See & Spray™ Premium factory installed on all Hagie™ STS Sprayers
Hagie STS Sprayer with See & Spray Premium The STS12 joins the STS16 and STS20 Hagie sprayers to be ordered with See & Spray Premium as a factory install. Making the complete STS lineup as the most advanced, versatile, agile and productive sprayer in the John Deere portfolio.
- Gain cost efficiency – With up to 50 percent spray volume reduction, this means significantly lower herbicide costs, fewer tendering stops, and more acres covered in a day.
- See & Spray Technology detects and targets to spray weeds in corn, soybean and cotton crops. Its evolutionary technology leverages John Deere's proven ExactApply Technology, which activates individual nozzles, to precisely apply material only when weeds are detected.
- When used with a strong residual herbicide program, See & Spray allows growers to protect fields by applying what they need where they need it, potentially reducing post contact herbicide use by up to 50 percent.
- Using less herbicide means using less water and creating less opportunity for drift, and that’s good for the land, water, and air that sustain us.
See & Spray Premium factory installed on Hagie STS Sprayers Enter the field any day with high clearance, all-wheel steer (AWS) and balanced machine weight
Hagie™ STS Sprayer in corn 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.

Precise on-target rate with the SprayStar™ control system
SprayStar solution keypad Covering acres is important and doing so with accuracy and precision is essential. The SprayStar solution control system found on the Hagie™ STS Sprayers makes sure every acre is covered precisely. The predictive pump control ensures target rates are accomplished faster, even in challenging dynamic conditions. Add the optional dedicated pull-on pump for fast and accurate solution tank loading and/or ExactApply™ for nozzle-by-nozzle control.
- Predictive pump control anticipates changes in flow to maintain target rate
- Electronic solution tank level indication
- Fast and accurate loading with the optional dedicated pull-on pump
- Optional eductor
- Optional ExactApply nozzle control
The solution keypad found on the cab entry ladder provides control of critical solution functions from the ground, eliminating the need to climb back into the cab during tending.

Cover more acres with the Hagie™ hybrid front boom
Hybrid sprayer boom Cover acres with confidence and control. The Hagie hybrid front boom lineup offers a lightweight yet durable design by combining both steel and aluminum. 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 all-aluminum booms on previous-generation models
- 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.)
- Three-direction, spring-applied outer breakaway
- Hydraulic main boom breakaway
- 18-m (60-ft) outer wing folded width on 27-, 30-, and 36-m (90-, 100-, and 120-ft) booms
- 21-m (70-ft) outer wing folded with on 40-m (132-ft)
- Locking connection between the inner and outer sections of the boom ensures rigidity

Boom Update
In model year 2023 the hydraulic cylinders have been updated along with surrounding structure to improve the folding and unfolding of the booms. Structural improvements have also been made to improve durability. The improved performance is especially beneficial when a drop system is installed.
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 monitors 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 corner post display.
