Why Use Reid & Harrison Services for Your Yardmaster® Stirrers?
With decades of experience and local know-how, Reid & Harrison Services are specialists in integrated effluent solutions. We understand the unique challenges of New Zealand dairy farming and supply proven Yardmaster® equipment that works as a complete system — from stirrers to pumps, separators, and automation. When you work with us, you get practical solutions, reliable gear, and a team that stands behind every installation.
Why do you need a Yardmaster® Effluent stirrer?
Over time, solids can settle at the bottom of effluent ponds and storage tanks, forming dense layers that are difficult to remove. Yardmaster® stirrers prevent this build-up by maintaining constant movement throughout the pond, blending solids and liquids evenly to produce a consistent slurry. This not only improves nutrient distribution but also reduces blockages, pump wear, and costly downtime.
