I have a single place Rackem. Until I saw your pictures I couldn't figure out what the problem was. I totally understand now. The top trimmer has to come out first and then you have to work your way down the rack.
That does suck and it's unacceptable. Just an FYI, Lawnsite's pages are indexed (made available on Google) every couple of hours. Whatever you write about them here will be available on Google searches in a few minutes. So if you say that Rackem sucks it will warn others on Google.
