We've had an original Ford 3pt. scoop for about twenty years now and it's a handy item to have. Now, it's not the same as a FEL by any means, but it will move a surprising amount of dirt from the relative ease of the tractor seat.
A few years ago we cleaned out a small dirt tank with it behind a Ford NAA. Yeah, it was slow going but we had the time, we enjoyed ourselves, and it saved a lot of money versus hiring a dozer at $50+/hour.
Seriously, for what they cost they are one of the most useful and cost-effective items I've ever used.
