Power Harrows

Power harrows are the most flexible professional soil tillage machines, performing in all soil types and situations. n addition, combined with a broadcast seed-drill, they provide a high level of performance in both economic and agronomic terms.

Alpego Mechanics

Unique and performing

The ball-bearing mechanics is mounted on a wide range of power harrows, up to 6 meter wide and it offers excellent structural performances. The machines equipped with this kind of solution are ideal for the preparation of the seedbed. 

The patented Twin Force K, used in the professional models is ideal for deep and combined tillage. The machines equipped with this type of mechanics are suited to be used with high-power tractors.

The patented Twin-Force MAX solution, used in the top-of-the-range professional models further improves the structural features and yields the utmost reliability in the use of very high power tractors of up to 500 HP.

Rotor timing sequence

All the tines’ holders mounted on the power harrows we manufacture follow a very precise sequence. This prevents vibrations of the transmission gears with the resulting decrease of power absorption.

Types of shanks

The right tine for every need. The experience of many years in the field has led Alpego to develop a wide range of shanks suited for the most varied uses. The special shape and angle of inclination guarantee an excellent crumbling with a decreased amount of power absorption.

TRANSMISSIONS AND MECHANICS

Entirely designed at Alpego

SPEED GEAR CHANGE

By switching or replacing the gear pair it is possible to obtain several different rpm of the rotors. This makes it possible to optimize the work of the power harrow depending on the type of soil, on the forward speed and on the degree of required crumbling.

SELF-LUBRICATION

Because the outer casings of the large-dimension bevel gears are enveloping them, these are able to perform a very important self-lubrication, while cooling all internal components at the same time. Thanks to this solution the Alpego power harrows do not need any further cooling systems.

ALPEGO LUBRICANTS

Alpego has always invested in research and development of lubricants with specific characteristics for the use in own machines. Thanks to these features, power harrows benefit from a longer life and optimal functioning of mechanical components.

ALPEGO POWER HARROWS: ALL THE ADVANTAGES

Details that make the difference

Range of rigid power harrows

Three types of mechanics for a full range up to 4 metres

Range of folding power harrows

Three types of mechanics for a full range up to 8 metres

Leggero e resistente

Gli erpici a sfera prodotti da Alpego garantiscono elevate prestazioni su modelli dai pesi contenuti, con una tenuta di potenza fino ai 270HP.

Le caratteristiche di questa meccanica sono:

  • albero con trattamento superficiale
  • doppio cuscinetto a sfera in linea
  • cuscinetto superiore in asse con la vasca
  • ingrassatore superiore per garantire la lubrificazione
  • supporto del rotore avvitato
  • protezione contro i corpi estranei di serie
  • semiprotezioni dei rotori montate sul piattello
  • labirinto antipolvere

 

La struttura totalmente avvitata, ripresa dalle meccaniche superiori, facilita eventuali manutenzioni nel tempo.

Veloce e potente

Il sistema brevettato Twin-Force K consiste in 2 rotori tenuti assieme da un unico supporto per una robustezza raddoppiata. Utilizza cuscinetti conici Timken autolubrificati che, abbinati all’utilizzo di ingranaggi cementati, garantiscono il massimo dell’affidabilità della trasmissione.

L’erpice così equipaggiato permette quindi il raggiungimento di performance eccezionali in termini di:

  • Maggiore profondità di lavoro
  • Incremento della velocità di avanzamento
  • Utilizzo ottimale della potenza disponibile
  • Massima affidabilità e manutenzioni minimizzate

Incredibilmente efficiente

Le macchine top di gamma sono dotate della meccanica brevettata Twin-Force MAX.

Questa soluzione esalta le caratteristiche del “K” grazie ad una maggior lubrificazione, una struttura più robusta e maggior luce libera.

L’erpice così equipaggiato permette il raggiungimento di performance eccellenti in termini di:

  • Incremento della  profondità di lavoro
  • Maggior capacità di lavoro
  • Utilizzo ottimale in condizioni altamente estreme
  • Massima affidabilità
  • Manutenzioni minimizzate
  • Progettato e realizzato per sfruttare i trattori di   altissima potenza

Light weight and durable

The ball-bearing power harrows manufactured by Alpego guarantee high performance on light-weight models with a power output of up to 270HP.

The characteristics of these mechanics are:

  • • shaft with surface treatment
  • • dual inline ball bearing
  • • upper bearing in axis with upper grease pan
  • • to ensure lubrication
  • • screwed rotor support
  • • guard against foreign bodies as standard
  • • rotor half-rock guards mounted on the
  • maze-shaped dust protection

The entire structure is screwed on from the top, which makes future maintenance procedures easier.

Fast and powerful

The patented Twin-Force K system consists of 2 rotors held together by a single support for double strength. It presents Timken self-lubricating tapered roller bearings which, combined with hardened gears, guarantee the utmost reliability of the transmission.

The power harrow thus equipped makes it possible to achieve exceptional performance in terms of:

  • Greater working depth
  • Increased forward speed
  • Optimal utilisation of available power
  • Maximum reliability and minimised maintenance

Incredibly efficient

The top-of-the range machines are equipped with the patented Twin-Force MAX mechanics.

This solution enhances the features of the “K”, thanks to better lubrication, a sturdier structure and an increased ground clearance.

The power harrow thus equipped makes it possible to achieve exceptional performance in terms of:

  • Increased working depth
  • Increased work capacity
  • Optimal use in highly extreme conditions
  • Maximum reliability
  • Minimised maintenance
  • Designed and built to take advantage of ultra-high-power tractors
