Each tine is preloaded by a pressure spring.
Regardless of the working position, the tines act with a consistent ground contact pressure.
The patented system is hydraulically controlled and can vary the pressure between 500 and 5,000 grammes. This pressure range allows an optimum match to all conditions. If the operating conditions change, the pressure can be adjusted while driving. This ensures that gentle to aggressive weeding can be carried out depending on the development stage of the plants.
