Looks like you mainly used 1x4s, that saves a lot of weight.It's actually surprisingly light compared to what I expected. I don't have a way to weigh it exactly, but it's certainly a lot easier to shift around than a standard size feed bag or even a single cinderblock. Probably a bit more than what it's like carrying a couple gallons of milk, so I'm guessing it's somewhere around 20-25lbs. I've already moved it quite some distance a few times no problem.
