This morning, we are punching some more 1/4" tines on greens 1,2,15 and 16. Due to extreme shade, these tend to be our most challenging greens. A few weeks ago, we ran our air injection machine across these 4 greens and despite double rolling afterwards, we experienced a small amount of scalping after 2 weeks of mowing. This is what caused the minor thinning your seeing in a couple areas. this process of 1/4" tines will help smooth the surface and and also work to promote recovery in these areas.
