ebinmaine 63,533 #1 Posted April 9 This question is primarily about a late seventies c121 Hydro 36-in RD deck Drive belt. Looks to me like it's supposed to be a standard rubber type 1/2 in wide 96.5 or 96.7 inches in length. Is there an aftermarket belt other than the Gates Blade Runner that I can use? Will a normal average everyday ½ by 97 drive this okay? Are these the same belts used on Long frame tractors for other sizes of mower decks as well? 2 Share this post Link to post Share on other sites
squonk 39,144 #2 Posted April 9 If your deck has the std sliding idler deck pulley like a 42" RD deck has I don't see why you can't run a Tractor Supply 1/2 X 97 belt on it. I run a TSC on mine and I believe it's 97" 2 1 Share this post Link to post Share on other sites

elcamino/wheelhorse 9,117 #15 Posted April 10 I think they use the same belt. Only have one SD and it is set up for leaves. 1 Share this post Link to post Share on other sites
peter lena 8,133 #16 Posted April 10 @ebinmaine as you are aware , the belt deck " bounce " is a result of incremental , bearing hang up , the more it bounces , the more rotational / bearing issues are evident . have detailed my flat idler pulley , like a larger bearing , bush the inner to 3/8 same bolt fit . also have added a flat idler ,on the back unsupported area , about middle of long run , drill a hole , 3/8 bolt , elastic lock nut. have that on 3 decks . no belt buzzes, Pete 1 Share this post Link to post Share on other sites
aemsee 93 #17 Posted April 14 (edited) I measured the external length of the deck belt for my 36" RD mower. It is 77". ?? 97" just seemed incredibly long for my deck. Edited April 14 by aemsee 1 Share this post Link to post Share on other sites
