Alpego - Rotodent RK Power Harrows Wales

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.

Equipment

-1000 rpm gearbox Z=21/33 > 343 g./m
-Drive shafts with shear bolt or automatic cam clutch (to be chosen)
-3-point hitch cat. 2 oscillating
-Movable side plates and adjustable
-Drop-forged tines (RAPIDO version)

Features

TWIN-FORCE K 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 guarantees 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 compaired 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

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.

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.

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

Rotor phasing sequence

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.
