Alpego - Erpice Rotante Rotodent DmaX Power Harrow

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 levelling bar is constantly correctly adjusted;
– In the combination with a seed-drill the pressure of the seeding coulters is kept constant

Levelling bar fixed to the roller with independent adjustment
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.
