The #1 Rigid Shank Assembly has a 100x100mm RHS mounting and a maximum working depth of up to 450mm. It was manufactured in two varieties: one for Agrowplow models manufactured before 1982 and another for models manufactured before 1988 (when the assembly was superseded). To determine the difference, check the shank carrier: pre-1982 models had a simple carrier with no shearpin (meaning the shank could not break back when the maximum breakout threshold was reached). Later pre-1988 models added a shearpin to the shank carrier.
The assembly includes frame mounting, shank, tungsten tile blade, and blade adaptor, as well as all hardware required for assembly.
Some assembly is required.
