World’s largest four-rotor rake – The NEW Krone Swadro TC1570


The New Krone Swadro TC 1570 with unique V-frame concept impresses with high acreage output, extremely quiet running and maximum operator comfort.

The new Swadro TC 1570 is centered around the well-proven V-frame concept adapted from the world’s largest centre 6-rotor rake, the Swadro TC 2000. This concept gives the machine a flexible working width of up to 15.7m and makes it extremely stable and smooth running. Using the new intuitive user interface, the entire machine can be operated from the tractor cab via an ISOBUS-compatible terminal or in combination with an ISOBUS joystick.



Maximum flexibility and stability

The working width of the four-rotor rake centre delivery can be variably adjusted from 11m up to 15.7m via the front rotors guided by the V-outriggers. The two V-outriggers can be retracted and extended independently of each other ensuring field corners and obstacles can also be raked around effortlessly. The outriggers are each supported by a wheel in the front area enabling quiet running, especially at high speeds and during fast turning on the headland. Hydraulically adjustable outrigger arms of the rear rotors, mean that swaths can be produced in a width of 1.40m to 2.90m.



Equipped to the maximum

In addition to the V-frame concept, integrated vibration damping also ensures that the machine runs smoothly in the headland position. A Soft–Down automatic lowering mechanism ensures that the outrigger arms are decelerated just before the rotors touch down, ensuring that they land gently on the ground. This protects both the machine and the grass, while also minimising the turning time at the headland.

15 tine arms on each rotor, each with four tines on the front and 5 tines on the rear rotors enable work quality to be maintained at higher driving speeds. With Electrical rotor height adjustment, the height of each rotor can be adjusted individually, or all rotors can be adjusted simultaneously via the operating terminal to suit the working conditions.

The Swadro TC 1570 is equipped with a category II/III pendulum-suspended two-point hitch. This reliably compensates for uneven ground and gives the rake enormous manoeuvrability thanks to its large steering angle.



Equipment without compromise

The hydraulic rotor relief integrated in the lifting cylinders ensures optimum bearing pressure of the rotors. This can be set separately for the front and rear rotors via the terminal, even while driving. When adjusting the working width or swath width, the relief pressure is automatically adjusted by an active control system so that the rotors are always evenly relieved. Together with the gimbal rotor suspension pulled by the outrigger arm, the rotor adjusts optimally to the ground contours under all conditions – this protects the grass and prevents dirt from entering the crops.

The lifting heights of the rotors can also be set via the operating terminal. At the headland, for example, they only lift as far as is necessary so as not to destroy existing swaths. The lift delay of the rear rotors with respect to the front rotors can also be adjusted from the cab. You can choose between a time-dependent or path-dependent delay. Lifting and lowering can be controlled even more efficiently using the Section Control partial width switching. In doing so, the rotors are lifted and lowered fully automatically with the aid of GPS positioning.

The main frame of the rake is hydraulically adjustable to allow for a transport height under 4m without the need to fold down the tine arms.



Conclusion: With its unique V-frame concept, advanced technology and the highest level of operator comfort, combined with all the familiar Krone features such as Krone Jet Effect for lift up and set down of the rotors without dragging dirt into the crop, a lubricated for life and maintenance free rotor gearbox, Duramax cam-track and one piece tine arm – the Swadro TC 1570 achieves a previously unattained level of performance in the four-rotor rake class.
