Wow, I can't believe I missed this thread. My 1100 came with a Continental-Belton MMM that runs off the rear PTO. While the mower itself seems very good (and their customer service was excellent, they sent me an owner's manual right away, free)...as jbrumberg points out, it eats up way too much ground clearance. With the belly mower mounted, I've got less than 2 inches of ground clearance with the mower fully raised. Now, i'm not mowing pasture, but my yard's not a golf course, either, so this lack of ground clearance is a real problem. I took the mower off (which is a minor hassle in itself) and eventually I'm going to make it into a rear mounted mower...
