CenterLine 220 is a versatile and simple GPS guidance system for any field operation from Midwest Technologies. It is a compact, economical solution for growers interested in lightbar guidance. It features two modes of operation: straight line (parallel) and curved AB. The unit's large graphical display clearly shows off-track direction and distance along with swath number, ground speed, selected guidance mode and whether a return point has been stored. An alternate map page shows a bird's eye view of the vehicle position and heading in relation to the desired path.
In addition, CenterLine 220 is compact and designed for easy portability from vehicle to vehicle. Operational as soon as it is connected to a power source, CenterLine 220 is easy to use. Set-up is accomplished in just a few seconds, says the company.
The CenterLine 220 features a high quality internal WAAS compatible GPS receiver, with 5Hz position update, in a durable housing with a sealed rubber keypad. A small external GPS antenna connects to the unit and is mounted on the vehicle roof. Additionally, the unit provides a GPS derived vehicle speed as a Radar compatible ground speed signal for use with other control systems.
The new Swath Manager 5 from Midwest Technologies enables automatic on-off control of sprayer boom sections based on GPS positions. An accessory to the CenterLine lightbar, this model can improve the efficiency of product application by decreasing overlaps (see illustration).
Additional features of the Swath Manager 5 include easy manual override, compatibility with most sprayers equipped with up to five individual solenoid or ball type section control valves and its ability to work with most spray controllers.
The company has also introduced several new spray tips: the Turbo TwinJet (TTJ) has dual front and back flat spray patterns with a 60 degree spray angle. It is designed for use with fungicides, insecticides and herbicides. A new Turbo TeeJet 025 is for 0.25gpm at 40psi, especially good for fungicides; the Turbo TeeJet Duo (TTDuo) has a dual flat fan spray pattern for operating pressures of 15psi to 90psi and 60, 90 or 120 degree included angle between spray patterns.
