An electric circuit for remotely starting and controlling the direction of a center pivot irrigation system comprises a first transformer, a second transformer, a first relay, a second relay, a third relay, and a fourth relay. The first transformer is coupled to a voltage source with a first voltage and may step the first voltage down to a second voltage. The second transformer is coupled to the first transformer, receiving a third voltage and stepping the third voltage up to a fourth voltage. The first relay may include contacts that are open when the irrigation system is started remotely. The second relay may include contacts that are closed when the irrigation system is started remotely. The third relay may include contacts that are closed momentarily to drive the system in a first direction. The fourth relay may include contacts that are closed momentarily to drive the system in a second direction.
