Lawn thatch/powered hollow tine

My lawn is 27 years old and I feed in in spring & autumn, using feed & weed. Very few weeds & little moss. I used powered roller type rotary mower, set to medium height, not too tight. Problem is that tips of grass are growing on brown shoots of 2", leaving footprints. Lawn looks better than it actually is. Is it too late (end Nov) to use a powered hollow tine machine? Or would spring scarifier be better? TKHO, Limerick, Co Limerick Posted: 25/11/2017

A hollow tine machine is used to relieve compaction, as on golf greens. You have rightly identified grass thatch as the problem and this would be best alleviated by scarifying in spring, when you could also top-dress with some fine soil, if you have it, and oversow with seed of the same kind of grass you already have.
