ABSTRACT Seed drill has a row of coulters which are raised and lowered by a beam extending along and above the row of coulters and connected to the coulters by spring assemblies. The beam is raised and lowered relative to the frame of the drill by two rams to actuate the coulters. The mounting of the beam comprises an articulated joint, such as a ball joint, which permits the ends of the beam to rise and fall independently of each other relative to the frame thereby permitting improved contour following by the coulters and avoiding excessive loads on the beam in the event of failure of one of the rams.
