The invention discloses a control method and system of a hydraulic clutch, a controller and mechanical equipment, and relates to the technical field of hydraulics, the method comprises the following steps: when the pressure in a main clutch oil cylinder in a hydraulic system corresponding to a to-be-controlled hydraulic clutch reaches a preset pressure value, keeping the current current of a proportional pressure reducing valve in the hydraulic system unchanged; keeping the pressure in a brake oil cylinder in the hydraulic system for a preset time length so as to completely relieve the pressure in the brake oil cylinder in the hydraulic system; and after the pressure in the brake oil cylinder is completely relieved, the current of the proportional pressure reducing valve is increased so as to increase the pressure in the main clutch oil cylinder until the main clutch of the hydraulic clutch to be controlled rotates. According to the hydraulic clutch, before the main clutch rotates, it can be effectively guara
