The TeeJet 844 Sprayer Control offers spraying advantages not found in other controllers. Designed with simplicity in mind, computer-controlled spraying has never been so easy. Simply set your target application rate and the unique VisiFlo display on the 844 helps select the right TeeJet tip for the application. Once spraying begins, the large display shows application rate, volume sprayed, system pressure, sprayer speed and area covered.

The built-in planning tool on the 844 automatically displays the speed needed to achieve the target rate with the specified tip. It will also calculate the pressure necessary for achieving the target application rate when the speed is entered.

The 844 is available in a complete package with the valves, cables and sensors needed to put together a total sprayer control system, or as an individual controller.


GPS/printer compatible with optional 39488 GPS upgrade kit.

Color-Coded programming helps you select the right TeeJet spray tip for your application.

Quick calibration can be done with icons that prompt the operator for information during calibration.

Information at a glance on a large backlit display that shows application rate, volume sprayed, system pressure, sprayer speed and the area covered.

Quick changeover allows operators to apply crop chemicals or anhydrous.

Five individual boom switches allow boom control from the operator’s seat.

Pressure or flow-based regulation allows operators to quickly switch between control methods.

Optional communications upgrade gives the operator easy and accurate record keeping abilities. This allows printing of application records and interfacing with GPS variable rate systems.

Boost mode allows the operator to adjust rates on-the-go to increase or decrease the target application rate in 10% increments.
