What is the average weight for a 14.1 welsh section d?

A section D Welsh Cob tends to be a bit heavier in build, however the overall conformation of the horse will affect it's weight more so than just its height. If the Section D is a bit more narrow in build, then it will likely weigh less than a broader built horse of the same height. That all said a Welsh Section D typically weighs in the 750 to 1000 pound range ( 340 kg-453kg or 53 st - 71 st.)
