Erpice Rotante Rotodent DmaX

The ROTODENT DmaX is a folding power harrow unique in its category. Its strong point is the TWIN-FORCE “maX” mechanical peculiarity and its heavy-duty structure. It is available in the working widths 4.5 and 5, 6, 7 and 8 m. for tractors from 180 to 500 HP.

Features

TWIN-FORCE MAX transmission

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 compared 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
Hitching to tractors of very great power

AI Guard

The AI-GUARD, from the AI package, foresees the monitoring of several parameters of the machine. From the monitor it is possible to check the temperature of the mechanical transmission organs and their number of revolutions. Visual/acoustic alarms send a warning when the critical levels have been exceeded. Moreover, the system recommends the programmed maintenance operations.

It will also be compatible with the new electronic systems which Alpego will develop in the future

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

Barra niveladora de paralelogramo

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

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.

Set of forged quick replaceable tines

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.

Spacing between rotors 25 cm for a better crumbling of the soil and a reduced power absorption

Rotor phasing sequence

Lateral universal joints with automatic cam clutch

The universal joints with Walterscheid automatic cam clutch guarantee the maximum working reliability even under the worst conditions.

The DmaX 700 and 800 are equipped with the P700 central universal joint and with the lateral P600 lateral universal joints

Sturdy wider single-beam frame which permits the assembly of an hydraulic hitch for seed-drills

Combination with a seed drill

The power harrow can easily be combined with an Alpego pneumatic seed-drill.

High tensile steel frame

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.
