Neat little mower,seat height should be fine since my huffy seat height was around 18 inches. But the only concern I have is , are you still running the 4 spd foote h pattern tranny? If you are, I would advise you to change it out to a RAGB or peerless 700. Them foote tranny's work fine in the governed classes,but wouldn't recommend for pro-x/fx class.
