More Accurate Fertilizer Blends
ST-10 models can carry two separate commodities with their 60/40 split tanks. Blending is done right at the meter, rather than in the air line. This ensures the most accurate blend possible. The ST-10 has 2 separate tanks.
ST-Series applicators use peg roller meters, which excel at metering seed or fertilizer. Compared to auger metering these rollers offer greater accuracy, are less susceptible to plugging, are easier to change and do not grind product. Peg rollers are equipped with brushes for self cleaning. Low rate rollers available for cover crop and micro nutrients.
ST-10 – Poly, Individually Scaled Tanks & 4-Section Metering
The ST-10 offers new capabilities and new level of refinement. Its new, light weight polymer bins are translucent and allow an additional visual indicator of the bin level along with standard bin level sensors. The overall capacity of 10-tons of fertilizer is split between a forward 4-Ton tanks and rear 6-Ton tank – both of which can be scaled individually. Large, easy to open lids and sloped sides makes filling with tender trucks simple and efficient.
Snap-in meter rollers, spring-loaded gates and a full-width removable panel below the air manifold take the hassle out of unloading. The meter rollers themselves are now an accurate pegged style rollers similar to Salford’s air seeding systems. The new rollers offer a wider range of application rates and are available with standard and low rate peg sizes.
The new 4-section metering system retains the reliable, low maintenance and user-friendly aspects of the Valmar-designed ST6 and ST8 with the added ability to turn up to 4-sections per product on or off based on application maps. An optional ISOBUS control system allows connectivity to ISOBUS compliant cab consoles*. Mechanical engagement of the meters is achieved via electric clutches; a proven approach that has already seen extensive use on other Salford Valmar products.
Both metering systems deliver product to a single funnel that drops in to a common venturi air stream for the highest possible blending accuracy and efficiency. There is no need to run two sets of air lines to the application knife as all the blending happens right at the metering system. The air manifold and funnels are only connected to one metering system to maintain scale reading integrity.
The number of air outlets is determined by the funnel/air manifold assembly, which can be easily changed by simply unbolting it from the metering system. Updating from a 12-outlet to 16-outlet system can be achieved in a matter of minutes. A 20” fan driven by a 12cc hydraulic motor spins at up to 5900 rpm to provide plenty of air at high rates. By maintaining a set pressure in the air plenum behind the venturi manifold, a constant, reliable airflow can be achieved regardless of the number of outlets.
Section Control Ready
ST-Series models are capable of ISOBUS compatible section control. The ST-6 and ST-10 metering system is split into four sections for the most accurate, cost effective application.
