The generic term for a rotary mower designed for rough cutting (aka brushhog) also seems to vary regionally. I believe the Texans call them shredders which is a pretty accurate description. We call them brushhogs in New England. I don't know which came first, the BushHog or brushhog. However, to get back to the topic of this thread, I run a 48" Bush Hog SQ480 "Squealer" on my CK20 and it does a fine job both as a cutter and as ballast.
