Constructed on a heavy clay soil profile, the two 18-hole courses at Welwyn Garden City’s Brocket Hall Estate fell victim last year to what arguably has become one of the biggest challenges for fine turf managers – worm casts. Without available curative chemistry, Golf Course Manager John Moorhouse turned to his local dealer for advice who recommended the Redexim Top-Brush. Three months on from taking delivery, the Top-Brush has proven itself to be a true multi-tasker – not only tackling the issue of worm casts but leaves and surface moisture too.
Quintessentially British in their design, but very different in terms of their challenge to golfers and greenkeepers alike, the Palmerston and Melbourne courses are overseen by a dedicated team of 10. “The combination of our heavy soil and milder, wetter autumns has seen a huge spike in the number of worm casts we’re seeing” explains John. “I spoke with David Fisher of George Browns to see if there was a way of removing the casts prior to cutting. He straight away organised a demonstration of the Top-Brush.”
The Redexim Top-Brush is a six-metre-wide poly-brush, comprised of three sections, that can quickly and effectively rid large areas, such as fairways, of worm casts, organic matter and dew. Because the brushes can rotate in or against the direction of travel, it can be used to remove lateral growth and stand the plant upright – contributing to better airflow into the canopy and a cleaner quality of cut.
“It’s really easy to hook-up via the 3-point linkage and it’s quick and straight forward to adjust the rotation direction and working depth. It has not only done exactly as we hoped in clearing surface casts, but it also played a major part in leaf clearance on the heavily tree-lined Palmerston course – using the brushes anti-clockwise to lift and move the leaves and other debris such as pine needles out of play and giving us a great, clean finish.”
When used with clockwise rotation, John has been impressed with the Top-Brush’s ability to remove dew and improve course presentation. “It has given us a quick and effective method of reducing surface moisture, especially early mornings, not only contributing to improvements in plant health but giving us a beautiful striped finish on the fairways.” He concludes, “As we head into the spring, in addition to all of its existing uses, we plan to use the Top-Brush to help with incorporation of topdressing material. The versatility demonstrated by this piece of kit means it has done exactly what we hoped for, and so much more.”
