What is "small acreage"? I have 7 and NX is way overkill for 99% of what I need a tractor for. I needed as close to 8' dump clearance on loader bucket as I could get so that unusual requirement on my shopping list put me in much larger frame sizes than I need for general tasks. CK3510HST with just the telescoping 3pt upgrades would be more than enough. I don't regret having the mass, power, stronger loader, better traction, more comfortable ride, all the NX extras (most of which go unused), but none are necessary most of the time.
Depending what "small acreage" means to you....an NX with loader and a 6' bush hog is a good 21' long so that's something to consider if mowing will be a task and there are lots of obstacles or tight spaces. Turns pretty tight for it's size, but still have several areas I'm spending lots of time doing little K turns or making a complete circle to catch one little strip. Still faster overall than my little tractor with 5' bush hog, but wasn't the dramatic difference in time I expected due to the additional time navigating tight spaces. A CK3510 with loader and 5' bush hog is probably closer to 17' overall length - 4' difference nothing in a wide open field, kind of a big deal going around sheds, gardens, landscaping, odd shaped parcel mowing patterns....just one more consideration to muddy it up for you
