TC10284 110 #1 Posted August 8, 2023 I have a 37" Side discharge deck for 200 series (211-3). Is there a way to adjust the belt tensioner? Currently it doesn't move much. I tried loosening the bolt under the drive pulley but it wouldn't budge. Not sure if I should keep trying since it has a spring on it.

Pullstart 59,835 #2 Posted August 8, 2023 I don’t know a ton about that model, but it looks like the tensioner has a coil spring under it? Have you tried to take it apart, clean and lube it well? 1 Share this post Link to post Share on other sites

peter lena 8,095 #4 Posted August 8, 2023 @TC10284 that deck is common to the rear bagger set up , pretty complicated for its size / function . agree with others on having an overall look . the newer idler pulley , showes intent , would look over EVERY ROTATIONAL FUNCTION POINT , they are saposed to hand off belt drive rotation to the next pulley , wich is usually bound up or rough in operation . would turn it over , verify what you have for movement , grass build up restriction , that belt tensioner is probably struggiling against rust / build up , pulley issues . bet related parts are rust , grass bound in place . expect numerious related issues , sold one of those months ago , for parts ,pete Share this post Link to post Share on other sites

I could try an impact, but wasn't sure if I should. 1 Share this post Link to post Share on other sites

I put it on because it was missing. Original owner was probably having same issue I had of tensioner not working? Share this post Link to post Share on other sites

TC10284 110 #8 Posted August 13, 2023 After removing the shoulder bolt from the spring tensioner, I have found that it is bent and need to be replaced. Although it looks like Toro 108176 is discontinued. Anyone know of a replacement? Share this post Link to post Share on other sites
TC10284 110 #9 Posted August 18, 2023 Just wanted to follow up on this to see if anyone knew of a replacement shoulder bolt. Share this post Link to post Share on other sites
oliver2-44 8,875 #10 Posted August 18, 2023 Try you local hardware store with all those grey drawers. I just saw shoulder bolts in them at my Ace while looking for other parts. Google it, Amazon might even have some. 1 Share this post Link to post Share on other sites
TC10284 110 #11 Posted August 18, 2023 I went to Lowe's, Tractor Supply, and a local Ace True Value Hardware store. None of them had what I needed, but the True Value store had a bolt, a bushing, and two washers that would have worked perfect, but the bushing was just ever so slightly too big. So I got to looking in my spare bots/nuts/washers bin and found everything I needed. The bushing was plastic and slightly too small, but I decided to try it anyway. Put some white lithium grease in it, then bolted it on. So far it is working well. The plastic bushing may not hold up long, but at least I know a way to get around needing this P/N. I think I'm going to need another one anyway, because I have another 200 series 37" SD deck that I don't think the tensioner is working. Share this post Link to post Share on other sites
