If you had a flat yard and only mowed, a X350 would be fine. If you had a sore shoulder or wanted to run a snowblower (higher lift and steering efforts), a X370 with PS/PL would be wonderful. Add in hills and want to pull loads or push snow: think X380. Maybe find a used one?
Leveling a deck is one of the most important things to do to optimize cut quality. My dad and FIL said the same thing as you though. ;<) They found it wasn't complicated once I went through it with them. It also calibrates the deck to the deck height knob: you set 3" height-of-cut you get 3" HOC! Make the dealer show you how it's done.... several times! I do it once a year when I prepare the machine in the Spring. Hope this helps! Randy
Thanks for the info. It would only be used for mowing, I have a tractor and an ATV to plow snow or do heavier duty tasks.
Yes, I did have the dealer show me the height adjustment...there was a pedal, a knob and some sort of lever on the dash (which he didn't really explain very well). I suppose like walking and chewing gum, once you get used to it adjustment on the fly would probably become second nature.
Curiously, does all this leveling mechanism make it more difficult/non-intuitive when removing the deck for cleaning/sharpening/belt replacement?
Avoid the Husqvarna, it doesn't really have a frame.
I didn't know that. I'll have to look into that more. The Husq sellers around here are hardware stores, TSC, etc., not an actual dealer, so finding someone there who knows the product isn't likely.
What ever you get in your rocky and hilly areas, get something with a Limited Slip Differential, or a Differential Lock. I like my Cub Cadet, XT2 LX42, ... I would like it much better, with a manual locking diff.

Just say'en......
That would be a nice to have. Turf tires don't have much traction if the grass is even slightly wet. Tried loading them on a previous mower, but it didn't help much.
All good info here, appreciate it. Fortunately, my current one is still more or less running so I can take my time shopping. Any online reviews/ratings I've seen have been all over the place, or posted by someone less than objective (ie-someone who deals on one particular brand).
