Re: New member- loooking for first JD
Even though they all look like tractors, the key thing to understand is the difference between a "riding lawn mower" and a "lawn and garden tractor". The least-expensive models are riding mowers, and the higher models are lawn and garden tractors. The big distinction is the transmission. Riding mowers have a trans that's good enough for mowing on flat yards, and as you move up the price scale, the trans is stronger to make the machine more capable of mowing hills/inclines regularly, pulling stuff around, and even using ground-engaging equipment (at the top end of the spectrum).
When you're looking at new models, you want to buy as much tractor as you can for increased capability. For example, in the X300 line, the models that have power steering have a transmission that's a step up from the one in the X300's that don't have power steering, and it also gives you the ability to change the trans fluid easily. ("Easily" meaning there's a drain plug underneath, so you don't have to remove it from the tractor to do it.) And of course power steering is a very nice feature I didn't know I needed until I got it! The X330 is kind of a strange combination of some of the X300 series features but without the Kawasaki engine. For that reason, I'd start looking from the X350 up. For an acre, a bigger mowing deck will save a little time. The 48" deck has more anti-scalp wheels than the 42" deck, and that's handy not only for helping mow evenly but also when it comes time to pull the deck out of the machine for service.
There are lots of folks here who can speak to the capabilities of the tractors you've mentioned and discuss the best options on the used market. The advantage of going with used is that you'll get a more capable tractor (maybe in the range of a new X500 or better) for a lower purchase cost.
