Whats the belt supposed to go onto?

its for my old attex 6 wheeler. it uses a snowmonile type drive belt. a few years back i stole the belt off an old artic cat puma, and cut the sides down to fit, and after it ran awhile it cleaned up nice. but i just recently found what belt it used originally, and wanted to get something close.
