Kverneland cuts weight on its drills

The layout on Kverneland’s latest U-drill may be similar to existing models, with packer tyres leading two rows of discs, then a staggered row of packer/transport tyres and a new double-disc coulter assembly.


What’s different is that the 6m model weighs 3t less than its predecessor.


“The lower weight and larger packer tyres make the U-drill (pictured above) easier to pull,” says product manager Thorsten Kreft. “It can run behind a less powerful tractor.”


As well as a continuous flow for the fan, the U-drill needs only one single-acting hydraulic service and just 3.5 litres of oil. In-cab selection and transducers on the depth adjustment cylinders enable the U-drill operator to alter depth on the move and lift out the front tyres.


The discs are shared with the new Qualidisc compact cultivator. Each is mounted on its own rubber suspension arm and has sealed bearings. They are more aggressive than those on the MSC.


Next, 900mm packer tyres with 250mm stagger to discourage sticky soil build-up crush any remaining clods and reconsolidate the soil to encourage water into the seeding zone through capillary action.


They are aligned with the new “CD” coulter assembly, comprising a narrow double-disc opener and following press wheel.


“The 380mm diameter coulters have up to 100kg of pressure – compared with 160kg on the MSC drill – and can drop into hollows as well as rise over crests for more accurate seeding depth,” Mr Kreft points out.


A backbone chassis is another change and, with the centre-split wings folded, it is easy to reach the two Accord seed metering assemblies that allow half drill shut-off.


A 4,350-litre slimline hopper is mounted to the chassis on weigh cells, mainly to provide more accurate seed rate control than a theoretical calibration.

A compact strip-till cultivator from Kverneland, called the Kultistrip (pictured), will be available in plain and slurry injector forms, with 45cm strip spacing suiting oilseed rape, sugar beet and maize.


Rubber wheels either side of the front disc provide depth control and hold rape stalks (and other material) while it is cut. They are then cleared to one side by spring-loaded finger discs.


Next, a winged soil-loosening tine adjustable to 30cm working depth creates fissures through any compaction. It has a built-in outlet for placing granular fertiliser from a front-mounted hopper.


Large discs either side of the tine prevent soil being thrown from the cultivated strip, which is consolidated by a choice of finishing tools – crumbler, V-press roller or Flexroller for lighter soils.


All elements are maintenance-free and the only tool needed adjusts the side discs from straight to angled.

Kverneland is working hard to cut both weight and maintenance requirements. The Qualidisc Farmer compact cultivator (pictured), it points out, is 15% lighter than the regular version to make it suitable for smaller tractors. Likewise, the NG-H 101 folding power harrow is lighter too.


In the case of the Qualidisc, the weight has come off the frame. All the key features remain, including two rows of maintenance-free discs. Equally, no tools are needed to make adjustments on the 3-4m rigid and 4-6m folding implements.


The 6m version of the NG-H 101 F30 with 500mm packer weighs 3,450kg and needs upwards of 130hp to pull it.
