510racer 0 #1 Posted July 1, 2013 My father-in-law gave me a 1988 310-8 garden tractor. However, he can't find the belt for the mower deck. The deck measures 42" (I think) - but I can't find a model number or it's been painted over. Also, the cover for the front idler pulley is missing. Can someone help me with the proper belt and how to route it? All help is appreciated very much. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,031 #2 Posted July 1, 2013 Mower decks are sized by their width of cut - not the width of the deck. If it has 2 blades it is a 37" side discharge 3 blades used on 36" rear and side discharge 3 blades used on 42" rear and side discharge 3 blades used on 48" side discharge Garry Share this post Link to post Share on other sites

bowtieguy 334 #4 Posted July 2, 2013 From the brief info that you provided your 1988 deck "might be" a 05-42SK01...spindle belt would be 106516 & mower drive belt would be 114718. 106516 belt is HA X 83" 114718 belt is HA X 45.13" HA = agricultural belt 1/2" by 5/16" I'm sure you will find this info in the files or Wheel Horse Usage Chart ..Form # 492-0392...a 94 page chart worth its weight in paper!!

510racer 0 #5 Posted July 2, 2013 Please excuse my ignorance but which belt goes from the PTO pulley to the deck? Where can I find a routing diagram or picture of its placement? Thanks! Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,031 #6 Posted July 2, 2013 I used 1986-88 42" side discharge mower deck model number 05-42MS05 The pto to deck belt is called the drive belt. The belt on the deck is called the spindle belt. Drive belt Toro 102742 nla Use 94-2501 {HA/Ax103"} 6378 Gates 1/2"x103-1/4" 40 degrees 6378 Napa 1/2"x103-1/4" 40 degrees Spindle belt Toro 6738 {HA/4Lx86"} 6886 Gates 1/2"x86" 4L860W Napa 1/2"x86" Best to get an original Toro belt if you can.
