I have been looking at 12' batwings for a while. Currently there are only three major players in the 12' batwing world, and nearly everyone makes single fold 10 footer. All three brands are way too light for anything more than clipping short grass. The Bush hog 2212 appears to be very close to the Rhino but is at least $2k more than the Rhino, and the Rhino comes with aircraft tires. The Landpride appears to be the lightest of the three. I have talked to Rhino and Bush Hog about making a heavier 12' batwing but appear to be no interest at the time.
One brand not on the radar is Lowery Manufacturing in Boaz, Alabama. They have started producing a medium duty cutter in both 12 and 15 foot units. I have seen the 15 foot unit up close (actually have pics) and it looks very nice for its price. I was told the 12' is the same build just smaller. Like all LMC stuff it appears to be rough cosmetically but I have several of their attachments and they are all holding up very well.
FWIW the price on their 12' batwing cutter was $6500 at the first of the year.
