The company states that 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.
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.
In addition to the V-frame concept, Krone notes that the 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 company says that this protects both the machine and the grass, while also minimising the turning time at the headland.
Fifteen tine arms on each rotor, each with four tines on the front and five 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.
Krone states that 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.
