Since the beginning of the Macadamia industry in the Northern Rivers, McKEECO General Engineering have been building and servicing the MKI nut cracker. Since then we have seen them installed in major processors in Australia & Overseas.
Late 2016 saw a major re-design and the birth of the MKII cracker, a smaller, simpler machine with the same capacity as the MKI.
All components are manufactured on state of the art CNC machines with the latest in tooling.
