1. A system for automatically rotating a steering wheel of an agricultural machine, the system comprising an auto-steering device,
wherein the auto-steering device includes:
a rotation assembly surrounding a circumference of a pillar of the steering wheel and coupled to the pillar, wherein the rotation assembly has an opening through which the pillar of the steering wheel is inserted, and wherein a first gear is disposed on a circumference of an outer surface of the rotation assembly;
a frame assembly including a central opening surrounding the rotation assembly, wherein the pillar of the steering wheel is inserted into the central opening, wherein a second gear, which engages with the first gear, is disposed on an inner surface of the central opening;
wherein the rotation assembly, the frame assembly, the first gear and the second gear are concentrically arranged around the pillar;
a motor configured to rotate the second gear to rotate the rotation assembly and the steering wheel through the first gear; and
a reducer disposed between the second gear and the motor and configured to decrease a number of rotations of the motor to transmit a driving force having a decreased number of rotations to the second gear.
