Toro 6PK Genuine OEM 21" Lawn Mower Blade 133-8182-03 108-0954-03

What It Is

This is a 6-pack of Toro genuine OEM 21-inch mower blades (part numbers 133-8182-03 and 108-0954-03), designed for 21" walk-behind Toro mowers with Recycler or Super Recycler decks. They replace dull or damaged blades to restore cutting performance and mulching quality.

Fitment & Compatibility

• Deck size: Only fits 21" decks – measure your blade length to confirm.
• Model fit: Compatible with Toro Recycler (e.g., 20333, 20339) and Super Recycler models (e.g., 20900, 20901). Check your owner’s manual or current blade part number.
• OEM vs aftermarket: These are genuine Toro blades, not universal. Aftermarket blades may fit but often lack the specific lift and mulching profile for Toro decks.
• Measurements: Blade length 21", center hole diameter 1", blade thickness ~0.15". Verify these against your old blade before ordering.
• Hardware: Check that your mower uses a 5/16" bolt (common on Toro) and that your blade adapter/center hole matches.

Key Things to Know

• Mulching performance: These blades have a high-lift design for fine mulching. If you bag or side-discharge, they work well but may throw clippings farther than low-lift blades.
• Installation difficulty: Easy – just remove the bolt, replace the blade, and torque to 35-45 ft-lbs. Use a blade stop tool or wedge wood to prevent spinning.
• Common gotcha: The 6-pack is cost-effective for multiple mowers or frequent changes, but single blades are available if you only need one. Check your mower’s blade count (most 21" Toros use one blade).
• Sharpness: These come unsharpened from the factory – you may need to sharpen before first use for optimal cut quality.

Should You Buy It

Buy this if you own a 21" Toro Recycler or Super Recycler mower and want guaranteed fit and mulching performance. It’s ideal for commercial users or homeowners with multiple Toro mowers who need a bulk supply. If you only need one blade or have a different brand deck, skip it – aftermarket or single OEM blades are cheaper and more practical.
