(ET) drive belts

[<gmbauman alltel net>]

I have a New Idea 150 that I think is a GE 15 hp with a belly mower.  My 
problem is replacing the drive belts. Are the belts A, B, or C or are they 
3, 5, or 7 series belts.  There are two belts and I think they are a 
matched set. The belts that are on the tractor are what I call cog style, 
as they have dimples cut out of the webbing, so they go easier around the 
pulleys. Was original equipment cog style or full sided V belts? Any help 
you can give me will be greatly appreciated.
