The invention relates to a hydraulic manifold apparatus and system, connectable to a dual stage motor, for use in the topdrive of drilling operations. The hydraulic manifold is switchable between a low speed, high torque configuration and a high speed, low torque configuration. Valves within the manifold control the flow of working fluid through the manifold and into and out of the motor. Switching means are further provided to control the opening and closing of the valves. In the low speed, high torque configuration, working fluid enters each stage of the dual motor simultaneously, in parallel. In the high speed, low torque configuration, working fluid enters a first stage of the motor, returns to the hydraulic manifold, then enters a second stage of the motor, before returning again to the hydraulic manifold. Thus during high speed, low torque operation, working fluid enters each stage of the dual motor in series.
