The invention discloses a working method of an adjustable efficient mower. The adjustable efficient mower comprises a mower body, and a cutting mechanism, a driving mechanism, a grass collecting mechanism and a control device are arranged on the mower body; an adjusting device used for adjusting the height of grass pruning is arranged in the cutting mechanism, a compressing device is arranged in the grass collecting mechanism, the input end and the output end of the driving mechanism are connected with the cutting mechanism separately, the grass collecting mechanism is arranged in the rear of the cutting mechanism, and the cutting mechanism, the driving mechanism, the grass collecting mechanism, the adjusting device and the compressing device are connected with the control device. According to the adjustable efficient mower, grass cut off is collected through the grass collecting mechanism, and the collected grass is compressed through the compressing device, so that the space occupied by the collected grass is reduced, the time of grass pouring is shortened, and the working efficiency is improved; meanwhile, through arrangement of the adjusting device, the pruning height can be adjusted based on actual pruning requirements, so that demands of working personnel are better met.
