He was a beauty, wasn't he?  He was a Fresian stallion who recently passed away.  Here's a link to the Fresian Society:

Also, take a look at the Belgians in "For Richer ... For Poorer" with Tim Allen and Kirstie Alley.  The film was funny but the Belgians are spectacular and you can get an idea of hindquarter proportions.

Draft horses use their haunches to power the pull and their forequarters to drive the pull.  It's a complicated mechanism until you actually watch them.  It's amazing what those animals can do.
