Increased demand for Avadex granular applicators to fight against blackgrass has resulted in the launch of the Horstine Cascade. A similar design principle to the company’s existing TMA4, the Cascade is a larger boomed applicator with widths available up to 24m and a larger 1500 litre hopper.
Application accuracy across the full working width of the boom is guaranteed using four application sections each with hydraulically driven metering, where each distribution outlet on the boom is fed by its own individual metering rotor. Despite the added complexity of this system when compared to using one large rotor and a distribution head to supply the outlets, Horstine prefer to use the individual metering system as it removes another variable that could introduce uneven application.
Product is delivered from the metering rotors to the distribution outlets via a pneumatic system, featuring a high capacity hydraulically driven fan and individual venturis for each outlet. The layout of this system is such that once the product is metered into the venturi, it travels along a perfectly straight pipe, with no bends or kinks to delay it along the way.
This straight path is created by using a hydraulic vertically folding boom, which opens to be perfectly flat when in use. The need for flexible pipe around the bends is removed and the boom is kept away from the cab, something that is preferable for a tractor mounted applicator.
Distribution outlets are spaced 1m apart, allowing the Cascade to be made available in widths other than 24m, such as 15, 16, 18 and 20m, and allowing precise application of products in farming systems up to 40m in width. This new spacing has been extensively tested during recent years on other models of Horstine applicators to ensure patternation is perfect.
ISOcan rate controller utilizes RDS technology to maintain application accuracy and allows Horstine to control the four metering motors individually, creating four application sections on the machine. Automatic section control is also an option to minimise overlaps and misses.
All of the features integrated into the new Cascade applicator are designed to maximise application accuracy as well as to apply a range of other products such as slug pellets, granular fertiliser and small seeds.
Cascade has many advantages over a spinning disc system used for applying slug pellets. For example it uses a double overlap spread pattern from its distribution outlets guaranteeing cover over the whole of the area, but without ever propelling product further than a metre. This dramatically reduces contamination risk to hedgerows and watercourses. Boomed application also has an advantage over spinning discs for granular fertiliser application, especially in windy conditions, which widens the application window for growers. Auto section control gives growers greater control at the headlands too, reducing the chances of lodging and ensuring fertiliser is not wasted.
Cascade can also be used to efficiently broadcast seeds either before harrowing in, or into a standing crop before harvest.
