The variants available for tractor drives are almost as diverse as their possible applications. In addition to the conventional hydraulic drive concepts, Linde has a special option on the market: the compact K-02 unit. The variable-displacement pump and the motor are mounted back-to-back within a common housing, thus eliminating the need for hoses. The K-02 Series from Linde is available in two basic variants: as a fully hydrostatic drive, combined in a single unit, or as the hydrostatic branch of a power-split mechanical CVT gearbox.

The inline design, featuring a hollow shaft, enables direct torque transmission from the prime mover to the PTO shaft. For compact tractors, the K 75-02 therefore offers stepless drive technology for the propel drive and direct power transmission for auxiliary drives.

The example shows the K 75-02 as a component of a powersplit gearbox. It is fitted directly within the gearbox casing. The power of the diesel engine is split at the input. One part is linked by a direct mechanical connection to the annular gear of a planetary gearbox. The K-02 is positioned in the second path as a variable unit and drives the sun gear as required. The power is transmitted as required; the speed can be precisely controlled. The sensitive hydrostatic system keeps the tractor under control on hills, preventing inadvertent rolling away and permitting smooth and gentle starting. The high conversion capability ensures that virtually any load situation can be mastered at low diesel engine speed.
