Swing arm corner

Swing Arm Corners

The Swing Arm Corner System (SAC) lets you get more irrigated acres without buying more land or setting up a new water system. Our exclusive swing span design provides uniform application of water and chemicals and can be retrofitted on existing Reinke systems or on many competitor systems.

The SAC allows operators to change the orientation to either a “leading” or “following” position to increase the number of irrigated acres in part circle applications. Reinke offers the following Swing Arm Corner sizes:

  • Mini-SAC: Featuring a 156' span and 51' end boom. Provides 207' of coverage (approximatley 297' with end gun)
  • Mini-SAC: Featuring a 175' span and 61' end boom. Provides 236' of coverage (approximately 326' with end gun)
  • Standard  SAC: Featuring a 194' span and 86' end boom. Provides 280' of coverage (approximately 370' with end gun)
  • Super SAC: Featuring a 213' span and 105' end boom. Provides 318' of coverage (approximately 408' with end gun)

SAC size options


  • Navigator GPS – with Real Time Kinematic (RTK) surveyor-grade equipment, the Navigator series of GPS controls provides extreme accuracy in timing and application
  • Accu-Corner – Assures even, accurate application throughout the corner. Minimizes over/under watering: Programmable logic controller, 12 groups of sprinklers and up to 61 programmable stages, Unique operator interface. NOTE: The Accu-Corner is not available with the Mini-SAC offerings.
  • Exclusive Patented Energy Saver Package (ESP) – Utilizes an extra sprinkler package with automatic valves to supply additional water, instead of needless pressure during the retraction cycle of the swing arm corner. Save hundreds of dollars every season with each system revolution. See chart.
