I don't have anything to do with golf courses and maintenance outside of replacing divots! I was wondering for you guys that are involved what you would say has been the biggest advancement in course upkeep/maintenance/whatever in the past 30 years or so. I'm into restoring old Farmalls and noticed an ad for a Farmall Cub and it showed it on a golf course pulling a set of gang reels. It also showed an old Cub Cadet with a front mounted greens mower and thought, you'd never see that now... This was circa 1962ish.
