摘要：
A digging assembly for a plough. The digging assembly has a digging blade assembly that is moved through the soil to form a slot, and a closing tool assembly that forms a seed bed by partly closing the slot formed by the digging blade assembly. Following the closing tool assembly is a seed boot that delivers seed to the seed bed formed by the closing tool assembly.
