Ame G Crystal Lake , IL August 16, 2016 Appliance: Model KITCHENAID 6QT PRO Beater was always badly scraping the bowl planetary looked like it was dropping out of the mixer you could actually push it back up into the mixer head After watching a quick video I decided this was something I could fix myself. I took it all apart, replaced the entire planetary head( seriously easy and only like $25-$30) put everything back together and my 6qt kitchenaid pro works good as new! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
