KUHN Farm Machinery has launched a new folding 4.5m HR 4530 RCS power harrow that can be equipped with a choice of new seeding units for different crops and full hydraulic adjustment, offering flexibility for seedbed preparation and drilling in a variety of conditions.
The new HR 4530 RCS replaces the HR 4504 DR and is the smallest model in KUHN’s range of folding power harrows. It is suited to tractors up to 300hp and features hydraulic adjustment of seeding depth and levelling bar as standard.
The central Duplex gearbox is equipped with an automatic oil cooler to prevent overheating, and a torque limiter protects the entire driveline from overloading. The gearbox also features changeable gearwheels to alter the speed of the rotors to the working conditions.
A choice of two rollers are compatible with the HR 4530 RCS – a 550mm STEELLINER and a larger diameter 590mm MEGAPACKER – depending on the desired finish and soil type. Fast-fit DURAKUHN tines with a carbide coating are standard, with optional DURAKARB tines offering a harder wearing tungsten carbide plate.
The modular design allows the choice of two coulter bars to be fixed on the roller frame of the HR 4530 RCS. This maintains a close centre of gravity to the tractor to reduce the rear lift requirement, and a constant seeding depth can be maintained regardless of the power harrow working depth.
A new BTFR 4530 cereal coulter bar offers row spacings of 12.5cm (36 rows) or 15cm (30 rows). It features KUHN’s SEEDFLEX seeding units, with offset double discs mounted on a parallelogram linkage for precise control of the seeding depth, and 35mm spacing between the two rows allowing trash or clay soils to flow through. VISTAFLOW valves are optional on all rows to improve seed blockage monitoring and allow universal tramlining, which establishes tramlines by shutting individual rows, even when the working widths of the drill and sprayer aren’t compatible.
Users after a compatible toolbar for maize sowing can chose the new KOSMA CSM precision seeding bar that has six rows across the 4.5m width, spaced at 75cm. This new combination is 25cm shorter than a conventional setup, which brings the centre of gravity closer to the tractor.
KUHN’s existing TF 1512 Isobus front tank can be used with the above seeding combinations as either a seed delivery unit for the BTFR 4530, or fertiliser hopper for the KOSMA CSM. As standard, the TF 1512 is a 1,500-litre tank, but a 500-litre extension can be added.
