To provide a DPF control device capable of regenerating DPF while continuing work when there is little obstacle in the work.

The DPF control device 2 includes a filter 31 collecting particulate matter in exhaust gas from an engine 41 and a regeneration means 32 removing deposited particulate matter to regenerate the filter 31. The DPF control device 2 includes: deposition amount of detection means 33a, 33b detecting a deposition amount of the particulate matter deposited on the filter 31; a work machine driven by hydraulic oil supplied from a hydraulic pump 47 rotated by the engine 41; and a control means 20 classifying the deposition amount into a plurality of deposition levels La, classifying the state of the work machine into a plurality of work state levels Lw, and setting the work state level Lw corresponding to the detected deposition level La as a condition for allowing the regeneration of the filter 31.
