Have you looked at Mahindra? The Mahindra MAX28XL is one very nice tractor with good specs.
From all I've read the yanmar is a good tractor. Price not bad. But, you should really try many many makes and models before jumping in. They are all good, and will leave you with the feeling you got today. But, eventually one will be the obvious right choice for you. You are wise to skip the hoe.
The 2320/2520 are still not a bad choice, especially if also mowing. Did you look at the JD 3038? Kubotas are good for mowing too. Digging: Kioti, Mahindra, Bobcat. LS is also a very good value. The 1600 series massey's are awesome, but pricey.
Heavier machines are not good for mowing. Not so much about grass tear, though that is a problem too. But it's more about compaction. I had mine in my vegetable garden about 5 years back working a bank that leads down to it. Made the ground under the back tires where I was working as hard as concrete. Just now really getting it broken up good with a tiller (can't get a plow in there).
Turfs, R4s, R1s. They all have their place. The R4 is super tough and wide (stable); great for dry ground work, in the woods, and allow for maximum weight. The R1s are best in the mud (R4s no good here) and can be width adjusted. Turfs for mowing, and they are pretty good for hard surface snow removal too.
