gwest_ca-(File Mod) 10,444 #2 Posted April 3, 2018 Welcome to the forum. Have a model number and serial number on the deck? Is there a drive belt with the deck and is it a 4-sided belt or a 6-sided belt? Garry Share this post Link to post Share on other sites
Justin compton 0 #3 Posted April 3, 2018 Can't really make out the numbers but it's one belt from deck to pto clutch... Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,444 #4 Posted April 3, 2018 It makes a difference to the idler assembly you inquired about depending on how many sides the belt has. 4 or 6? If it is 4-sided half the idlers are flat and if 6-sided they are all v-idlers. 37" side discharge deck. Click on the pictures Garry 2 Share this post Link to post Share on other sites
Justin compton 0 #5 Posted April 3, 2018 It's the side discharge deck...so I'm guessing it's the 6 sided? Share this post Link to post Share on other sites

They are both side discharge, don't be guessing, you need to know if the deck uses the 6 sided or the 4 sided before you proceed. Share this post Link to post Share on other sites

gwest_ca-(File Mod) 10,444 #8 Posted April 3, 2018 Suspect your deck is a 1987 model year. The model number is 05-37SC01. Click on the pictures Now look at the idler pulleys inside the deck. If they are both for V-belts you need the idler assembly that has 2 v-pulleys as illustrated in the parts list. Reason for mentioning this is many decks have had their idlers replaced so they match the later 4-sided belt design. You don't want to be purchasing the wrong ones. This is a good service bulletin to print out and have with you when installing the six sided belt. Do it wrong and you will be needing another belt.
