John Deere PowerTech™ PSS 6.8-L (415-cu in.) engine

PowerTech™ PSS 6.8L (415-cu in.) engine

Beginning with model year 2019, the Hagie STS10 and STS12 Sprayers utilize the John Deere PowerTech 6.8L (415-cu in.) diesel engine. This engine offers 208.8 kW (280 hp) with a peak power of 223.7 kW (300 hp) in the STS10 and 223.7 kW (300 hp) in the STS12. The reliable performance of these engines couples well with the drive system on the STS Sprayers to provide the operator excellent power on demand.

Engine location

Rear-mounted engine

The rear-mounted engine keeps constant weight to offset the spray boom and leaves space in the center of machine for the varying weight of fuel and rinse tanks. This allows for better coolant airflow and reduction of cab noise.

Connected Support technology

When you buy John Deere equipment, you expect reliability. You also know that problems can happen, and a product is only as good as the support behind it. That’s why John Deere equipment is prepared with technology that senses potential issues and can alert you and your dealer promptly—in the cab or anywhere you are.

John Deere Connected Support is a revolutionary change to support that leverages technology and the connectivity of JDLink™ telematics to prevent downtime and resolve problems faster. These tools decrease downtime by an average of 20 percent, enabling faster responses to unexpected problems and reducing technician trips to your machine. For some issues, unplanned downtime can even be prevented altogether through prediction of the issue.

With your permission, John Deere Connected Support:

• Keeps you running by monitoring machine health and promptly alerting you and your dealer of issues
• Saves time by remotely viewing in-cab displays, reducing trips to the machine
• Reduces or even eliminates technician trips to a machine through remote diagnostic and remote software reprogramming capabilities
• Connects experts with the information needed to respond to downtime faster and prevent it altogether

With more than a decade of experience leveraging connectivity to solve problems, no one else has the experience, tools, and knowledge to keep you running as John Deere and your John Deere dealer can. Connected Support is an in-base feature on all John Deere products with factory- or field-installed JDLink.

The solution system is a constantly monitored, continuously adjusted, computer-controlled system. The cab-mounted digital spray system console receives information from various inputs to help determine L/ha (gpa) and L/min (gpm).

Solution tank

Solution tank

Solution pump

Solution pump

The Hypro® 9306C-HM1C-BU solution pump (located beneath center of machine) is a centrifugal-type, hydraulically-driven pump that is controlled by the solution pump control valve and the spray system console. It comes with silicon-carbide seals, 7.6-cm (3-in.) inlet plumbing and 5.1-cm (2-in.) outlet plumbing.

The solution pump draws solution out of the tank at the rate determined during calibration. It dispenses solution through the many valves and hoses that make up the spray system and also dispenses fluids through the agitation and rinse systems.

The solution pump switch is located on the side console and is used to turn the solution pump on and off.

NOTE: When the solution pump is on, a solution pump indicator (located on the machine display home page - field mode) will be illuminated.

STS Series Sprayer booms

The spray booms are controlled by an electrohydraulic system. This system consists of operator-manipulated switches (located on the side console and the hydrostatic drive control handle) and hydraulic cylinders (attached to the booms), which provide lift, level, and horizontal extension. Hybrid booms are available in widths of 27.4 m, 30.5 m, 36.6 m, and 40.2 m (90 ft, 100 ft, 120 ft, and 132 ft).

The spray booms are offered in a variety of configurations depending on the model and the producer's application needs.
