Weekly Photo Challenge: Abandoned

We routinely walk a trail with the dogs near our home, but we were recently disappointed to arrive there and discover it was closed for trail maintenance.  The dogs are always excited when we go for a car ride, undoubtedly anticipating the walk.  So we certainly didn’t want to return home with dejected pups.  We instead drove a bit further to another nearby trail.  I had my camera in tow to capture the recent snowfall and discovered this abandoned farm equipment off one of the trails.  As you can see, it has certainly been here for quite some time! Long enough for a tree or two to grow up through it!  I wonder what circumstances left it here?
