The hydraulic reach mower of the TKD series have been designed for a highly professional use. Consequently the quality and reliability of each single component chosen reflects the need to serve a” professional “use. One example is the closed circuit piston hydraulic system, the coupling of the pumps with a high torque worm gearbox; cemented and hardened pins and bushes, and abrasion resistant hydraulic pipes. The TKD series features a movable “parallelogram” mechanism which can hydraulically move the second arm 245 cm forward and consequently the position of the flail head. This feature allows the professional operator to maneuver the machine without having to turn around and look backwards, thus providing considerable comfort to the operator. The position of the pivoting bracket moves the center of gravity of the machine in an optimal position for greater stability and better driving comfort.
