I have an Echo PE-2400 stick edger and I emailed Mowtownusa.com and asked which replacement blades they recommend. I received an email and told me the Stick Edger Blade 8" length, 1" center hole, 2" Wide, .125 thickness works best. My question though is the post on my edger is only 3/8" so with a 1" center hole won't that blade wobble? What do you guys think or recommend? Thanks!
