I never worked over 200 acres at a time, in pieces, over the years so I never had the need for batwings....no comment there.
On others, I had several brands and never had a bad brand; each did their job and my pockets weren't deep. What I did find was that for the Houston Black Clay soil around here that is prone to establishing "sink holes" in slow rolling hills with numerous terraces to keep erosion under control, scalping has been the biggest problem in determining what mower to use.
That puts me in the narrower than I would like category but so be it. Only time I destroyed one was accidentally on top of one of those terraces with a Mohawk 8' twin blade, dual wheel, got high centered. Ripped the center gear box out running the 100 PTO JD on it before I could get it shut down and the slip clutch didn't protect me. So much for slip clutches on that, prefer shear bolts and yes I know how they are supposed to be adjusted and maintained.
