The H series is the robust medium-sized power harrow for effective operation in most conditions. By using a double bending sandwich section for the trough, it has been possible to increase its strength, making it self-supporting without increasing the weight whilst keeping a clean and tidy design. Main features like the rotor distance of 25cm, the double conical bearing, heavy-duty headstock and the modular tine carrier have been considered too.
Two profiled 6mm plates ensuring precise rotor spacing, high bending resistance of the 140 x 400mm trough. Tine shaft of 50mm with two large conical bearings, Ø 45mm and Ø 50mm with a distance of 55mm and 40mm gears and an ample clearance of 95mm between the trough bottom and the tine holder ensure good soil flow and allow surface residues to pass easily through the machine.
|Model||Working width||No. of rotors/tines||Weight with packer roller|
|H series||3.0m||12/24||1590 kg|
|H series||3.5m||14/28||1770 kg|
|H series||4.0m||16/32||1920 kg|
For optimum performance in difficult soil conditions, the robust and self-supporting trough design provides a large clearance between the tine holder and trough bottom. This allows large amounts of residues and stones to pass freely without blocking and provides excellent results in mulch conditions.

All models can be fitted with Standard and Active tines as well as with the proven Quick-Fit system to meet customer demand for efficiency.
The active tines ensure optimum penetration in hard or not cultivated soil. The tine, due to its shape, pulls itself into the ground. This gives a constant working depth and also prevents the machine from lifting out of the ground in hard dry soil conditions. In addition, it creates additional re-compaction at the packer roller. The active tine lifts the material and pushes it in front of the power harrow. This gives an optimum levelling effect even in tractor tracks. In mulch conditions the active tines can work directly into stubble and hard soil. The special shape of the tines keeps residues on the surface and this gives a big advantage against erosion.
Helical tine positioning
The tines are arranged in varying angle positions in order to prevent damage caused by stones and ensure even levelling. 4 rotors per meter and the helical tine positioning reduce the peak loads on the driveline which results in smoother running and less fuel consumption. All gears are hardened in the trough for a long lifetime.
The quick-fit tines for easy replacement and carbide tines for a longer lifetime and minimum wearing are available as an option.
Re-consolidation for a stable soil structure
Rollers ensure re-cmpaction of the soil as final step of the optimum seedbed preparation. By reducing soil porosity and limiting evaporation, all plants will have the same access to nutrients, moisture and light. This will give the crop a good start for a perfect growth and high yields.
The right rollers for all types of soil and conditions:
Actipack ø560mm – 205 kg/m
Cracker Packer ø550mm – 200kg/m
Tooth Packer roller ø575mm – 160kg/m
Cage roller ø550mm – 90kg/m
Flexibility is key!
The coulterbar can be easily coupled and uncoupled with a coupling hook similar to the front loader coupling. Track markers are attached to the power harrow. Therefore, the power harrow is ready for solo operation within short time. The coulterbar is attached with the Euro-Connection directly to the roller frame and can quickly and easily be hitched thanks to the readily accessible hydraulic and electronic interface.
The e-drill is exclusively designed to be combined with Kverneland power harrows.
