Shynon 7,435 #1 Posted May 22, 2017 I just picked up a sickle mower. Model #7 1311. Somebody made the underbelly drive. One thing I did notice is the frame mount on the transmission end is much narrower than my sms425. If that is correct what tractor would it fit or did the P.O. also make that? otherwise it looks in pretty good shape. 6 Share this post Link to post Share on other sites
WHX?? 46,797 #2 Posted July 24, 2017 Now I see why you need the mule drive! Did you ever figure out why the rear attachment is narrower? I notice the part nos are different from a SMS-425 and a 7-1311. 1 Share this post Link to post Share on other sites
