Good looking trailer Mike

But I just got to know cause it drives me nuts why do some call these trailers carts?
WRITEN in one of the brochures it says..."Save yourself some back-straining effort, and carry the heavy things in an International #1 trailer, hitched to your Cadet"... Also in the two operators manuals I have, one being for the #2 trailer, there is no mention of a "cart"...
What gives? Just one of the thousand or so things that bug me not knowing why something is called something it's not...
Maybe the "king of carts" has the answer.

Sorry Mike for jumping in, but had to know...
