Beyond basic topdressing applications, the 920E GreensGroomer makes a significant improvement in the quality of your greens prior to your mowing efforts. Brushing greens ahead of the mowers will remove dew, stand the grass blades up, and create a precise consistent cut.
Grooming will remove much of the grain from putting surfaces, good thing. The result of proper grooming will demonstrate characteristics of truer and smoother putting surfaces. As a result from the superior mowing, the height of the cut grass can be grown higher resulting in a raised and still maintain the desired green speed with less stress to the plant. Older leaves are raised up by brushing and are cut off. This opens up room for newer, more disease tolerant, younger plants to emerge. By removing the older, weaker blades, you have also removed the material that is more likely to be attacked.
Verticutting in the Spring and Fall is an acceptable practice, but under Summer stress, grooming is superior for a couple of reasons. First, you can groom ALL Summer without damage or stress to the plant. Second, reel to bed-knife is the only clean cut there is for turf. Verticutting can wound leaf blades and does not seal off as fast as during a Groom and Cut.
Frequency should be 2-3 times a week for mid to higher end clubs. For smaller clubs, only brushing once a week will still provide a major difference in play-ability.
Brush 90 degrees to the greens mower each day you brush to achieve the optimal cut. Cutting with the brush direction is very aggressive and going against the brush direction is conservative.
Brushing should follow a “Zamboni Style”, half of the green brushed in one direction, and the other half in the opposite direction. Once the four rotations of brushing/mowing have been performed, start in the original position, but brush in the opposite direction from the first set of brushing.
The photo shows 3 cuts on the same bent-grass green. The process was cut, brush, cut, brush, cut. Although a productive grooming schedule may be to groom once per week prior to the first cut, we have exaggerated the demonstration to show the dramatic effects of multiple grooming’s.
After the first cut, the green stimped at 8’9″. After the second cut, the green stimped at 9’4″. After the third cut, the green stimped at 9’9″. Without changing the height of cut on the mower, each grooming and subsequent mowing produced nearly the same amount of clippings.
