Features
Hagie™ STS Series engines
John Deere PowerTech™ PSS 6.8-L (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 couple 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.
Hagie is a trademark of Hagie Manufacturing Company, LLC and similar to John Deere branded equipment, JohnDeere will also support Hagie equipment.

Solution tank, pump, and pump switch
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 determineL/ha (gpa) and L/min (gpm).
Solution tank
Solution tank | Sprayer model | Tank capacity | Tank type |
| STS10 | 3785 L (1000 gal.) | Stainless-steel tank |
| STS12 | 4542 L (1200 gal.) | Stainless-steel tank |
| STS14 | 5299 L (1400 gal.) | Stainless-steel tank |
| STS16 | 6056 L (1600 gal.) | Stainless-steel 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 andalso dispenses fluids through the agitation and rinse systems.
Solution pump switch
Solution pump switch 
Machine control display - Home 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 spray booms
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.
The spray booms are offered ina variety ofconfigurations depending on the model and the producer's application needs.
