Folding rollers are used on large plots. Their major task is compressing the soil. They are used for breaking up the turfs which cannot be broken up by cultivation tools and leveling the surface of farmlands. The rollers can be used in the farmland before and after planting. If, they are used in the farmland be- fore planting, they break up and crush clods in it, compacts the soil and ensures a balance between the air pockets, regulates water - air rates and prepares better seed beds.

If, they are used after planting, they help increasing the relation of seeds with the soil, drawing the water at lower levels of the soil up to the region where the seeds are planted and thereby germination.
