paxz71usa 172 #1 Posted August 27, 2017 (edited) Can anyone tell me where to find the model/serial number of the deck on my 1973 12 automatic. If it's a paper decal it's no longer on there. If it's stamped in I've yet to find it. Lacking a model number any information you could share would be most helpful. There are no grease fittings anywhere on the deck and the 3 blades are each approximately 13-3/4" long. Thanks Gary Edited August 27, 2017 by paxz71usa Share this post Link to post Share on other sites

gwest_ca-(File Mod) 10,499 #3 Posted August 27, 2017 Sounds like a 42" width of cut deck. Here are the model numbers in the order they were produced. The deck in 1973 was model 5-1010 5-1001 replaces RL-426, 5-1421, 5-1422, 5-1423, 5-1000 5-1001 replaced by 5-1010, 5-1011, 5-1012, 65-42MS01, 65-42MS02, 75-42MS01 (Blades up to this point had a 5/8" x 3/4" double-D center hole) Garry 1 Share this post Link to post Share on other sites
