PathFinder ST-10

NEW for 2017 – Salford is expanding its range of steerable carts and fertilizer systems for 2017 with the addition of the Pathfinder 10-Ton cart and the ST-10 dual product applicator.  These will serve as flagship products in a range that already includes the successful Pathfinder 8-Ton cart along with the ST-6 single product and ST-8 dual product applicators.

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.

Available in a Skid Mount Package

The ST-10 is available independently as a skid-mounted system for use on 3rd party implements such as strip-till and applicator toolbars.

The polymer tanks are designed to be configured for multiple  applications. They will soon be available with liquid fertilizer or pressurized air system upgrade kits. In the case of the liquid upgrade, the ST-10 will have the unique capability to deliver liquid and dry product on the same steerable frame. The pressurized upgrade brings the highly accurate Salford air seeding metering system to the ST-10 and allow product to be delivered reliably to wider implements.

Heavy Duty Cart

The 5-link mechanical steering uses the Ackerman steering principal by which the inner wheel turns more sharply than the outer wheel.  This combined with a long hitch allows the cart to mimic the travel of the leading implement with a higher degree of precision. The high clearance axle allows the cart to follow application toolbars in standing crop without causing damage to the rows.  Large diameter tires allow for row-crop tracking while minimizing compaction.

A tow hitch can be added for towing anhydrous ammonia tanks as well.
