I'm trying to find a set of blades for my mom's Ariens GT20 tractor. It has a 42" deck. The OEM number is 0312-1359 which supersedes to 0312-1300. She actually would like to find a set of mulching blades, but she's going to need something by the end of the season.. The blades are 14 11/16"...

Hi All I got an Ariens 42" mower with the GT18 I purchased this spring. It works fine, but I'm finding that a little wider mower deck would work better for me. I have several decks off other machines--a couple off older CC Narrow Frames, and one from a Ford LGT-series tractor. How hard is it...
