Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Looking for spare Ariens belts for a 924071 (1986 ST1136), the parts radar app lists different ones 71,73,76... Does anyone have a proper lookup for these so I can get them sized and pick some up at the TSC? I don't want to measure the old ones because the machine was a little cobbled together so this might not be the appropriate size.

Thanks,

Craig
