Top dressing greens

I've been top dressing greens, I scarified greens first to get rid of lateral growth, remove dead matter, remove any seed heads if any are present but help top dressing get in around crown, holding grass up more vertical & today's top dressing will become root zone of the future after the top dressing i will brush & drag mat sand into grass sward, I will be doing this on a regular basis of 3-4 weeks doing this will help with smoothness & improve root zone over time.
