I own all three, Turbo Force, Ultra Cut, and Velocity and I can tell you from experience the Turbo Force shares absolutely no wet discharge traits of the Velocity. It starts throwing huge clumps at the mere mention of moisture. I do cut large expanses of tall fescue and yes, I would agree with you that the Velocity is superior to the Exmark and Toro for my application. As for maintenance and repairs, I shouldn't have to deal with that for much longer as I am weeding out the Exmark and Toro ZTR's. All of my walk behinds are Exmark and I do believe they are still the best in that area.
