Long story short.... I've been hashing the two tractors over far toooo long /forums/images/graemlins/smile.gif . One of the things that bothered me on the 2305 was the lighter rated axles. According to the JD site, the 2305 axle specs are rated at approx 1/2 the capacity of the 2210. Sooo, I picked up the phone today and talked with a JD rep. After finally convincing them that the new specs didn't make sense when comparing to the 2305's predecessor... They cross referenced part #'s as I originally asked them to do. And.... part #'s are identical on the 2 tractors as I hoped & suspected. I'm not sure why they would change the axle ratings but apparently that is what they've done. Maybe to make the larger tractors appear to be that much heavier duty for potential buyes???? Don't know. However it's somewhat of a relief to find that they didn't lighted up the axles. Outwardly the tractors look similar... but you never know what's inside. I may check back with another rep to confirm this... Thought this was interesting info to share...
