rww_94,
The 7500 is a nice tractor. We tried it out and it wasn't a good fit for our property. The BX does mow better but there is nothing wrong with the 7500 mower. The BX won out because it felt more stable on the hills, the shorter ROPS is much better in the orchard and nursery, and the 7500 MMM wheels would drop in the badger holes around the place.
I really wanted the 7500 but the BX was a better fit (I hate to admit /forums/images/graemlins/mad.gif). If you have the room go for the 7500, great tractor, if you have more room go for the 7800 /forums/images/graemlins/laugh.gif.
And be sure to get the FEL,
Michael
