gwest_ca-(File Mod) 11,036 #2 Posted August 8, 2022 The parts list is shared with more than one size of deck so multiple belts listed. An original ipl which we do not have will answer the question or click on the fuzzy picture in this link. The belts are listed on the page that comes up.

gwest_ca-(File Mod) 11,036 #3 Posted August 8, 2022 Sounds like the pto clutch may be slipping. Tighten the trunnion on the pto rod about 2 turns and try again. 1 Share this post Link to post Share on other sites
daveoman1966 3,745 #4 Posted August 9, 2022 Schematics show the deck belt to be OEM # 1594. If the idler pulley is bad, OEM 112425 (or 92-7101, 6719) is the replacement and I have a NEW one on Ebay... item #134146422225. If you purchase this pulley from me on eBay...I'll include a good used Spindle belt #1594 for your 48" deck. 1 Share this post Link to post Share on other sites
