I have an opportunity to purchase a 2010 IS1500Z for $5900. It's not a demo or anything, just an end of season special. I'm told normal retail is $6499 or so. It is a 48" deck so the ICD cutting system is not available (only available on 52" and greater. The dealer is telling me it is a 20 HP Kawasaki, but the website says 21. The dealer claims the website is wrong. So not sure on that Will I regret not getting the 52" ICD deck? (that model is regular price at $6899 iirc). The 48 does appeal to me because I do have a lot of tight spots to get into. The dealer was sort of wishy washy with his opinion on the ICD deck -vs- the standard. Will I be happy with this mower? Is the 20 Horse enough? Thanks everyone, I welcome any feedback, positive or negative.
