Foldable power harrow DKTOP

The new DK TOP is a professional folding power harrow thanks to its TWIN-FORCE tine support with tapered roller bearings is particularly suited in combination with seed drills and it is available in the working widths 4 - 4.5 – 5 - 6 mt. It is ideal for tractors from 130 to 350 HP

Features

The Twin-Force system consists of 2 rotors held together by a single support plate for a double sturdiness. The quality of the Timken  taper roller bearings combined with the hardened gears guarantee the highest reliability of the transmission.

 The power harrow with all these devices makes it possible to reach excellent performances in terms of:

  • A greater working depth (on average more than 100 mm. as compaired with a normal power harrow)

  • An increase of the forward speed

  • The best use of the available power

  • The greatest reliability and a minimum of maintenance

The quick system can be supplied separately as a set as an alternative to the traditional system, or it can be mounted directly on the machine. img_rapidoforgiato

 

The 2 folding sections can follow the unevenness of the soil thanks to a floating system (excursion of 10° upwards or downwards) or be rigid.

In order to make our power harrows compatible with high-power tractors, we have developed 3-point hitches of 4th. cat.

The new DK-TOP features new shaped lateral plates with wearproof skids. The new design fosters the best flow of the soil toward the rear rollers.

In order to prevent stones from penetrating between the rotors, we have developed even more efficient stone guards.

Thanks to the PARALLELOGRAM system of depth adjustment , the rear roller constantly maintains the same degree of inclination, therefore:

  • The leveling bar is constantly correctly adjusted;
  • In the combination with a seed-drill the pressure of the seeding coulters is kept constant.

The levelling bar is mounted directly on the rear roller, thereby improving the levelling quality and decreasing the power absorption.

 

The gearbox is designed and built in-house according to Alpego specifications.

By reversing or replacing the pair of gears, you can change the rotor rotation ratios without risking damage to the gearbox.
This optimises the work of the power harrow according to the type of soil, working speed and required degree of crumbling.

The bevel gear with helical teeth also ensures the full efficiency and strength of the system.

All the supports of the tines mounted on the power harrows we manufacture follow a very precise sequence. This prevents vibrations of the transmission organs with the resulting decrease of the absorbed power.

The power harrow can easily be combined with an AS-Pro or ASmaX front hopper.

rullo GABBIA

Cage Roller

The CAGE roller is suitable for dry soils of medium density.
With the extra kits (available only for the G5 series) it is possible to add some pipes to the cage, thereby increasing the supporting surface.
The structure of the cage does not make it suitable to support very heavy loads, such as the combined implements.

rullo SPIRALE

Spiral Roller

The SPIRAL roller creates a soft and uniform seeding surface and is suitable for medium and light soils. It can’t be used in the combinations with the seed drill

rullo SPUNTONI

Spike Roller

The SPIKE roller is very versatile, it works well even when the soil is damp and compacted. It can be used in the combinations with the seed drill.

rullo PACKER

Rullo Packer

Il rullo PACKER ha una struttura tubulare di grande diametro, questo lo rende molto robusto e particolarmente adatto alle combinazioni con seminatrice.
Diverse file di denti garantiscono la trazione col suolo e una serie di spatole registrabili singolarmente li mantiene puliti.
Il risultato è una superficie compatta, perfetta per la semina.

Rubber Roller

The GOMMA (rubber) roller is suited for combinations with seed drills for cereals: it guarantees that the seed is placed at a constant depth.
The rubber covered surface and its large diameter decrease the clamming effect of the soil and makes it a roller suited for any work condition.

rullo TRAPEZIO

Trapeze Roller

The notched cast-iron roller ridges are spaced 12.5 cm or 15 cm depending on row spacing.With its diameter of 505 mm it combines a perfect rotation and a pressing of the seeding line.Designed for the combination can also work alone.It adapts perfectly to all types of dry or wet soil even in the presence of stones or crop residues.
