I have a Ferris dealer and Ariens dealer in town...I am a homeowner that has 2 acres to mow - I am looking at a Ferris IS 1500 ZTR 21hp/48" deck and also considering a Ariens HVZ 2350 which is a homeowner grade ZTR - Ferris is priced at about $6000, the Ariens is 23 hp and 50 " deck for about $3300. Is the additional quality of a the commercial grade Ferris worth the difference in money in the long run. I get different stories from different people. I tend to want to buy quality but I also don't want to overdo things for my needs either. Any advice is appreciated! From searching the forums the Ferris has excellent reviews. I have not seen many postings on the Ariens though I've heard good things about Ariens/Gravely.
