I wrote a review but did not give star rating so I guess it didn't go through.
The 77 inch belt worked fine, haven't used it much , just tried it out. It is on a 1982 Cub Cadet 44C mower deck on a IH Red Cub Cadet 672 garden tractor.

I could not find any mower listing in catalog so just went by measurements. I also ordered and received a 5/8 th 99 inch belt that I ordered wrong. I was looked at too many different numbers and got mixed up I guess.

At any rate I am going to order a 5/8 x 89 inch belt for same mower to drive from electric clutch to mower. Old belt measures 90 inches but is in such bad condition and I am out of tension adjustment with a lot of room to adjust that I hope that will work correctly.
We sold this mower new in 82 when I was mechanic at IH dealer and I picked it up about 16 years ago. Not like new anymore but I alternate using it with a different mower. Use it in rough places as well as regular lawn on the old home farm place.
