KUHN's new range of HR power harrows has a model to suit every condition as well as options adapted to your requirements. The HR 1020, 1030 & 1040 series power harrows with working widths of 3 to 4,5 m, can work in solo or in combination with a seed drill. The HR 1040 series power harrows are ideal for high-powered tractors up to 320 hp. Hydraulic adjustments make your job easier, and as work output is one of our priorities too, our power harrows have been developed to extremely high standards, to ensure you are able to work non-stop.

A perfect seedbed in all conditions

The attachment components of the VENTA seed drill are fitted to the packer frame of the HR power harrow

The seed drill mounted onto the roller frame

When coupled with a seeding combination, the power harrow depth and the seeding depth work completely independantly of each other. This is because the drill in mounted on the roller frame. This also increases stability, and guarantees accurate seed placement. These power harrows are designed to work with both pneumatic and mechanical seed drills.

Tines, rotors and levelling bar adapted to your conditions

The specific design of the tine helps create a fine tilth with a working depth of down to 20 cm. The HR 1040 series features 335 mm tines to perform in the most challenging conditions. Duplex gearboxes make it possible to adapt rotor speed to working conditions. Speed can vary between 255 and 539 rpm for the 1040 series to achieve excellent seeding quality in very difficult conditions. Depending on the series, depth and levelling-bar position are hydraulically adjustable from the cab to adjust the machine on the move.

HR 1020-1030-1040 power harrows with adustable levelling bar

Perfect levelling between passes

Long and deep profiled side deflectors ensure a perfect finish between two passes. They are quick and easy to adjust with spring safety and double-arm attachment for optimum hold.

The benchmark for reliability

Central gearbox with oil cooling system on HR 1040

A gearbox with a difference

The central gearbox is equipped with an oil cooling system on 1040 series machines. The integrated pump and additional oil tank cools the oil before re-injecting it into the gearbox. With greater oil cooling capacity, the horsepower rating increases.

A linkage adapted to all tractors

The standard coupling type is category 2 and 3 with the possibility of adapting to large tractors with cat. 4 quick hitch. Two connection points are possiblr, to position the machine closer to the tractor if required. The central gearbox is set back on the machine to reduce the angle of the PTO when turning on the headland.

HR Power Harrows and the linkage possibilities

FAST-FIT blades as standard

The standard tines are equipped with a quick release system, a heavy duty protected linch pin holds the locking mechanism in place, simple remove it, the locking pins will drop down and the tines can slide out. The tines are straight with lengths of 315 mm (1020 and 1030 series) and 335 mm (1040 series).

Reliable rotor: copied but never equalled

The perfect rotor design

The powerful rotor driveline is fully protected by a rigid gear case. The casing, bearings and tine holders form a compact and highly robust unit reducing torsion stress on the housing. The small distance between the casing and the blade holders prevents stones from getting jammed and channels soil-flow through the tines. The rotor has a maintenance-free and highly rigid trough. There is no gearwheel overhang thanks to convex gearwheels in forged steel which run in line with the upper bearings. The bearings require no maintenance; they are perfectly aligned in the one piece rotor drive casing so are not subject to distortion. Reinforced sealing is ensured with a cassette seal on HR models. Conical centring of blade holders (KUHN patent) prevents play on the splines. The blade holders are oval to prevent stones from getting jammed and facilitate their flow-through the machine.

Equipment

A wide range of equipment is available such as track eradicators and stone deflectors. The wide choice of rollers will meet all of your requirements.

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.

Recommended for light soils, limestone, clayey-limestone and clay-loam soi...

Very large diameter (590 mm) packer roller consolidates the land very well in light soils.

Track eradicator available as option on KUHN power harrows

To loosen the soil compacted by the tractor wheels

The track eradicators available as optional equipment are designed to loosen the compacted ground where the tractor wheels have passed. They are adjustable in height. Depending on the working conditions and the amount of stones present in your fields, you can choose between a safety system with a traction bolt or springs.
