Lots of good tractors in that range and almost all would be fine for use in a small vegetable patch. With just 1-2 acres I'd go for the 20ish HP myself as those tractors have slightly smaller frames which could be handy. 4 foot implements would be reasonable and are both cheaper and easier to store than five or six foot implements used on bigger machines. Kubota B series is very popular though the B7800 is no longer made and is perhaps a tad big for what you are doing. There are B series under 30hp too. JD and NH make nice tractors in that range as do Kioti, Bobcat (rebadged Kioti), Mahindra, TYM and MF too. Stay away from the subcompacts if you value ground clearance and ability to use Cat 1 implements but there are certainly people who do a fine job in small gardens with subcompacts too. You'll need to decide if you want an HST transmission which will cull the list a bit. You should also just visit your local tractor dealers regardless of the color of the machines on their lot. Big bonus points for a good dealership.
The Kioti CK27 and CK30 have 13.8" of ground clearance. The CK30 also has a higher front end loader lift capacity (1155lbs vs. 1065lbs) then the Kubota B3200 and higher lift height (92.5" vs. 82.6"). Also, since you are cultivating I assume you are looking at good rear PTO HP as well, the CK30HST has 30 engine HP and 22 PTO HP while the B3200 has 32 engine HP and 23 PTO HP. Close enough to hardly notice the difference.
For ground engaging work, you really want the weight of a heavier and more solid tractor. The CK30HST is 3,142lbs vs 1,764lbs for the B3200, you can add weight but how will a 1,764lb tractor perform with an extra 1,400lbs on it...
Also if you're not afraid of older tractors, check out Farmall Culti-vision tractors...A, Super A, 100, 130, 140. They're among the best cultivating tractors around, and relatively economical.

I agree with Soundguy. If you are just into gardening 2 acres. An antigue row crop trike will outperform a modern CUT for a whole lot less money. I have a Case VAC 1952 trike with lots of ground clearance,narrow ag tires, and variable rear wheel width. Perfect for small plot plowing,cultivating,tight turns.
Here's my 1951 Farmall Super A, a real truck garden tractor. The bull gear setup on the rear axle gives a 20" ground clearance when all the support brackets for the pto are removed. I bought this one last year for $1300 including a mid-mount sickle bar mower and a 3-pt hitch. There are quite a few of these still around and parts are easy to find.
