Spring Loaded Coulter: It is the type of machine in which seed bed is prepared by cast steel material that in front of the coulter, and has spring system that protects the mechanism against strikes. There is opportunity to adjust depth for legs that will meet marks of back wheels of tractor. During planting, if the planting depth is not enough for the machine meeting tractor marks, it can be allow these three each legs on right and left sides to sink into a lower depth level.
Single Disc: It is the type of coulter that prepares seed side by the angle of one disk. Pressure strength will be applied by planting leg can be set by the spring between leg and leg handcuffs.
Double Disc Leg: It is the type of coulter that prepares seed side by the help of distance expanding backwards along with front junction point of two discs. While function of pressure spring is the same at one disc leg, the most important difference of double disc leg is that there are pressure wheels which apply pressure to seed bed. These pressure wheels enable to make planting depth more precisely and can be set by degrees. Ensure that you give the most appropriate position according to the structure of field.
