Combined soil working machine - has tool carrying bridge supported on rear wheels by struts inclinable to raise or lower bridge

摘要

Tools are suspended from a support frame (T) carried by a bridge (B) to which the rear wheel (R) are connected by struts (17). The inclination of the struts is variable by a hydraulic ram (18) to adjust the height of the bridge (B) above the ground. The bridge (B) is pivotable relative to the tractor about transverse, longitudinal and vertical axes. The bridge (B) is pivotable relative to the rear wheels (R) about transverse and vertical axes. The support frame (T) is rigidly connected to the bridge (B) by members (20, 22).
