Continuing to Core Collars

For the past few years, we've been trying to increase the frequency of collar aerification beyond the two times per year when the greens are aerified.  Collars tend to accumulate sand both from topdressing as well as from bunkers.  This can lead to "sand dams" or "collar dams" where water is no longer able to freely surface drain off the green.

We start by making a single pass with our aerifier:

The next step is to use one of our core harvesters to collect the plugs:

This is then followed by blowing off any remaining debris:

Lastly, we roll the collar:

Unlike when we aerify the greens, we are not filling the holes with sand, instead leaving them open.  Again, one of the goals of this process is to actually lower the collar a tad, so removing material and then rolling helps to accomplish this.
