Just bought a used Scag Cheetah with the 61" Velocity plus deck and the 31 Kawasaki engine for $6800. Has 50 hours on it and looks like new when you wipe off the dust. I was really wanting a Tiger Cat but this popped up and seemed to me like too good of deal to pass up. Was it? Also where can I get the manual for one? Will Scag send me one for free? What weight engine oil for that engine?
