Mowing 5 acres with a 2014 Z970R 72" 7 Iron Pro. Central Ohio Blue Grass. Last season was extremely wet. Seems like this season may be the same. At least starting out. Never caught up last season, leaving grass at 6" + with record rainfall, wet fall season, & wet winter season. Using original blades and chute. Wondering if any other blades would be helpful for getting through extremely high, wet grass. Any suggestions appreciated.
