Make and model? Is belt good, not pieces missing? Does the belt run smooth, or is there a high vibration? Usually breaking springs is caused by vibration due to belt not running true.

Belt seems okay but I will replace and try again and let you know. Ill also check pulley for loose. Toro time cutter z480 74352

Belt is good. Pulley tight and not broken. All looks smooth. So don't no what else would cause it.

So spring looks to be just holding, not vibrating up and down? All you can do is try it again!
