I'm considering the Landpride RTA 1250 rototiller for my B7200. The tractor is rated for 14 PTO HP. The Landpride specs say 15-40HP. I could go with the Landpride RTA 1242 (also spec'd for 15-40HP) but it would not cover my tractor's wheel track. Anyone with advice and experience with this would be appreciated. Thanks
