Yesterday, you saw a process get done to the North course greens that has not been done in the 5 previous years that I have been the Superintendent. Truthfully, I’m not really sure when a version of this process was last done on these greens at Stow Acres. The machine is called a Rotadairon. A very detailed explanation can be seen here on their website. The service was provided by Mike Parks from Hillcrest Turf Services (http://www.hillcrestturfservices.net) located right here in Massachusetts. The purpose of running this machine over all 39 greens is to remove the “thatch” layer that builds up over the duration of multiple golf seasons. Although we aerate the greens every year, that machine only pokes holes and removes material 2″ on center (process can be read about here). Sand is then applied to fill the holes in. However, the Rotadairon, cuts into the surface approximately 0.5″ – 0.75″ over a 53″ width. It collects and removes all of the thatch material allowing for immediate air exchange to the roots and improved surface drainage. During the process yesterday, we mowed the greens, ran the Rotadairon, mowed the greens again to remove the very little debris left behind, blew off the collars, rolled the green, topdressed, fertilized, watered-in. The topdressing sand is a 1mm sand. This is used because it has a much larger pore space than thatch or traditional soil. The sand will allow for the bent-grass plants to continue to creep and become more dense. Overall, the achieved result is a firmer, faster, healthier putting green. With the right weather, the greens will be near perfect again by the weekend. Apologies for the short inconvenience. Below, are a few pictures and videos of the machine in action! See you on the course!
