Operation Introduction Grooming is performed in the turf canopy above the soil level. Grooming promotes vertical growth of grass plants, reduces grain, and severs stolons producing a denser turf. Grooming produces a more uniform and tighter playing surface for faster and truer action of the golf ball. g010436 Figure 20 Verticutting is a more aggressive cultivation technique designed to remove thatch by cutting through the turf canopy and into the thatch/mat layer.

Setting the Height/Depth of the Groomer The groomer blade height/depth can be set using the following chart, figures, and procedure: Rear Roller Spacers Required Height-of-Cut (mm) 0 1.5 3.0 4.8 6.3 1 mm mm mm mm Height-of-Cut (inches) 0.06 0.12 0.19 0.25 Groomer Arm Position Height-of-Grooming Range (mm) to to to to 1.5 3.0 4.8 6.3 Height-of-Grooming Range (inches) inches inches inches inches A A B B 0.7 1.5 2.2 3.0 mm mm mm mm 0.03 to 0.06 inches 0.06 to 0.12 inches 0.09 to 0.19 inches 0.
Testing the Performance of the Groomer Important: Improper or over-aggressive use of the grooming reel (i.e., too deep or too frequent grooming) may cause unnecessary stress on the turf leading to severe greens damage. Use the groomer cautiously. It is important to determine the performance of the groomer before putting it into regular use on greens. We strongly suggests that you use a formal test procedure. The following is a practical way of determining the proper height/depth setting: g016235 1.
Maintenance Note: On multiple passes (i.e., double and triple cutting), the groomer will continue to penetrate deeper on each successive pass. Multiple passes are not recommended. Cleaning the Grooming Reel 5. After you test the performance of the groomer on a test green and obtain satisfactory results, you can begin grooming on the playing greens. However, each green may respond differently to grooming. In addition, growing conditions are constantly changing.
Inspecting the Blades Replacing the Grooming Reel Inspect the grooming-reel blades frequently for damage and wear. Straighten bent blades with a pliers. Replace worn blades; torque the lock nuts to 42 to 49 N·m (31 to 36 ft-lb). When inspecting the blades, check to see that the right and left blade shaft end nuts are tight. You can remove the grooming reel to replace individual blades or the entire shaft. Remove and replace the grooming reel shaft using the following procedure: 1.
