Kverneland serie S

Per potenze fino a 250 CV

La serie S di Kverneland si compone di erpici rotanti per uso intenso con trattori di potenza fino a 250 CV. È la soluzione ideale per grosse aziende e contoterzisti grazie al design della cassa rinforzata auto-portante e i denti a sostituzione rapida Quick-fit.

La trasmissione principale è fornita con ingranaggi intercambiabili per poter adattare meglio la macchina alle condizioni di lavoro. La versione standard garantisce una velocità di 298 RPM; a richiesta, sono disponibili velocità di rotazione di 365 e 435 RPM. I deflettori laterali a parallelogramma e sistema di sicurezza a molla garantiscono un livellamento perfetto senza creste.

I denti Quick-fit sono di serie. Attraverso un perno bloccato con una chiavetta, il cambio dei denti è semplice e rapido senza il bisogno di utilizzare strumenti particolari. Se le condizioni del terreno richiedono maggior aggressività di penetrazione, i denti Active forniscono un’azione più intensa e attiva. Il disimpegno tra il supporto dei denti e la base della cassa è ampio e permette il passaggio di un gran flusso di terreno e residui, nonché sassi se si opera in terreni pietrosi.

Vantaggi:

  • Telaio auto-portante altamente resistente ad abrasione e torsione
  • Testata d’attacco rinforzata
  • 4 rotori/m
  • Massima versatilità – possibilità di combinazione con tutte le seminatrici
  • Riduzione dei picchi di carico e del consumo di carburante
  • Ampia scelta di rulli

Heavy-duty trough design

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.

Range of tines - S series

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. 

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.

Kverneland Packer Rollers

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

  • For medium to heavy soils, also in wet, stony and sticky conditions due to the independent skids and knives
  • The cutting discs break the larger clods whilst the adjustable knives cut the remaining clods resulting in optimal clod breakdown and fine seedbed preparation

Cracker Packer ø550mm – 200kg/m

  • For medium to heavy soils
  • Real stripe-wise reconsolidation (12.5cm) in front of seed coulters – only 50% of the soil surface is rolled
  • Good absorption of water
  • Sufficient soil left loose for covering of seeds
  • Good crumbling effect especially on heavy soils
  • Smooth rings and passive-angled knives – no blocking when used in mulch conditions

 Tooth Packer roller ø575mm – 160kg/m

  • Medium to heavy soils
  • Good carrying capacity
  • Good self-cleaning effect
  • Central adjustable scraper bar with independently adjustable scrapers
  • Carbide coated scrapers on request
  • Most versatile roller – especially as part of heavy power harrow/seed drill combination

 Cage roller ø550mm – 90kg/m

  • Light to medium soil and dry working conditions e.g. seed bed preparation for potato planting
  • 10 bars for a good loading capacity and option in wet conditions

Euro-Connection

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.
