I am considering replacing my Exmark Viking, 36" hydro. It has 17 seasons, and perhaps as many as 8,000 service hours. Engine has been replaced one time, one pump replaced, and lots of connections are getting very loose. Terrain and gates dictate the 36" so no need to encourage to buy a larger width. Under consideration are the two mowers listed above. I have seen the Snapper Pro SW30, 36". I have not laid eyes on the Ferris. I have looked at the details and pictures of both online. I am looking to confirm my understanding of these two mowers. It appears they are identical (frame, height adjust, wheels, engine, ZT3100 transaxle, deck, controls, etc.). The only difference I can see is the Ferris has an electric start on the Kaw, the Snapper Pro is pull start. My use of a w/b is part-time, about 300 hours per season. I run solo, and have a JD 48" ZTR that runs over 400 hours per season.
