Abstract: A center pivot irrigation unit with a plurality of towers supporting an elevated water line has a pair of stabilizers for each tower, one of which extends in a forward direction from the tower and one of which extends in a rearward direction from the tower. Each stabilizer has a distal end that is suspended a short distance above the bottom of the wheels so the stabilizer does not contact the field unless the unit begins to tip.

Abstract: An apparatus includes a swivel having a first flange with a first pivot on one side of a swivel pivot, and a second flange with a second pivot on an opposite side of the swivel pivot, and first, second, third and fourth rods. The first and second rods are each pivotally attached at a respective first end to the first pivot and extend outwardly therefrom. The third and fourth rods are each pivotally attached at a respective first end to the second pivot and extend outwardly therefrom. The first and third rods are respectively pivotable about the first and second pivots in a first plane, and the second and fourth rods are respectively pivotable about the first and second pivots in a second plane, wherein the first plane is parallel to the second plane.

Abstract: A germicidal mailbox receives mail in an internal, rotatable cage, and tumbles such mail while irradiating it with ultraviolet light at a wavelength of 254 nanometers to kill or render inert microbes on the mail that could carry diseases to which humans are susceptible. After the mail has been tumbled and irradiated, it is safe for handling by humans without the danger of infection and disease from microbes that may purposefully, through terrorism, or accidentally have become attached to the mail.
