For me, with the Kubota plastic/glass unit, I installed it by myself and have taken it down, off, folded, and removed the thing for repairs and getting into a barn/shed to clean out goat poop on a pretty regular basis.......I am 68, arthritic (100% VA disabled), and though in pretty good health am not just out pulling buses down the road with my teeth...................BUT.......Yes, the thing is cumbersome, not heavy, but of a size, shape, and mass that is hard to manipulate......VERRRRRY doable for me.....
Not even pushing the Kubota stuff, just because I have it.......there is LOTS of stuff out there that will and can meet your needs. Really, NONE are better than the other. Mrs. D. gave me mine for a Christmas gift and I am not one to look at horse in the mouth and kick it out. So......for me, it's what I have, am glad to have it, and yes, it has the merits of being able to be repaired, again and again, and again and then the repairs themselves.................God bless......Dennis
