Rolling/Smoothing Hay Fields

Saw a video of a guy rolling his fields with a big drum contraption to help smooth them out after the season. Just curious if it’s something worthwhile to consider? If so, what equipment do you use, time of year, special conditions that make it work better, etc?

I make every attempt not to rut them up in the first place but from time to time notice a rough spot and it crosses my mind. Maybe youll do more harm than good, I don’t know. Can’t say I’ve seen anyone in my area attempt it, but we aren’t really in hay county. My mind wonders over winter.
