The 1860 has a shorter wheelbase, I think that's why they put the little tires on it.Learn something new every day!
I had read that the BX18xx and BX2xxx tractors had the same frame size and drive line, excepting engine HP, and it never occurred to me that Kubota would put a different tire size on a tractor of the same physical size...

Huh, I didn't know that. I thought all the bx18xx were the same. Now I learned too!Amazing! Who can keep track of all the models and changes? Not me!
I see the BX1830 still had the 55.1" wheelbase, then with the BX1850 the wheelbase was shortened to 52.8".
Perhaps there were other changes introduced as well? Wonder what the motivation was...would never have expected this change.
