We're The Planter People. PLC (Programmable Logic Controller) control system. The SRES Classic Aire Controls is the next logical step from the Classic Controls. The Classic Aire is designed to meet all the expectations of a precision planter for the same price as a cone planter. Unlike a cone planter, which will always be a cone planter, you can always upgrade a Classic Aire. A PLC (Programmable Logic Controller) is used as the control mechanism. Seed spacing is controlled by a mechanical transmission and the number of holes on the seed plate. All gates and valves are controlled by air cylinders. The Classic Aire adds staging gates and alley wipers for a more consistent alley than the Classic. The Classic Aire Planter has many different tripping options, manual trip, cable winder, check heads or GPS.
