Abstract
A method and means for converting a water drive center pivot irrigation system to air drive is described whereby the more economical air drive is substituted for the water drive on each of the drive towers. The water drive cylinder on each of the drive towers of the system is modified to function as an air cylinder which is operatively connected to the trojan bar on the drive tower whereby actuation of the air cylinder will cause the trojan bar to be reciprocally moved to drive at least one of the drive wheels on the tower. An alignment panel is mounted on the drive tower and is connected to the air cylinder for controlling the operation of the same. The alignment panel is operatively secured to the existing alignment control apparatus on the drive tower so that the alignment panel will function in response to the alignment control apparatus. An air compressor is preferably placed at the well site and is connected to each of the alignment panels and to the drive cylinder on the lead tower for supplying air thereto under pressure.
