With a maximum working width of 15.70m, the Swadro TC1570 four-rotor centre-delivery rake is said to be an ideal fit for CTF systems.

Sitting above the existing four-rotor TC1370, the V-frame concept on the newcomer is an adapted version from the six-rotor TC2000. Operated via an ISObus terminal or in combination with an ISObus joystick, working width is adjusted by the two front rotor arms.

With 15 tine arms on all four rotors, the mechanical driveline allows the front two rotors to rotate about 25% faster than the rear ones, which the company reckons ensures optimum forage flow inside the machine and tangle-free, box-shaped swaths. Swath width is hydraulically adjusted via the two rear rotors from 1.40-2.90m.

The main frame lowers hydraulically to reduce the transport height to below 4.0m without having to fold or remove tine arms. The transport chassis is equipped with 710/40 R22.5 tyres as standard (optional 800/35 R22.5). In field stability is improved by the wide 16 x 9.50-8 four-wheel rotor chassis tyres (optional six-wheel rotor chassis) and the 15/55-17 support wheels on the two front arms.

The TC1370 is one of the new machines that will be on display on the Krone stand at Agritechnica in November.

Electric height adjustment allows the rotors to be adjusted individually or simultaneously, and two self-selectable heights can be saved on the terminal and activated at the touch of a button.

On headlands, the rotors can be set to lift just over existing swaths. Lift delay of the rear rotors is also adjustable, and the automatic Soft-Down mechanism slows the speed of lowering just before the rotors touch down. Section control is also available to lift/lower the rotors automatically using GPS.
