They are bringing me a Exmark with the new updated 66" Triton deck and a 31 hp Vanguard. They are also bringing me on the same trailer a Scag Turf Tiger with a 61" Velocity Plus deck and the 35 hp Vanguard. My understanding is the 35 Vanguard is a horse but it really likes fuel. When I finish I will know all and any differences between the Hustler Super Z 66" XR-7, Scag Turf Tiger 61" Velocity Plus, Exmark 66" Triton and the Bad Boy Lightening. This should be very interesting ! ! !
