In the field the weight of the seed drill acts directly on the rear roller. The power harrow retains its freedom of movement and can ride over stones.
Mounted on power harrows or compact combinations, the weight of the seed drill acts right at the front end. The additional weight of the seed drill on the rear roller provides even better consolidation for the seedbed. The gap between the coulters and the power harrow rear roller is minimised to form a compact unit.
Suffolk coulters or single-disc coulters
Coulter pressure up to 25 kg.
Depth guidance wheels optional.
VITASEM A CLASSIC models have a smaller seed hopper. They are consequently lighter and designed for operation with smaller 4-cylinder tractors. Very good visibility to the rear is possible thanks to the lower seed hopper.
The large DUAL DISC coulters allow high working speeds when mulch drilling and operating in heavy, hard soils.
Coulter disc diameter 350 mm.
Coulter pressure up to 50 kg.
VITASEM A drills are quickly and easily fitted to the harrow.
Easy to fit:
Drive under the seed drill and lift the power harrow.
Fit retention bars to secure seed drill.
Remove retention pins on rear roller to create parallel linkage between packer and drill
Fit top link to seed drill.
The implement-mounted drill is fixed to the rear roller and guided via the top link that forms a parallel linkage.
Packer and seed drill form a single unit.
This enables the working depth of the power harrow to be changed by adjusting the roller without having to correct the seed drill top link.
A hydraulic cylinder is also available to pivot the seed drill up over the power harrow.
Best position of centre of gravity in relation to tractor.
The high ground clearance of the drill coulters means that the power harrow can be used on its own - for levelling of plough furrows, for example.
