I have both here side by side. Both trades, I agree with the guy earlier the Fastrak looks a little beefier. I like the Scag with the motor turned the right way instead of to the side, and I like the bars on the rearend of the scag protecting the motor. Here is my negative on the scag. I don't know if its a weird coincedence or what, but the one Bad Boy I sold with a 19hp Kawasaki for a homeowner in 2008 crapped out last week (just installed a new one on it for $1550), and on a Scag 48" 19hp I got on trade couple weeks ago is smoking like i am spraying mosquitos. I just got rebuild parts to rebuild both the old BB motor and the scag. This is the only 2 kawasaki 19hp I have ever touched, sold ,or seen in 5 years I have been a mower dealer, and they both require rebuild same week. Both motors were built in 2008 and both were homeowner owned very well taken care of. I personally would lean someone on a machine with the 23 or 25hp more streamline kawa here with much less issues. Percentage wise the 19hp has a 100% failure rate here within 300 hours on one, and 1200 hours on the other...lol. The Scag does a have bigger discharge chute opening, but they cut so identacle its scary.... no wet lush grass to compare though.
