According to the multi-motor matching control system and method for the pure electric tractor, a high-voltage all-in-one control assembly is electrically connected with a power battery through a high-voltage line loop, and the high-voltage all-in-one control assembly communicates with a walking motor controller, a PTO motor controller and an oil pump motor; the walking motor controller and the PTO motor controller are respectively communicated with the walking motor and the PTO motor through high-voltage lines, the walking motor is in transmission connection with the walking system, the PTO motor is in transmission connection with the PTO system, and the oil pump motor is in transmission connection with the duplex oil pump. The whole machine control module is in communication with the high-voltage all-in-one control assembly, the power battery, the walking motor controller and the PTO motor controller. By means of the multi-motor mechanical decoupling scheme, mechanical transmission parts are reduced, the whole machine efficiency is higher, in addition, the oil pump motor, the walking motor and the PTO motor can be independently closed, and the better energy-saving effect can be achieved.
