The invention discloses a novel hydraulic motor reversing system, and particularly relates to the technical field of hydraulic motors. The novel hydraulic motor reversing system comprises a shell, a rear cover is mounted on one side of the shell, a reversing rotating disc is mounted in the middle of the rear cover, a locking device is detachably connected to the outer side of the reversing rotating disc, a reversing device is movably mounted on one side of the reversing rotating disc, and an oil distribution disc is movably mounted on one side of the reversing device. According to the novel hydraulic motor reversing system, the reversing device is mounted on one side of the device, one side of the reversing device is fixed to the reversing rotating disc through the locking device, and meanwhile, the oil distribution disc is mounted on the other side of the reversing device; when the device needs to be subjected to reversing operation, the locking device is taken out, the reversing device is rotated, the oil distribution disc is driven to rotate, and meanwhile, the reversing rotating disc is driven to rotate; and when the reversing rotating disc rotates to a designated position, the locking device is fixed on the surface of a reversing disc, so that the device can be quickly reversed, and the use efficiency of the device is improved.
