mtd49 0 #1 Posted December 2, 2013 I have a 520H 1988 & bought what I think is a 42" I think because on the tag are 2 numbers. Top # 6" 41 1/2. So a 42" blade. Second set on tag reads 1014567. This tag is hard to read but I think was able to read it correctly. Any ideas? Share this post Link to post Share on other sites
mtd49 0 #2 Posted December 2, 2013 (edited) Update his blade is a 6-4111. The 1014567has to be a serial #. The metal plate is hard to make out. Also read some talk about 520H motor ID plates. My 1988 31-20oe01 is a sticker type. The fuel line has rubbed the print off and I use specs from here for filters etc. Thanks Edited December 2, 2013 by mtd49 Share this post Link to post Share on other sites
