ABSTRACT:
A normally rigid planar framework for mounting a large number of ground working tools is made resilient to accommodate the torsional forces exerted on the rigid structural members of the framework as it passes over uneven ground and the tools are subjected to varying forces as they move through the ground. Resilience of the framework is achieved by having the structural members which are normally rigidly fastened together, fastened together instead by resilient fastening which permits torsional flexing between the rigid members so fastened. Additionally, rigid structural members of the framework which normally are pivotally connected to permit movement only around the pin axis of the pivotal connection, are resiliently pivotally connected so that slight rotation of the structural members can occur around the other two axes which intersect the pin axis of the respective pivotal connections at mutual right angles.
