Power harrows Rotodent RK
The professional rigid power harrow ROTODENT RK, 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 3, 3.5 and 4 m. It is ideal for tractors from 90 to 200 HP.
Features
Rotors mounted on tapered roller bearings TWIN-FORCE
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
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.
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.

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.
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.
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.
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.
