Devoisi, love the grooming attachment!! I have Plateau Couch which is a strong laterally growing couch and would find this attachment very useful, would use is quite often and would set a devoted machine up with the attachment for regular use as you have said you will do!
I am no guru on turf management but for those who arn't familiar with high quality maintenance of turf, Devoise has built a domesticated "verticutter" for the most manicured lawns.
I have attached a link to a great article that explains the use of a verticutter.
Here is an extract;
"It is recommended that verticutting be done several times a
month, if possible, especially during the spring and fall when weather conditions are favorable. Some superintendents verticut as often as once a week, going in two directions each time"
"The secret of this operation is to set the units so that the blades are very shallow, just nicking the surface of the turf. If you can see the grooves the machine is making, it is cutting too deeply. Many golf course superintendents
use 1/16 inch as their guide for this operation"
Here's the link..
