A remotely operated cutting mode shifting apparatus for use with a decoking tool of the type in which the cutting mode is changed by rotation of a diverter valve plate, has a shifter body adapted for mounting to the decoking tool and a control rod for engaging with the diverter valve plate. It includes a mechanism within the shifter body for rotating the control rod to drive the diverter valve plate to shift the cutting mode of the decoking tool upon release of cutting fluid pressure from the tool.
