Abstract: I provide the quick release cutting hub assembly for a pelletizer with a cutting plane formed between a cutter and a die plate comprising a pelletizer shaft having a bore, a cutter assembly supporting the cutter and a support means mounted on one end of the pelletizer shaft and supporting the cutter assembly and having a spring means in compression urging the cutter assembly toward the cutting plane and also having a quick release means mounted within the support means for releasing the cutter assembly from the shaft. The quick release means when actuated bears against the cutter assembly and is held in place due to the pressure exerted by the compression of the spring located in the support means.
