I thought that 17 was skimpy for a 44". That is only .38 horsepower per inch of cut. In looking at different mower models, about .45 horsepower per inch seems to be the norm with commercial mowers. My Bad Boy having the smallest available deck gives .54 hp/inch. The extra power is pretty handy cutting Bahia grass.
I just got the Bad Boy and only have 8 hours on it. Just did the breakin oil change. Other than the control levers being a little extra sensitive I think it's a fabulous machine. The thing is so blasted fast that along with the sensitive controls, it would not be a good ZTR to learn on, but it really offers high production, a quality cut and is built super tough. It will take time, of course, to see how it holds up and works out for the long term, but I have a good feeling about it.
