It is possible to equip your spreading implement with an exact/gooseneck/swinging scatterer in order to fertilise areas where the use of your spreading implement is impossible (e.g. due to the soil moisture or working width). In this case, a system of manual or hydraulic valves directs the flow of slurry to the scatterer.
All arable and meadow injectors controlled by a sequential block have a system (standard or optional depending on the model) to lift the injector in wet areas, thus preventing it from sinking too deeply. This device consists of a valve that lifts the rear implement when going from a dry area to a wet one, while keeping the feeding valve open and the macerator active.
