Kverneland serie H / Erpici Rotanti / Erpici Rotanti / Lavorazione terreno / Kverneland brand Italy / Home

Gli erpici rotanti della serie H rappresentano la gamma media utilizzabile nella maggior parte delle situazioni. Grazie alla cassa auto-portante formata da una doppia flangia sagomata è stato possibile aumentare la resistenza senza intaccare il peso e il design della macchina. Caratteristiche importanti come la distanza tra rotori di 25 cm, i doppi cuscinetti conici, la testata rinforzata e il porta denti modulare sono alla base di questa serie.

Due flange da 6 mm assicurano il mantenimento perfetto della distanza tra le casse dei rotori ad alta rigidità con dimensione di 140 x 400 mm.

L’albero di trasmissione da 50 mm è supportato da due ampi cuscinetti conici, rispettivamente da 45 e 50 mm di diametro; gli ingranaggi hanno una distanza di 55 e 40 mm e permettono un disimpegno tra la base della cassa e il porta denti di 95 cm. Il flusso di terreno e i residui passano agilmente senza bloccaggi.

I Vantaggi:

Trasmissione orizzontale e telaio auto-portante conferiscono robustezza, leggerezza e grande affidabilità
Baricentro ravvicinato e richiesta per il sollevamento ridotta
4 rotori/m – caratteristica unica
Massima versatilità – semplice e rapida combinazione con qualsiasi seminatrice (integrata o via attacco a triangolo)
Prestazioni ottimali e bassa richiesta di potenza grazie ai denti ravvicinati (distanza di 25 cm) e la disposizione elicoidale
Nuovo rullo Packer più leggero (-60 kg su 3 m) con cuscinetti senza manutenzione

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

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.

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.

Quick-fit and carbide tines

The quick-fit tines for easy replacement and carbide tines for a longer lifetime and minimum wearing are available as an option.

Kverneland Quick-fit tines are simply fixed to the tine holder by a pin and a clip. All tines can be quickly replaced without any tools
Down time can be minimised by optional carbide layered Quick-Fit tines. These tines ensure a long lifetime and minimum wearing even in tough and abrasive soils.

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.
