The present application relates to the technical field of construction machinery, in particular to an excavator lower part length regulating system and an excavator. The excavator lower part length regulating system includes: a lower part walking beam; a caterpillar track, provided around the lower part walking beam; and a regulating assembly, adapted to regulating the length of the lower part walking beam and the height of the caterpillar track along a longitudinal direction. The regulating assembly has an extension state in which the lower part walking beam is driven to be elongated and the caterpillar track is driven to descend along a longitudinal direction, and a contraction state in which the lower part walking beam is driven to be shortened and the caterpillar track is driven to ascend along the longitudinal direction. The present application provides the excavator lower part length regulating system, which regulates the length of the lower part walking beam and concomitantly regulates the height of the caterpillar track along the longitudinal direction by providing the regulating assembly, to realize an adaptive regulation of the caterpillar track with a constant perimeter, overcome the defect that the traditional excavator fails to regulate the ground pressure; and provide the excavator capable of regulating the ground pressure according to requirements.
