It is used to stop the growth of green manures sown on plots at rest.
The action of this roller is to stop the sap flow of plants and leave a mulch on the ground. The cutting blades break the stems in several spots and the weight of the roller coats the vegetation. After a few days, the plants die, and the cover turns yellow. This manual roller is an adaptation of rollers generally adapting on tractors.
It consists of a closed steel cylinder, with a cap on the side that allows it to be filled with water to increase its weight, and empty it for easy transport or storage.
