Need some opinions. Ive test drove the gravely 160 and 260. Looking to drive the 460, simplicity citation and cobalt soon. I mow over 2.25 acres and potentially in the near future anothe 3. Both are kind of rough properties. I want the smoothest ride i can find. What are your thoughts? Also the gravely has the yamaha and the citation has the briggs cobalts with the vanguard. Whats the thoughts on the motors?
