105-8579 125-2466 Blade Bolt Compatible with Toro 22" Recycler Lawn Mower 105-8579 (3 Pack)

What It Is

This is a 3-pack of OEM Toro blade bolts (part numbers 105-8579 and 125-2466) designed to secure the blade to the spindle on Toro 22-inch Recycler lawn mowers. These bolts are essential for blade replacement and must be replaced each time you install a new blade to ensure safe, vibration-free operation.

Fitment & Compatibility

• Deck size: Fits Toro 22-inch Recycler mowers only (models like 20332, 20333, 20334, 20339, 20340, 20341, and similar 22" Recycler series).
• OEM vs aftermarket: These are genuine Toro bolts, not aftermarket. Confirm your mower uses part numbers 105-8579 or 125-2466 (check your owner’s manual or existing bolt).
• Measurements: Bolt is 5/16-18 thread, approximately 1.125 inches long, with a 9/16-inch hex head. Do not use on mowers with a different thread pitch or length.
• What to check: Verify your mower model number (stamped under the seat or on the deck) and that the bolt you’re replacing matches the thread and length. Using the wrong bolt can strip the spindle or cause blade wobble.

Key Things to Know

• Always replace bolts with blades: Toro recommends new bolts every time you swap blades to prevent fatigue failure. Reusing old bolts risks the blade detaching at high speed.
• Torque matters: Tighten to 35–55 ft-lbs (check your manual). Over-tightening can strip threads; under-tightening can cause blade slip.
• One bolt per blade: This 3-pack covers three blade replacements (one bolt each) or one mower with three blades (e.g., some 22" Recycler models use a single blade, so a pack lasts three changes).
• No lock washer needed: These bolts have a built-in lock washer or use thread-locking compound. Do not add extra washers—it changes the clamping force.

Should You Buy It

Buy this if you own a Toro 22" Recycler and want the correct OEM bolts for reliable, safe blade changes. It’s a good value for three replacements, saving you trips to the dealer. Avoid if your mower uses a different bolt size (e.g., 7/16-inch head or different thread) or if you prefer aftermarket bolts—though OEM is strongly recommended for safety.
