Seedbed preparation tools must perform high work output while operating smoothly and non-stop for as long as necessary. The power harrows are the result of an outstanding quality of workmanship. To better understand this, just take a look inside the machine: intelligent design of the rotor drive and robustness of the gearbox ensuring maximum service life as well as minimal operating costs and maintenance.

High outputs in short working windows

Central gearbox equipped with an oil cooling system and integrated pump.

The perfect combination with powerful tractors

The HR 1040 R foldable power harrows are designed for intensive use with high-powered tractors. The HR 6040 R power harrow can be used with tractors up to 460 hp, whereas HR 7040 R and HR 8040 R models can accomodate 480 and 500 hp respectfully. The central gearbox is equipped with an oil cooling system with an integrated pump. The synthetic oil used withstands temperatures higher than standard oil.

Compatibility with several hitch types

The HR 1040 R power harrows are compatible with cat. 3, 4 and 4N hitches. They can also be coupled to a cat 4 quick hitch. The primary PTO is reinforced and the secondary PTOs are fitted with cam-type cut-out clutches so each side is protected independantly. The central gearbox is positioned towards the rear to increase the length of the pto shaft and reduce working angles: an asset for tractors equipped with large-diameter wheels.

HR 1040 R power harrows are widely compatible with different couplings

HR 6040 RCS and BTFR 6030: a modular concept

Designed to work with the new BTFR 6030 seeding bar, the HR 6040 RCS power harrow is suited for tractors of up to 460 hp. The working depth of the levelling bar can be adjusted hydraulically from the tractor cab. For increased flexibility, the power harrow can also be used in solo for seedbed preparation. As with all HR 1040 R models, the HR 6040 RCS benefits from a removable transport carriage which features two large-diameter wheels that are easily and quickly removed without tools. This transport carriage is essential for safe road transport.

High work output are ensured with the HR 6040 RCS and BTFR 6030 seeding bar combination

Robust and reliable

Cross-section view of the KUHN power harrow rotor

A rotor sometimes copied never equalled

The streamlined casing designed made from high tensile steel containing semi-fluid grease (Sprockets and bearings are lubricated for life) provides a highly rigid, maintenance-free trough. The sprockets, in forged, heat-treated steel guarantee a drivline which can stand the test of time. The concave profile of the sprockets ensure that they run in line with the bearings and give a stable driveline across the width of the machine. The perfect bearing pre-tension protects them from wear and distortion. There's also reinforced seals and no play on the splines thanks to the conical centring of the tine holder (KUHN patent).

FAST-FIT DURAKUHN blades as standard

For increased longevity, KUHN power harrows are delivered as standard with tungsten carbid coated blades. These DURAKUHN blades are made to last.

A perfectly prepared seedbed

Perfect adaptation to varying soil conditions thanks to the hydraulic settings.

Perfect adaptation to varying ground conditions

Within the same field, the soil conditions may vary greatly. To achieve a higher quality of work, the machine must be able to be adjusted easily and instantly. The HR 1040 R series power harrows allow for the hydraulic adjustment of both the working depth and the levelling bar from the cab, allowing the operator to finely adjust the level of finish on the move.

A perfect finish with the levelling bar

The levelling bar has three angle possibilities for precise adjustment of the crumbling intensity. Angled forwards or vertically, the levelling bar recycles the soil for intensive work in very heavy soils. Tilted rearwards, the levelling bar allows for a greater soil flow in lighter soils. This flexibility also improves the management of the fuel consumption. Furthermore, the levelling bar is mounted on the roller frame so your levelling bar is always set at the same height in relation to the ground level.

The levelling bar on HR 1040R offers three setting positions for a perfect finish.

Two halves for complete work quality

You can choose between the rigid or floating working position. In floating position, both halves can be raised or lowered individually over a range of 2.5° for improved adaptation to ground contours. A long side deflector adjustable in height ensures perfect finish after each passage. The positioning of the two half-harrows as close as possible to each other is appropriate. This close proximity prevents formation of ridges non crumbled by the half-harrows. The standard front share positioned in front of the gap between the two half-harrows ensures an impeccable result over the whole working width.

Equipment

A wide choice of rollers and equipment to satisfy all conditions.

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.

STEELLINER furrow-opening roller for KUHN power harrow

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

With its overall diameter of 500 mm on HRBs and 550 mm on HRs, the STEELLINER roller offers very good rolling and carrying capacities. It is adapted to difficult and wet conditions and provides an 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.

A flexible roller

Its large diameter of 535 mm reduces rolling resistance. It can easily be combined with seed drills or planters. Standard hard coated scrapers increase service life, reduce maintenance and improve roller cleaning in sticky soils.

MAXICRUMBLER roller for KUHN power harrows

A light roller

This roller is ideal for spring and summer soil preparation. It requires low traction power and is economical. The MAXICRUMBLER roller (520 mm diameter) limits soil accumulation and works well in stony soils.

Work in stony conditions

V-shaped stone deflectors can be fitted between two rotors to stop the stones from becoming jammed.

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.

Carrying frame

The HR 1040 R power harrows fold hydraulically and lock in transport position. A standard carrying frame fitted with twin pivoting wheels of large diameter provide a high comfort of driving on roads. No braking system is required and even transport with medium-power tractors is compliant with road regulation.
