Great choice on the Gravely ZT-XL 42". I have the 2022 model.
I was originally looking at the Ariens Ikon, but then I found out that the Gravely ZT-XL has better transaxles (ZT-2800) that are serviceable with replaceable filters for a bit more, so that's basically what made my decision.
I did a lot of research, and unless one got under my radar, there's not another make/model of zero turn mower that offers the ZT-2800 hydros (the lowest-spec model transaxle made by Hydro-Gear at that time that still had serviceable hydros with replaceable filters) at that price point (around 5 grand). Of course, my other requirement was a mower that would fit through the 4' gate of our back yard.
Also liked that the Gravely 42" has 3 blades, compared with only 2 blades of some other OEMs with this size deck.
I think Gravely, compared with many other zero-turn OEMs (I heard there are 36 manufacturers of zero-turn mowers or something like that), offers a lot of value, often including higher spec transaxles on given models than other OEMs.
I've been really happy with mine, with over 20 hrs on it so far. Of course, having bought it in September, I didn't do a lot of grass mowing with it last year, but I did do a lot of leaf mulching, since we have lots of trees in the front and side yards (I had the dealer install a mulching kit before I picked it up). It did a great job with the leaf mulching, and it also mulches the grass clippings very well. I haven't tried side-discharge and have no plans to, since the mulching kit works so well.
Looks like yours has some updates (frame, updated deck with removable servicing plate on top for easy access to pulleys, which I wish mine had, new frame, new LED headlights, better seat with vibration isolators, more aggressive tires, updated styling).
Can't tell, but did they change the deck height adjustment mechanism on yours? Does it have the knob (like mine), or the pin-and-hole setup, a-la ZT-HD? Personally I wish mine had the latter style.
Have you run it yet?
Let's see some photos!
