Solution pump
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.

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 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.
