Well, Despite a very heavy top-dressing in mid April, My Bermuda Lawn remains lumpy enough to cause/contribute to the dreaded half-moon blade marks d/t the mower jostling up and down too much. At this point, I'm strongly considering rolling the lawn after a VERY HEAVY raining/watering, followed by a heavy core aeration to see if rolling helps any. I've read mixed opinions about the merits of rolling here on the site. If one were to do a .35 acre lot--what what be the optimal way to perform and recover from a rolling to level the turf and eliminate/reduce the lumpiness? How heavy a roller? what to pull with, etc. Thanks for the help!!
