The A&C Aggregates ripper of the ROCK series has been designed and constructed to meet all user needs on particularly firm terrain and where crop residue is present. The high resistant steel used and the particular structure with bolted joints make the ROCK ripper suitable for heavy-duty working conditions. Each anchor is equipped with a bolted safety device duly sized and a quickrelease tip. It can also be equipped with deflectors to break up the terrain better. The row spacing between the anchors can be easily modified to adapt to the needs of the most demanding operator. The ROCK ripper can also be used in the version without wheels. The rear rollers are equipped with parallelogram hydraulic movement which ensures quick and accurate adjustment of the working depth.
