I use a standard v belt on my 453. You can order a B47 from McMaster Carr. http://www.mcmaster.com/#b47-v-belts/=dxzn08B-47 is a standard size, have you tried an auto store? it should be easily available, you may even have the option of raw edge or a power rated belt. I use this sort on my ride on mower for the cutting deck.
“B” section V belts are 3“ longer than the number. A B47 belt has a 50” outside circle. A 5L500 belt would also work its 50“ and the same top width.Are you sure about the 47" belt? My 440B used a 49" belt back when it had a Kohler in it. I bought my last belt at TSC, works fine. HTH - SR
Thanks for all the help. i went to carquest and got a B-47 belt 50" long. i save a lot of money....“B” section V belts are 3“ longer than the number. A B47 belt has a 50” outside circle. A 5L500 belt would also work its 50“ and the same top width.
