Abstract A height adjusting mechanism for a framework that supports a multiplicity of ground working tools of an agricultural implement operating at variable depths of ground penetration is disclosed. The variability is achieved by rotation of framework supporting rock shafts pivoting around pivot points on wheel supported wheel frames, which in turn support the rock shafts; rotation causes the lateral spacing of the wheels to vary also. Additionally, flexibility of the framework optionally is provided by having certain fastenings and pivotal attachments between framework members in the form of resilient connections. The novel flexible framework is not critical to operation of the height adjusting mechanism, the latter being operable also with rigid framework.
