I have ~2.5 acres to mow. A few trees, but mostly flat and open. I currently have an old 20hp 46in MTD lawn tractor, and on a good day I can get it all cut in ~3hrs (not counting weed-eating, etc). I would like to get that time down to ~1.5 hours. I've been reading the forums and looking at local dealers and believe a ZTR mower would be my best bet for cutting down on time. I've read all the wonderful things about Hustler MFTs, and having seen one in person I can believe it. The problem I'm concerned with is that I really can't afford to go bigger than the 42" in a Hustler (~$4,000). For about the same money, I could get a 48" JD, a 44" Snapper, or 44-50" Gravely. I know, from both seeing them and reading here, that the quality is not quite as good as the Hustler, but they appear adequate for what I need, and I think with care I could get 10 years of use out of any of them. My biggest concern is cutting the time it takes to mow for $4k-ish. So right now I guess my main question is boiling down to will the 42" MFT be able to get my cutting time down to 1.5-2 hrs, or should I take a little hit in build quality to get a larger deck? I know in reality there is no way to answer that without trying it (haven't asked if I could try it at home, but the dealer is around 40 minutes away, so I doubt it), but if anyone has any experience cutting a similar size/type yard with a 42" vs something a bit bigger I love to hear about it.
