They are really tight for space so they pack them in tight. From that picture it looks like they have it all calculated to fit them in. I haven't been in the yard in the winter so I don't know how much elbow space there is for cleaning and polishing. I don't think there is any electricity in the back of the yard anyway so not sure how much polishing they can do, maybe with a really long extension cord. They almost look like water drops on a windshield aligned with the air flow.
