content: It took me 10 minutes to assemble, including the grass catcher. I was outside mowing in 15 and done in an hour.It's a bit heavier than I expected and the grass catcher makes it trickier to maneuver than my old electric, but I like it. It cut through my thick, ugly crabgrass on the lowest setting in no time. I'm looking forward to trying it with the mulcher rather than the grass catcher, just to see the difference. (But my lawn's so short right now, I think it will take a while.)
