AJ Desalvo 27 #1 Posted May 15 Hello Folks! I just picked this 310 up with the hopes of getting it in good shape for my mother’s yard. The model/serial number tag is not legible. Any suggestions on how to identify the approximate model year? Thanks in advance…. 2 3 Share this post Link to post Share on other sites
OutdoorEnvy 1,761 #2 Posted May 15 Nice rig! That's a great model. Based on the decal color it's 85-89 I think. If it's a K series engine it's either an 85-86, if it's the Magnum Kohler it's 87-89 I believe. Very capable model though that should be a great worker. 1 1 Share this post Link to post Share on other sites

pfrederi 18,520 #5 Posted May 16 WH used same spec number engine for several years 1988-1991 If the serial number is readable on the engine might narrow it a bit. Very little in changes during the 88-91period so not really an issue when you need parts. 1 Share this post Link to post Share on other sites
