For over 15 years, Gareth Rosvall has relied on Greenback spider irrigators to manage effluent irrigation across the Hopkins Group eight dairy farms in the Manawatu region.
In an industry where reliability, simplicity, and performance are critical, the Greenback Spider has proven to be a cornerstone of Gareth’s effluent management system. One of the key reasons Gareth continues to choose Greenback Spider irrigators is their user-friendly design. With multiple team members across several farms handling irrigation duties, having a system that’s simple to understand and operate is crucial. Staff training is straightforward, and the intuitive design means that even new or seasonal workers can get up to speed quickly minimising errors, reducing downtime, and ensuring effluent is applied correctly every time. The five-speed gearbox on each Greenback Spider irrigator gives Gareth and his team the ability to fine-tune application depths to match the variable soil moisture conditions experienced throughout the year. Whether it's drier conditions requiring deeper application or wetter periods calling for a lighter touch, the adjustable speeds allow for greater control and smarter irrigation decisions directly benefiting both soil health and pasture growth.
One of the biggest benefits Gareth has seen is in effluent storage and overall management. The ability to irrigate with precision means that effluent can be applied more frequently and in optimal conditions, which significantly reduces the reliance on long-term storage. By spreading smaller amounts more often and avoiding over-application the risk of runoff, ponding, or non-compliance is minimised. Across eight farms and over 15 years, the Greenback Spider irrigators have consistently delivered the performance Gareth Rosvall needs. Their simplicity, durability, and versatility have made them a trusted tool for his operations.
If you’re looking for an irrigator that’s easy to use, precise, and built to last—just like Gareth Rosvall—you can count on the Greenback Spider.
