4-Link axle for exceptional maneuverability (780/760). This industry first, developed and patented by CLAAS, sets new standards by ensuring unrestricted mobility with tires up to 30 in (1.65 m) in height. And it provides exceptional stability and load bearing capability. Unlike a conventional pivoting axle that pivots from a center suspension point, the new 4-link axle is suspended at two points, and not only pivots up and down, it also shifts laterally for improved terrain compensation and ease in turning. 4-Link POWER TRAC (780/760). CLAAS POWER TRAC provides greater traction thanks to the hydrostatic drive on the rear axle.
With the ability to engage POWER TRAC while moving, this adjustable rear axle reduces fuel consumption due to greater efficiencies. 46
