There are Toro part numbers on those Oregon blades. Your Toro part number isn’t there. They may work out for you anyway. If the blades are slightly tucked inside of the deck, that’s a good thing. Toro blades will sit somewhere between 1/4” to 3/8” above the bottom deck lip. They may also be 1/16” shorter than your Toro blades. If that’s the case, you may notice an uncut strip of grass in the middle of the rows that you’re mowing. You won’t know, unless you try them.
