Mushrush 16 #1 Posted April 28, 2023 Maybe I'm not skilled in the art of searching the internet, but I can't find the size belts for my mower deck. I don't know if I need them yet, but I would like to have some in stock in case I do. I was mowing and all this white smoke came out of the mower deck. I looked underneath and only my middle blade was spinning. I'll be pulling the deck this weekend and do my assessment then. But since the tractor is still new to me, I might as well put ew parts in it Any help would be greatly appreciated. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,026 #2 Posted April 28, 2023 36" rear discharge? This may not be the model of deck you have but the belts will be the same. The 312-8 is a long frame tractor. Click on the fuzzy picture 1 Share this post Link to post Share on other sites

I just had the same problem with my 48" SD deck. Edited April 28, 2023 by Ed Kennell 2 Share this post Link to post Share on other sites

peter lena 8,576 #6 Posted April 29, 2023 @Mushrush cut with a 36" R/D for years , how easily does that spin up ? clutch screaming ? do you feed in the pto lever slowly or just slam it on ? when the deck runs what does it sound like ? underside packed with grass? mower decks are a collective drag on the drive set up , if you can send some pictures , pete Share this post Link to post Share on other sites
Mushrush 16 #7 Posted April 29, 2023 (edited) I was just asking for the belt size. I'll figure out why only one blade is spinning. But there's a drive belt,(PTO to deck) and the deck belts/belt. (Drives the 3 blades) I was asking the size and/or part number for the deck belt (or belts) Edited April 29, 2023 by Mushrush Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,026 #8 Posted April 29, 2023 Go back up and click on the fuzzy picture in the link provided. The page that opens has the belt numbers and sizes on it. The reason they have been added to this page is some charts are not correct and no way to change them. And they are not all done yet. Share this post Link to post Share on other sites
clueless 2,974 #9 Posted May 2, 2023 (edited) A couple of things would help us help you. What tractor do you have and is the deck the original? The 36" deck came in at least 3 configuration and three different drive system since the mid '60s. "A picture saves a thousand words", and a lot less posts.
