I am obviously new to bermuda grass greens. Do your greens go completely dormant? What size and type of tines?
Are you having to roll them out afterwards? If so with roller, walkmowers etc. ?
No, not completely dormant, but definitely not growing. But, this is our high play season and non-overseeded. We use 5/16" x 8" tines and go in about 6". We roll right behind and can get 4-5 done before play in the morning using a Soil Reliever model 54. We see no heaving with this process and equipment we use.
I doubt your greens go fully dormant. The stolons and rhizomes beneath the surface are still alive, although probably not growing. Keeping an aerobic profile is part of the equation. Solid tining throughout the winter months is the key. Helps keep root and crown diseases at bay by providing the necessary oxygen for the plant to survive.
Of course you are way further north than I am. But, i think if you do a test green, you'll see no adverse effects, and probably gain some early green up during a warm spell in the spring.
