cumminscook 60 #1 Posted February 19, 2014 Hey guys I picked up a sickle mower at the big show last year and I want to get it ready for the summer it just needs the belts the only number I found on it is A-75311 I was just wondering if it is the same as the 7-1311 I looked in the manuals on here and could not find mine thanks Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,026 #2 Posted February 19, 2014 A-75311 looks like a 1964 serial number so perhaps you have this one 50in cutting width? Garry Share this post Link to post Share on other sites
cumminscook 60 #4 Posted February 20, 2014 If it is a SMS-50 will work on my 1257 or 312? Share this post Link to post Share on other sites
AMC RULES 37,125 #5 Posted February 20, 2014 I don't know about your 312... but it should mount up to that 1257 with no problem. Share this post Link to post Share on other sites
evanloock 221 #6 Posted February 20, 2014 (edited) A SMS-50 is for a wide frame tractor such as a 953, 1054, 1054-A or GT-14, not a long frame tractor such as a 1257. Hopefully you have one of the 50 inch mowers for a long frame tractor. Post pics of the mower. Edited February 20, 2014 by evanloock 1 Share this post Link to post Share on other sites
AMC RULES 37,125 #7 Posted February 20, 2014 Wonder, is frame width the difference between a SML and a SMS-50" mower? 1 Share this post Link to post Share on other sites
evanloock 221 #8 Posted February 20, 2014 Yes and the SMS-50 and SMS-505 have a different mounting plate and lift assy. than that used on the long frame tractors. 2 Share this post Link to post Share on other sites

refracman 167 #12 Posted February 23, 2014 your pics do not show the main frame mount with the correct angle. the diff between the 953/1054/gt14 and the 1257 is the the main frame mount. The 953 style has a 1" off set and the 1257 style both side are straight and the attachmatic mount is wider also for the 953 style 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,026 #13 Posted February 23, 2014 Something I find odd is there is no sickle bar listed for the GT-14 anywhere. Garry Share this post Link to post Share on other sites
Lane Ranger 10,943 #14 Posted February 23, 2014 (edited) Here is our SMS-50 Sickle Bar Mower on our 1965 -1054-A tractor. [ These parts are from a 50 inch sickle bar mower but this is a Model 7-1312 . The U Shaped piece on the end of the bar is where you bolt up the sickle bar on the back of the tractor -in front of the transmission. The SMS-50 does not have this type of "bolt up" and instead has a plate that bots to the back side of the tractor (or front of the transmission actually).

Lane Ranger 10,943 #18 Posted February 24, 2014 I always learn a thing or two from each of these implement postings! I did not know that the 50 inch sickle bar mowers had two different sized frame plate mounts! Here are a couple photos of the 50 inch sickle bar mower frame (7-1312) that I noted above. Just like Evanloock indicates above their are two different sized 50 inch sickle bar main frame setups. The SMS -50 is wider and the 7-1312 is more narrow for different applications. The large main frame rests outside the frame of the tractor and two nuts and bolts on each side hold it in place. The second photo shows the rear bar that rides between two bolts in front of the transmission where the angled pieces come off the frame of the tractor in front. 1 Share this post Link to post Share on other sites
