The soil is the most important factor in crop development. Seedbed preparation consists in breaking up clods, mixing the organic matter into the soil, and then levelling and tamping it all. This procedure creates a favourable environment for micro-organisms and root development which enable the plant to draw the nutrients it needs to develop. Reducing the number of passes is also vital, both agronomically, by limiting compaction, and economically, by reducing costs. Therefore, farmers need versatile tools that can till the land and sow the seeds in a short time. With fast working speeds and the choice of solo operations or combination with a cereal seeding bar, power harrows in the HR RCS range will allow you to meet these objectives. It is also possible to combine a precision seeding bar with the 4.5 and 6 metre versions.

A modular concept: work solo or in combination

##NewLine##A grain-crop seeding combination at work, composed of an HR 4530 RCS power harrow and a BTFR 4530 seeding bar

A specially designed frame to fit a seeding bar

KUHN RCS power harrow models are designed to be fitted with a seeding bar. The seeding bar fits onto the power harrow's roller frame. This configuration places the centre of gravity closer to the tractor, limits overhang, and reduces the power requirement for lifting the combination. It also improves work quality by providing high stability, excellent ground following, and a constant seeding depth, irrespective of the power harrow's working depth.

Can work in combination with a cereal or precision seeding bar

The HR 4530 RCS power harrow is compatible with BTFR 4520 / 4530 seeding bars and the 6-row KOSMA CSM precision coulter bar which works at a width of 4.5 metres. The 6-metre-wide HR 6040 RCS is designed to be coupled to BTFR 6010 / 6020 / 6030 seeding bars for cereal or the 8-row KOSMA CSM 8 coulter bar for maize

Optimum seedbed preparation

Hydraulic power-harrow and levelling-bar height adjustment

Continuous adjustment to working conditions

The working depth of the power harrow and the height of the levelling bar need to be easy to adjust, and instantly, from the tractor cab, to adapt to working conditions in real time (dry or wet conditions, soil heaviness, etc.) and produce the best results. That's why working-depth and levelling-bar adjustment are hydraulic as standard.

So many possibilities for efficient crumbling and tamping

Power harrows in the HR RCS range are equipped with carbide-coated DURAKUHN tines, as standard, for higher resistance to impacts and wear. Thanks to the FAST-FIT tine attachment system, you save time when replacing them. They are compatible with MEGAPACKER (Ø 590 mm) and STEELLINER (Ø 550 mm) rollers. The MEGAPACKER is recommended for light, chalky, chalky-clay and silt-clay soils. The STEELLINER is effective for precision tamping in each seeding line. In addition, the HR 6040 RCS power harrow can be equipped with the PACKLINER roller (Ø 592 mm). The large diameters of these rollers gives them excellent rotation and bearing capacity.

Work faster while staying in control

Controlled power

HR 4030 RCS, HR 4530 RCS, and HR 5030 RCS power harrows, with working widths from 4 to 5 m, are designed for tractors from 300 to 350 hp maximum power (depending on the model). The HR 6040 RCS works at a width of 6 m with high-powered tractors up to 460 hp, ensuring high working speeds. An oil cooler protects the central gearbox against overheating. The oil cooler is insensitive to dust and lengthens the life of the oil, so oil changes are less frequent. The integrated pump is activated automatically with the PTO so the driver does not need to think about it! The entire drive train is protected against overloads by one (or two) torque limiters (depending on the model).

A robust rotor, with no play and no maintenance

The design of the high-strength steel housing and the lubed-for-life gears and bearings make KUHN maintenance-free rotors highly resistant. The rounded shape of the forged and heat-treated steel gearwheels eliminates any overhang on the roller bearings. These large roller bearings are secured by a calibrated spacer. They are aligned in the housing and their perfect fitting protects them against wear and deformation. The conical centring of the tine holder prevents any play in the splines.

STEELLINER furrow-opening roller for KUHN power harrow

Furrow-opening roller for the precise tamping of each seeding line

Power harrows in the HR 1040 R range are also compatible with the STEELLINER roller. With its overall diameter of 500 mm, this roller offers very good rolling and carrying capacities. It is adapted to difficult and wet conditions and provides excellent crumbling capacity on dry and hard soils.

KTS 20 monitoring terminal as standard

Installed in the cabin, the KTS 20 monitoring terminal continuously monitors the temperature as well as the rotation of the three machine gearboxes. As soon as a torque limiter or an overheat sensor is activated, the driver can react rapidly and avoid a failure. This represents savings of nearly 900 €/day: the equivalent of the loss of revenue due to a one-days downtime.
