Abstract

The agricultural seed drill comprises a first frame (10) for connection to a towing vehicle, a second frame (14) and a pivotal connection between the two frames. Arm assemblies (18) are independently pivotally mounted on the second frame and each arm assembly carries at least one disc (22) and at least one roller (24). Front springs (26) and rear springs (28) acting between the arm assemblies and the second frame are disposed respectively forward of the transverse axis of the roller and rearward of the transverse axis. The springs are arranged such that the depth fo operation of discs is independent of the weight of material in a container which is supported on the second frame.
