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.

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 determine L/ha (gpa) and L/min (gpm).

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

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.

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 in a variety of configurations depending on the model and the producer's application needs.
