    No matter the field or crop conditions, it is important to be able to feed and protect your crops throughout the entire growing season. The all-season capability and performance of the STS Sprayers enable you to enter the field any day.


    • Gliding over crop with 1.88 m (74 in.) of underframe clearance combined with a narrow in-row crop package and smooth transition shields minimizes impact and crop disturbance.
    • Standard AWS ensures the rear tires follow the front tires, leaving only two tracks while turning.
    • Not only does the STS excel in late-season, tall-crop applications, but its balanced weight distribution with the tank full, empty, or anywhere in between and optional floatation tires enable it to perform in challenging field conditions all year long.

Strong steel composes the interior sections of these booms, providing strength and flexibility where you need it. The outer sections are made of aluminum, reducing overall weight and improving control. Special consideration for hose and plumbing routing improves operator visibility and overall boom cleanliness. Spray tips and nozzle bodies are protected from impact as they are positioned within the booms structure.


    • Improved visibility and lighter overall weight than previous-generation all aluminum booms
    • Available in a range of widths and nozzle spacings
    • Large range of application heights from 58.4 to 279.4 cm (23 to 110 in.)

  • Increased traction and programmable speeds with CommandDrive™ system

    The electronically controlled CommandDrive drive system provides an infinite range of field speeds and operator adjustability. The single hydrostatic drive pump provides flow to four variable displacement wheel motors. The system works automatically to continuously adjust they system to match target speed.


    • Real time traction control – CommandDrive monitors for wheel slip and diverts oil flow to send power to the other wheels. This system motors for slip front to rear, side to side, and crossways for maximum control and minimal slippage. Two predefined traction control settings are available (normal and severe) in addition to a custom setting that allows for manual control of both slip and de-stroke percentages.
    • Operator programmable speed ranges – Select the number of speed ranges from 1 to 20 and the first and last range top speed. This allows the drive system to be tuned for operator preference and field conditions.
    • Scroll wheel speed range selection – By scrolling the wheel on the back of the control handle, operators select the desired speed range. In addition to the scrolling feature, the scroll wheel can be pushed to rapidly change between spray and turn speed. Spray and turn speed can be set by the operator within the cornerpost display.
