Finger harrow The finger harrow (410 x 7mm) is mounted behind each inter-row element. It is available in different configurations with 3, 4, 5, 7 or 9 tines. Each tine is spring protected by coil. The harrows are placed and bolted on the last tine holder and work inter-row but also on the sowing line. The harrow uproots young weeds and puts the scalped weeds on the surface and supports for a better drying. Roots can not regrowth again. The aggressiveness is adjustable by angle and pressure. Several positions are possible. If necessary it can be lifted completely.
Ridger disc The ridger discs are mounted at the rear of the parallelogram and guided the soil flow to the sowing line. The discs are particularly suitable for developed crops. Aim is to suffocate the weed but not the crop which are growing in the sowing row and are in direct competition of sun, water and nutrients. The crop plants should not get any negative impact.
Adjustable swivel or straight opener discs The adjustable swivel discs (see picture) or straight opener discs are placed on the parallelogram in front of the shares to cut residues and also the soil before the tine to avoid roots disturbance by the tine pass, especially of the young crop. Both versions can be mounted pairwise to the inter-row element. It can be used for early weeding (e.g. quinoa, sugarbeet etc.)
