4” pulley. I’m assuming factory diameter. Can’t find proper belt size. Admittedly haven’t looked real either. 1/2”X30”ish sound about right? Also looking for a reason to post. Thanks

QA-42A blower belt size

Help Support IH Cub Cadet Forum:
I think the belt you need is 15/32x28. But if you click on the link to cc specialties at the top of this page(they are a sponsor to this forum and help make this community possible), then click on site navigation, and then click on belts. Then finally scroll through his page to find your belt. You'll also have to look at the pto clutch to make sure it's standard size. If someone before you put an aftermarket pto on, it may be a non standard size pulley, which will affect belt length.
Actually, I would advise clicking on all the sponsors pages. I guarantee each one of them will have something you'll put on your wish list.
No way to tell you what size the belt is without knowing what tractor it's going on.4” pulley. I’m assuming factory diameter. Can’t find proper belt size. Admittedly haven’t looked real either. 1/2”X30”ish sound about right? Also looking for a reason to post. Thanks

That does make sense. I thought it was an attachment question. It’s on a 1976, 1450. Thanks for the heads up.
I have a 1975 1250 with the QA42A blower, stock driven pulley. I use a L433 48 X 330 belt that works perfectly.

I think I figured out the painfully obvious! 
I have the “42A”, not the “42”. 15/32”X30”. Does this seem accurate to the knowledgeable ones? My tractor is also a ‘77. I’ll guess so is my mower deck. Was this a popular combo package from the dealer? It seems like the standard package being sold these days. I’m new here and something I picked up on. Thanks again!
