I checked with Oregon. Stated that don't make a blade for that Mower. Seemed strange that the exmark quest 42" would have some sort of special blade but that is what they saidOregon Gator Blades work very well on 'most' mower decks....
You can check this site OREGON brand Lawn Mower Blades
And search by blade size OR manufacturer.... :smile:KennyV
