wx,
Just to explain why I recommend the 200CX: putting the loader on the 2210/2305 completely changes the weight distribution and balance of the tractor. You will want to pay careful attention to the ballast needs . . . and by the way, the tractor WILL lift 815 lbs. In fact, these numbers are from the 210 loader, but the 200CX which also goes on the 2320 and the 2520 is almost identical: 750 lbs to full lift height (68"), 800 lbs to 61", 850 lbs to 51", 900 lbs to 45" 950 lbs to 38" and 1170 lbs to 16". Anyway, because the distribution and balance are changed, you will not want to mow with the loader on. If you go with the X, you will be forced to do so or invite all your buddies to pick up and take a 547 lb loader off each time you want to change. For just a few hundred dollars more, go with the CX and the 53" bucket, and get the quick hitch advantage the tractor was designed to have, and the item that purchasers will want if you decide to sell the tractor.
On another note, what mower deck are you considering? I hope the 62C. There is a premium again, but it is well worth it, for resale, for better overlap over the tires while mowing (the 54 barely covers the tire tracks), for better maneuverability (the uncut circle of the 62C is 36"), and effectively moves the ROPS (IMHO the largest factor in maneuverability) effectively away from your trees etc.
Happy hunting!
