Hi lovemygreen, and a warm welcome to the forum. It's great to have you aboard. grin
The standard 6 blade reel in a Rover/SB 45 is used on a variety of different grasses with perfect results. I have used my Scotty (6 blades) on kikuyu, buffalo and couch with no problems. wink
Once again, :welcome: to OutdoorKing.
