I have a 2010 X720 with the 54" gearbox driven belly deck and have been very happy with it mowing everything from less than 1/2 acre up to a few acres, but to be certain these X3xx, X5xx, and X7xx mowers are exactly that: mowers. If you want to put a bucket on the front you'll have to go aftermarket. If you want to put ground engagement (tiller, box blade, scarifier, etc) off the back you'll need to get the rear PTO and 3-point since these are not standard on these, and those add-ons are well north of $1k. For an acre I would not go smaller than the 54" deck but that's just me. The X7xx decks are very rugged compared to the big box mowers, and, having had (have ...) many older JD 2xx & 3xx lawn tractors as well, I agree with many posters to avoid the big box throw-away mowers that are sold today assuming it's a long term buy. Having said all this would I pay the $11k that my X720 tractor cost new? Nope, sure wouldn't, but I got mine from a private estate sale years ago for $4,500. It's been a great buy and I have worked it hard with only basic maintenance. For an acre in a more suburban setting I would think about the big box mowers and just flip it every 2-3 years before the aforementioned failures begin to happen. The big green big box mowers sell for about 40%-50% of new after a couple of years use so you could be riding a new mower every 2-3 yrs and still be doing OK financially. But if you want a front blade / bucket and/or rear ground engagement step up to the sub-compact tractors. $20k for a sub-compact buys a tractor-loader-backhoe with belly mower at any of the green, orange, and red dealers if you're OK with pushing hard on price. This year might be different because of the short supply issues so maybe a big box mower this year as a stop-gap and a TLB next year ??? Good luck!
