Alpego - Rotodent DP Power Harrow

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.

Equipment
 

- 1000 rpm gearbox - rotor shaft rotation at: Z=30/24 (328 rpm)
- 3-gearbox transmission with speed selection
- Central drive shaft 1"3/8 Z=6
- Lateral drive shafts with shear bolt or automatic cam clutch (to be chosen)
- Hydraulic unlocking system
- Rear light boards
- 3-point hitch cat. 2 and 3 oscillating
- Movable side plates
- Central track eraser

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.

Half-guards for the rotors (option)
- Two half-moons made of wear-resistant material
- High protection against wear and external agents (stones, strings, pieces of metal…)
- Self-cleaning because they turn with the rotor
- Easy removal of the tines because they are attached to them

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.

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

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