This thread is what I needed to read. I currently have a 7 x 16 enclosed and it's a pain to fit everything I have. Looking to purchase two aerators next year and am not sure how this is going to work for having everything with me.
As far as a reply for the person seeking information, always plan for expansion. Buying bigger than what you need is going to save you down the road. I estimated a 8.5 x 24 foot enclosed trailer. I also included building a small work bench at the noise of the trailer. At that width I'm sure you could turn all the mowers without baggers sideways, if that option saves on space.
