Nice! I am sold then. How short is short to you? Obviously can't be to long. I just measured and center to center I would be between 20 and 22 inches. Id assume shorter and a tight chain is better in this case. I may be able to shave off 2 inches or so if I start cutting into stuff, but my steering box is real close aswell. Just to give you an idea my ragb will be pretty much under the front of the seat. This is so I can get the mower as low as I can. I could go closer just the gearbox would sit under the bottom of the frame instead of up and in. And I wouldn't be able to go much lower. Thanks very much by the way for your help. I appreciate it alot. You just easily saved me a couple unnecessary steps in my build
