Pete Steele 0 #4 Posted May 15, 2013 I have a 1257. It has a deck just like this. My deck is a 42". I need to know the drive belt size and which pully in the center it goes on. Upper or lower... Pete Share this post Link to post Share on other sites
Pete Steele 0 #5 Posted May 15, 2013 This is Pete again. They only make the 1257 in 1967. My deck does NOT use the Mule drive. This is why I am having trouble finding a drive belt or even the length. Pete Share this post Link to post Share on other sites
