GANCO 131-4547-03 108-9764-03 Mulching Blades Replacement Part for Toro Recycler 20001 20003 Lawn Mower with 22" Deck (Pack of 2 Lawn Mower Blades)

What It Is

This is a pack of two aftermarket mulching blades designed for Toro Recycler mowers with a 22-inch cutting deck. They replace OEM part numbers 131-4547-03 and 108-9764-03, and are intended for fine grass clipping mulching rather than bagging or side discharge.

Fitment & Compatibility

Before buying, confirm your mower deck measures exactly 22 inches from blade tip to blade tip. These blades fit Toro Recycler models 20001 and 20003, as well as other Toro 22-inch Recycler mowers using the same OEM blade numbers. Each blade is 22 inches long, has a 1-inch center hole, and a 5-point star drive pattern. Check your current blade’s part number—if it matches 131-4547-03 or 108-9764-03, these will work. Not compatible with 21-inch or 24-inch decks.

Key Things to Know

• Quality vs OEM: Aftermarket blades may be slightly thinner or less balanced than genuine Toro. Inspect for burrs or uneven edges before installation.
• Installation difficulty: Easy—lift mower, remove center bolt, swap blades. Torque bolt to 50-60 ft-lbs. Use a blade stop or block to prevent rotation.
• Mulching performance: Designed for dry, moderate grass. Wet or tall grass will clump and reduce cut quality.
• Common gotcha: Star drive pattern must align perfectly with the adapter. If it’s loose, the blade will wobble and damage the spindle.

Should You Buy It

If you own a Toro Recycler 20001 or 20003 and want an affordable mulching blade set for regular, dry grass cutting, this is a solid budget option. But if you prioritize durability or have heavy-duty mowing conditions, consider OEM blades for better balance and longevity.
