Take a look at post # 378 (
). There's a pic of the right one on my mower.
Yeah, the blades I had on there were Highlifts 1/4" thick 3 inches wide and it had the same curve in it and all. So I figured the washer wasn't needed.
First time using gator G6 blades today. Not sure what to think yet. Noticed the clippings are indeed a little more chopped up.
