Don't take this wrong way dude, but you seriously need to read the posts that people send to your questions.

You've asked this belt question a number of times, in different forums, and 4 or 5 pages of posts has resulted, and still you don't know the belt you need?

Let me sum it up for you...(I am quoting harleysportster from an earlier post)

<<<<There are 2 Dayco belts that will work. The 1080 is slightly smaller than the original JD M66345 but works for some, but others are using the 1078. They both show up in different vendors books.

Here are the belt measurements:

M66345: 47.3 inch (+- .12) x 1 1/4 inch
1080: 46-3/16 inch x 1-1/4 inch (3/16 =.018)
1078: 46-5/8 inch x 1- 1/4 (5/8=.625)

The belt measurements are nominal which means close but not actual>>>>

Hope that helps, and hope you get the correct belt for many miles on the snow.
