The invention discloses a track tensioning adjusting mechanism, a track harvester and a track tensioning adjusting method in the technical field of track tensioning. The track tensioning adjusting mechanism comprises a hydraulic oil cylinder, a walking edge beam, an energy accumulator, a hydraulic valve and a hydraulic lock. An oil cylinder support lug is integrated at one end of the hydraulic oil cylinder, the oil cylinder support lug is connected with the rectangular tube of the transmission frame through a pin shaft, and the other end of the hydraulic oil cylinder is connected with the walking edge beam through a pin shaft; the walking edge beam comprises a limiting groove, and the limiting groove is connected with the rectangular pipe in a sliding mode. The energy accumulator is connected with the hydraulic oil cylinder and is used for changing the reserve volume of hydraulic oil in the hydraulic oil cylinder according to the pressure change; the hydraulic valve is connected with the hydraulic oil cylinder and is used for controlling the hydraulic oil cylinder to stretch out and draw back to move as a floating oil cylinder; the hydraulic lock is connected with the large cavity end of the hydraulic oil cylinder; the technical problem that in the prior art, a crawler belt tensioning mechanism and a harvester are damaged due to overlarge instant impact can be solved.
