If your 5-foot finishing mower (like a Caroni, Maschio, Sitrex, LMC, Curtis, or Del Morino) is making squealing noises or the belt snapped, this 2-pack is likely what you need. These are brand new replacement drive belts that fit a bunch of popular mower brands. MPNs listed include 1380, 00557022, 600.139, 42800002, 542003 – so check your old belt's number. They come in their original packaging. Having a spare is always smart when you're in the middle of mowing season. Installation varies by mower, but usually involves loosening a tensioner and sliding the new one on. Keep your equipment running smoothly and avoid downtime. Essential for any farmer or landscaper with one of these mowers.
