It comes down to intent - if you're mowing because you need to, that's a warm season mowing session. If you're out there with the purpose of winter weather preparation, that's a snow mow. That would not count towards your 2024 seasonal mowing total.
Others in the thread might disagree with my assessment, but when you're the mowing king, I reserve the right to make and amend rules as I see fit, and to the benefit of myself.
