Ive been planning on purchasing a commercial grade ZTR to replace my compact tractor. I'm leaning towards the ferris 700/1500 or 2000. The suspension is what sold me, as the 1.5 acre property has seen 30 New England winters since it was last graded, and was never really fine graded to begin with. I test drove a 2011 IS2000, and it was the smoothest running zturn i ever tested. I'm considering between buying a 61" big block vanguard IS700 or spending an extra $1000 for the 52" Kawasaki IS2000. My question is how does the ride compare between the 2000 and the 700/1500? I know the suspension is different between the two, but is the extra grand worth it in this application? Can I get 15-20 years out of the 700/1500?
