Because of these problems, some aftermarket companies say that growers who want the broadest range in task controllers may have to settle for a second display in the cab until the standard catches up with growers' needs. That could take another three to five years, says AutoFarm's Malott.

He predicts that, if and when the industry arrives at a single display that can do all functions, aftermarket companies will find their niche in building controllers that work off that one display. “In the end, it will be a competition among task controllers if everything plays out in the best interest of growers,” he says. “And the terminal will be just another device that is built into the tractor to provide the interface for those controllers.”

OEMs maintain that a one-display solution is possible, especially as the technology advances and is able to incorporate more functions at a lower cost. Matt Danner of John Deere says, “ISOBUS electronic compatibility is comparable to what Pioneer hydraulic couplers were 20 years ago, and look at the difference that made in the industry.”
