rullalevittimet

Rullalevittimet, often translated as roller spreaders or sometimes roller applicators, are agricultural machines designed for distributing granular materials such as fertilizers, seeds, and salt. They function by using a rotating roller or cylinder that picks up the material from a hopper and evenly dispenses it over a designated area. The spread rate is typically controlled by the speed of the roller and the size of openings in the hopper.

These devices can be either towed or mounted onto tractors, and their width of spread varies depending on the model and intended application. Smaller, handheld versions are also available for use in gardens or on smaller plots of land. The primary advantage of rullalevittimet lies in their ability to achieve a uniform distribution, which is crucial for efficient crop fertilization and consistent seeding. This uniformity helps prevent over-application in some areas and under-application in others, leading to better resource utilization and improved yields or coverage. They are generally considered simpler in design and operation compared to some other types of spreaders, such as centrifugal or pneumatic spreaders. Maintenance typically involves cleaning the hopper and roller to prevent material buildup and corrosion.
