Power harrows Rotodent DP

The folding power harrow ROTODENT DP, made of high strength steel is available in the working widths 4, 5 and 6 mt. and it is ideal for tractors from 120 to 270 HP.


Features

Rotors designed to avoid soil jamming




Floating lateral frame

In the folding harrows the two folding halves can be made to float, thereby allowing the machine to adjust to the unevenness of the ground.

The power harrows DJ allows oscillation of the side frames only upward.




Stone guards under the gear trough

The front guards prevent rocks from entering to cause rotor damage.




Floating roller mounted on a parallelogramm

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




Levelling bar on roller. Independently adjustable

The leveling bar of the ALPEGO power harrows is directly attached to the rear roller.
This makes it possible to maintain a constant height from the ground, thereby improving the leveling quality and reducing the power absorbed by the power harrow.




Gearbox

By reversing the position of the changeable gears by replacing it, it is possible to have available several rotation ratios of the rotors.
This makes it possible to obtain the best possible performance of the power harrow depending on the type of soil, on the forward speed and on the required degree of crumbling.

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.




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




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




Packer Roller

The PACKER roller has a tubular structure with a large diameter: this makes it very sturdy and particularly suited for the combinations with seed drills.

Several rows of tines guarantee the traction on the ground and a series of adjustable brushes keeps each of them clean.

The result is a compact surface, perfect for sowing.




Crumb roller

The CRUMB roller is suitable for working friable soil, also heavy and wet, and allows a good crumbling and compaction before seeding. Scrapers avoid stopping.




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.
