Lindsay Corporation has introduced a new, advanced GPS Guidance option for the Zimmatic 9500L – a cost-effective solution that gives growers precise and maintenance-free lateral tracking.

“This exciting new product gives growers the ability to navigate their Zimmatic lateral systems with sub-inch accuracy and make real time adjustments to the run path and end points,” said Christopher Higgins, Zimmatic product manager at Lindsay Corporation. “No other GPS lateral solution in the marketplace has the features and ease of use benefits that come with the Zimmatic 9500L GPS Guidance option.”

The team at TN&W Irrigation, a Zimmatic dealer in Manito, Illinois, recently installed a 9500L with GPS Guidance at the new Valent Midwest Agricultural Research Center. Opened earlier this summer, the 77-acre site near Champaign, Illinois, is dedicated to large scale testing of pesticides and biologicals for agriculture, seed protection and professional use.

“We chose the lateral system because, like most research plots, ours is square. The lateral provides the consistency we need,” said Dawn Refsell of Valent U.S.A. “We also like the ease of use. The system is very straightforward so one person can manage it. That’s important, because we don’t have a large crew here.”

Available for Zimmatic 9500L systems, the GPS Guidance option is ideal for installations where furrow or wire guidance are not suited or are difficult to maintain. Easy path management allows users to set virtual hose stops and/or service stops quickly and easily, and real time RTK correction ensures that the machine will always be where it should be.

Other benefits of the 9500L system include:

  • Dual Channel RTK delivers the fastest start-up times and most precise position accuracy.
  • It eliminates the need for costly repair or replacement of above ground guidance wires damaged by equipment or wildlife.
  • A single GPS base station can be shared by multiple 9500L systems within operational distance limits.
  • A simple retrofit, it can easily be installed onto any existing Zimmatic 9500L system.

The system installed at the Valent research site also is equipped with Growsmart® Precision Variable Rate Irrigation and FieldNET® by Lindsay for remote monitoring and control.

“Every plot is geo-tagged, so with GPS guidance and variable rate irrigation, we’re able to irrigate with pinpoint accuracy,” Refsell said. “With approximately 80 trials going on at one time, it’s very important for us to be able to control where we’re watering and how much we’re watering.”

The diverse research conducted at the facility includes pest management, such as how too little or too much water can affect herbicide performance. Researchers also will be looking at how the company’s products can help prevent moisture and nutrient stresses.

“It’s important that we know how our products perform in the field,” Refsell said. “This new facility and the technology we’re using will help us respond to the challenges faced by the farmers of today and in the future.”
