I really can't add anything to this thread given that I don't know much if anything about the Bush Hog or Woods models, and although I've been pleased with the Land Pride RCR1884 behind my MX6000 my experience is very limited. In a perfect world we'd get to demo these models under a variety of conditions and pick the best one for us but that's not how it works unless you have a large following on YouTube!
I'm surprised at the cost you were quoted for the 1872 which is a lot less than the 1884 I bought ... a lot less. Does that include front and rear chain guards? I doubt you'll be disappointed with whichever model you choose unless it doesn't do a good job of cutting, or breaks all the time, or has some other quirk. Removing and installing the blades is a pain but I'm sure that it's a pain regardless of the model. I bought a spare set of blades last week so that I can have a sharp set on hand if needed.
