A regular light grooming/ vertical mowing treatment is important to keep greens is good shape. The amount of organic matter can be controlled, and unwanted growth gets removed giving precious grass room to grow. The problem with vertical mowing or grooming is the visual slits regular groomers will produce. The slits will affect ball roll on greens. MAREDO came up with a solution: The GT190 Fraze-Groomer. The MAREDO GT190 heads are equipped with unique technology. The main shaft reverse rotates unlike any other groomer. Besides that, the blades are placed on a slight angle on the main shaft. This results in leaving a clean pattern with short slits. Each tip of the blade will produce a short and hardy visible slit. Incorporated brushes will help leaving a clean surface ready to play on right after!
