Our late season deep tine aerification was moved from November to mid September. So that means we did not get a big load of topdressing on the greens late in the season this year. So we decided to put one on just before full on winter set in. These pictures show the sand on half the green and the buffalo blower being towed behind a cart working the sand into the green. For those of you interested in the reasons we top dress greens please check out this link: http://turf.lib.msu.edu/gsr/1970s/1974/740317.pdf It is an older article but informative.
