A recap of what we did.....
A contractor performs this step with 4 machines that can get roughly 8 inches below the surface with 1/2" diameter solid tines. This addresses the part of the greens profile that our machines never see. It helps to improve the rate at which water moves through the soil and breaks through layers that can impede root growth and turf health. We used to do this every other year, but the greens are aging and can benefit from it more often. We combined it with our core aeration so you wouldn't have to deal with two separate aerations.

We followed the soil reliever with our roller just to firm up the surface prior to topdressing and core aerating.
We used about 80 tons of sand in an effort to fill the holes. We did this before core aerating so we wouldn't be driving a heavy machine over a soft freshly aerated green.
We used our new Pro Core 648 aerator with 1/2" diameter tines set to 2.5" depth. This removed some of the excess organic matter that we are constantly trying to keep in check. The machine pulls the cores to the edge of the green where they are then shoveled up by staff. We hauled the cores to our wildflower beds where they will be spread out.

We brushed the sand multiple directions to try and get it into the aeration holes.
