Demonstrating the AccuPro 360ST’s exceptional spread pattern

At ICL, we developed the AccuPro 360ST pedestrian spreader, featuring advanced SmartSpread™ technology, to set a new standard in spread consistency and efficiency.

To determine the ideal settings for all our granular fertilisers with the AccuPro 360ST, we worked with a specialist company known for their expertise in spreader testing and calibration. The results, available on our spreader settings page, ensure users have the most accurate settings for effective application.

Following the same process as the spreader testing, we conducted live demonstrations at our Turf Science Live events, showcasing the AccuPro 360ST’s superior performance in real-world conditions.

In front of customer groups, the AccuPro 360ST consistently outperformed a competitor spreader by delivering a more even, reliable spread pattern.

The Spread Pattern Demonstration

To compare the AccuPro 360ST’s field performance against a competitor spreader, the demonstration was designed to highlight differences in spread pattern quality under typical usage conditions. Here’s a breakdown of the process:

1. Tray Placement: Two sets of six collection trays—one set for each spreader—were positioned along each spreader’s path. Each set included three trays on either side of a central line, allowing us to capture the granules as they were applied. Each tray had inserts with 36 individual collection compartments, resulting in a total of 216 data points per spreader.

2. Controlled Spread: Both the AccuPro 360ST and the competitor spreader were filled with granular fertiliser and operated along the central line at a consistent 5 km/hr, the recommended speed to ensure uniform application.

3. Granule Collection: As the spreader dispersed granules, each tray and compartment collected a sample of the spread pattern, allowing us to measure granule distribution consistency across the full coverage width.

4. Sample Transfer: Once complete, granules from each compartment were transferred into test tubes to precisely analyse the spread consistency and compare granule volumes across trays.

5. Visual Analysis: The contents of the test tubes provided a clear, side-by-side visual comparison between the AccuPro 360ST and a competitor spreader. The AccuPro 360ST’s even distribution was clear, with fewer peaks and troughs in its spread pattern.

Results

The demonstration showed that the AccuPro 360ST provides a uniform spread pattern across its full application width.

SmartSpread™ technology, located under the hopper, optimises distribution by allowing users to adjust the spreader for each application. Larger, heavier granules—such as ProTurf or Sierrablen Plus—are directed toward the centre of the impeller to achieve the necessary centrifugal force for even coverage, while applications of smaller, lighter granules, like SierraformGT, are directed closer to the outer edge. This results in an optimal spread pattern, helping to promote uniform turf health.

In contrast, while the competitor spreader was well-built, it delivered a less consistent spread pattern, with significant peaks and troughs that could lead to uneven fertiliser application.

In conclusion

A uniform spread pattern reduces waste by applying only what’s needed, lowering costs and supporting sustainable practices by reducing nutrient runoff.

For turf managers focused on precision, sustainability, and cost-effectiveness, the AccuPro 360ST is a reliable and efficient choice.
