An electro-mechanical seat swivel system may include a bottom plate mounted on a frame of a machine or vehicle, and top plate pivotally mounted on the bottom plate, and an operator seat mounted on the top plate. A pawl may be movably mounted on the bottom plate and engage latch catch brackets mounted to the top plate to lock the seat in predetermined operator seat positions. An electro-mechanical actuator may be mounted to the seat and operatively coupled to the pawl. Latch control switches disposed at operator controls may be operated to cause the electro-mechanical actuator to disengage from one of the latch catch bracket to allow the seat to be rotated to another of the predetermined operator seat positions where the pawl will engage the corresponding latch catch bracket to again lock the operator seat in place.
