The Kverneland S series is a heavy-duty power harrow for tractors up to 250hp. With the Kverneland heavy-duty, self-supporting trough design and the Quick-Fit tines, the S series is the right solution for larger farms and contractors.
The standard gearbox with a rotor speed of 298rpm is equipped with replaceable gears. In order to cope with various soil conditions, the control of rotor speed is crucial. Therefore, additional gear sets to achieve 365rpm or 435 rpm are available as an option. Parallelogram-guided side deflectors with overload protection allow smooth operation and an even soil surface without any ridges.
The S series is equipped with Quick-Fit tines as standard. By a special pin and clip system, exchanging the tines has become very easy and quick without the need for tools. Depending on soil conditions, forward active tines are available which are more aggressive. In order to cope with difficult soil conditions, the trough design provides a large clearance between the tine holders and the trough bottom. This reduces the risk of blockage and ensures optimum performance also in case of large amounts of residues and stones.

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.
|Model||Trough dimension (mm)||Gears||Ø Shaft (mm)||Bearings (mm)||Bearing distance (mm)||Rotor clearance (mm)|
|M series||140 x 400||tempered||40 & 45||80 - 90||70||98.25|
|H series||165 x 400||tempered & hardened||45 & 50||90 - 100||84.5||90.5|
|S series||200 x 400||hardened||55 & 60||110 - 120||110.5||100|
The S Series is equipped with Quick-Fit tines as standard. These are secured by a special pin and clip mounted in the tine holder. Tine replacement is, therefore, very easy without the need for tools. Downtime can be further minimized by an optional carbide layering of the tines. This will ensure a long liftime and minimum wearing even in tough and abrasive soils.
Depending on soil conditions there is the choice of Standard and Active tines.
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.
Re-consolidation for a stable soil structure
Rollers ensure re-compaction 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
Actiline Roller ø550mm – 185 kg/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.
