The left right brake could be done like the older Cub Cadets left brake on left side right brake on right... or combine the two... with a hydro the brake is not of the much use.
It would be more of a question... what pedals would be the handiest..
some linkage change-up hydro to a F-R rocker .... Myself I don't mind using hand lever for hydro... :smile:KennyV
