Amsterdam, The Netherlands: Popularity for the Maredo GT 230 Core Dethatcher head of the triplex greensmower continues to sky-rocket.
According to the Maredo team there are a myriad of reasons why this new method of removing thatch has become so popular.
Marinus Reincke, Chief Executive Officer at Maredo, an Associate Business Member of the Asian Golf Industry Federation, said: “It is a clean process and the holes are perfectly cut. This guarantees a quick recovery, even when grass growing slows down in the autumn. More and more customers use the GT 230 until late in the growing season (with hollow or solid tines).
“It removes more material as we expect based on the number of holes. As shown in the picture, we see many cores but hardly all the holes. It looks like the cores have a larger diameter than the hole size. Mostly that is because the thatch acts like a sponge. So the removed core expands, while the thatch around the hole constricts (which helps the quick recovery).”
When you run these heads at mowing speed, a total of 2% of the surface is removed.
You can treat the same area two or three times (see the picture; it was done 3x at mowing speed), and/or reduce your ground speed, which increases the exchange rate up to 6%. To achieve a 6% exchange rate takes about 20 to 25 minutes per average green.
Reincke said: “Last month we updated our most popular hollow tine (#1823289). It is made from a better material, which gives a longer lifetime. With the Maredo GT 230, every tine punches more than 120,000 holes per hour. So all the 36 tines together produce about four million holes per hour.
“These four million holes equal 3.3 m³ (3.9 cubic yards) of removed material at 25 mm (one-inch) depth.
“Because the recovery is so quick and the damage almost nothing, most users do not top-dress afterwards.”
Quick and clean and better than spraying, not only is the Mardo GT 230 Core Dethatcher head ideal for removing thatch, but it’s also perfect for punching small holes in turf during summer time. These holes ventilate the turf (especially important when the turf is hot) and increase the efficiency of any irrigation and fertiliser programme.
Some golf courses use these solid tines once or twice a week and claim that the grass grows faster after the treatment. Most probably that is because of the oxygen entrance in the root zone. Such a solid tine treatment is fast and easy. No clean up is required and the greens are directly playable.
For this solid tining treatment, Maredo is introducing a new solid tine (#1812303).
Reincke said: “It looks like our needle tine (#1812301). But it performs better as we use better material, it is tapered and has a 3/8-inch mounting. It will replace the needle tine (#1812301) later this year.”
