I spent three weeks agonizing between the BX and the 7500. These are the issues that swayed me to the 7500 as I was pretty sure that they would both handle what I wanted to do at the moment.
1. I opted for the extra hydro volume as I was not sure I wouldn't want to run something in the future that the BX wouldn't handle as well.
2. I liked the extra ground clearance though they both seem to be the same with the mower installed and in the upright position.
3. Kubota seemed to have to go some to make it all fit in the BX. ie engine in backward, gas tank under the seat, which I thought could make some maintenance more difficult.
4. My main reason was that since they put the gas tank under the seat when you adjusted the seat back it would also get higher. I needed it all the way back and it felt like I was reaching down to the steering wheel. I was worried that this would become tiring after a lot of hours on the machine.
5. Lastly are the little really meaningless things...tachometer, forward opening hood altough I have to put the lack of a cup holder squarely on the BX side plus I think the BX with its garden tractor feel would have made my wife feel more at home. The clutch adds another dimension to operating the 7500.
Also, I'm pretty sure I heard a back hoe was in the works for the BX. Does anyone else remember hearing this? I do remember that when I walked into the dealership my initial feeling was that the 7500 was just right sizewise for what I needed and after using it I was right. The only real thing that kept me coming back to the BX was the price (my wife) who gradually saw things my way (bribe). I also figured that this would probably be the last tractor I would buy and that I might as well get what I wanted. I guess that would also go for opting up to the 30 hp if thats what your gut tells you. Better too much than not enough.
