provides increased steering sensitivity during high-speed road travel. Meanwhile, a new AccuGuide Advanced Line Acquisition system improves engagement of automatic steering when entering a new bout, getting the tractor on line faster but more smoothly, reducing the risk of overlaps or misses during headland turns. Finally, new Quadtracs now comes as standard with an automatic differential lock (similar to that already used in Magnum tractors), a new 360-degree LED lighting package and split rear view mirrors.
