Targeted spraying from Smithco
When spraying large amenity areas, precision and consistency when applying liquid fertilisers and chemicals are the key attributes of GPS-enabled sprayers. With regard to precision, individual nozzle control means sprayer operators will only spray inside designated boundaries, without wasting chemicals on non-targeted areas and negating the need for the operator to manually turn on and off boom sections when spraying.
Smithco were one of the first companies to introduce GPS technology when the Star Command system debuted in 2012. The ability to correct over spraying/over application brings additional environmental benefits, including reducing the usage of chemical inputs and more accurate distribution.
Smithco’s long-term partnership with TeeJet Technologies and their Dyna-Jet pulse-width modulation advanced rate control and dual nozzle system has resulted in ultimate control over spraying speed, pressure and droplet size. Spraying is consistent across any area regardless of terrain, shape or size of the surface area.
The Spray Star range features four self-propelled sprayers incorporating two alternative control options designated Star Command 1 and Star Command 2.
Star Command 1 features TeeJet Radion Rate Controller, Radion with Dyna-Jet Pulse Width Modulation which controls sections of the boom and allows automatic tip control with independent control of application rate, ground speed and pressure.
Star Command 2 with TeeJet’s Matrix 908 provides consistently less than 50 mm (2”) corrections, turn compensation, individual nozzle control and features industry-leading 250 mm (10”) nozzle spacing offering a 100% greater accuracy than competitors.
Both systems feature drift control, which allows the spray tech to select the droplet size on the fly.
Droplet sizes range from fine, medium, course and very course, and can differ between applications. If required, a larger droplet size can be specified to control the drift and still maintain the correct rate. Hydrostatic drive allows a constant engine RPM providing constant flow and pressure to the spray system for a consistent spray application.
As the largest capacity dedicated sprayer in its class, the Spray Star 1200 ensures that efficiency is optimised with a 757-litre low profile elliptical polypropylene tank, warrantied for life. The high performance, cost-efficient pumping system features a self-priming and corrosion resistant, stainless steel centrifugal pump generating 341 litres/minute and providing the capability for high flow applications with superior agitation. The cab-forward design provides superior visibility, handling, and operator comfort.
