Single disc sowing legs should be used where there is a lot of stubble in the field. It is less affected by the form of tillage and moisture condition. It can’t sow deep with disc leg type. Usage area in sowing small seeds is limited. However, it is more difficult to obtain equal sowing depths with these legs when compared to the spring chisel and axe leg. The reason for this is as follows; when discs encounter an obstacle and jump over it, the spring axe legs push the obstacle sideways. Therefore, it may be appropriate to use single disc feet on lumpy, heavy and rocky soils. However, sowing depth will not be equal.
