The professional rigid power harrow ROTODENT RM, thanks to its TWIN-FORCE tine support with tapered roller bearings is available in the working widths 3, 3.5 SUPER and 4m SUPER and it is ideal for tractors from 80 to 170 HP.
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:
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.
The front guards prevent rocks from entering to cause rotor damage.
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 manufactured according to internal Alpego specifications.
The reversal or the replacement of the pair of gears makes it possible to change the number of revolutions of the rotors and this makes it possible to greatly improve the performance of the power harrow, depending on the forward speed and on the required degree of soil crumbling.
The power harrow can easily be combined with an Alpego pneumatic seed-drill.

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.
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
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
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.
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.
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.
