Finally got a hold of my friend that has the commercial mower service. He says in our area, the only two commercial brands that have close service and repair are Dixie Chopper and Bob-Cat.
He has a used Fast Cat 48" which is a little larger than I wanted, but I think will work. It has 800 hours in it and he says he doesn't need it because it is too small for his contracts. He wants to sell it and get a bigger one to replace it. Asking $2500.
I looked up online and don't know if this is a Fast Cat Pro or a Fast Cat RZ. I will have to ask. It has the Kawasaki motor.
