Toro 2PK Genuine OEM Super Recycler Lawn Mower Blade 108-3762-03 93-4106-03

What It Is

This is a pair of genuine OEM Toro Super Recycler blades (models 108-3762-03 and 93-4106-03) designed for Toro’s Super Recycler walk-behind mowers. They create a finer, more consistent cut and better leaf mulching than standard blades by using a patented “recycling” airflow that recirculates clippings for extra shredding.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: These blades fit 21-inch and 22-inch Toro Super Recycler decks only. They will not fit standard Toro Recycler or non-Recycler models.
• Model number: Confirm your mower’s model number (e.g., 20370, 20371, 20378, 20379, 21370, 21371, 21378, 21379) matches Toro’s compatibility list. This set replaces part numbers 108-3762-03 and 93-4106-03.
• Center hole and spindle: The blades have a 7-point star center hole and a 1-inch diameter. Measure your spindle’s star pattern and width—if it’s a standard 5-point or round hole, these won’t fit.

OEM vs. aftermarket: These are genuine Toro blades, so fitment is exact. Aftermarket “compatible” blades may have slightly different star patterns or thicknesses, leading to vibration or poor mulching.

Key Things to Know

• Installation difficulty: Easy (10–15 minutes). You’ll need a 9/16-inch socket and a torque wrench (spec: 55–65 ft-lbs). Always use new blade bolts (Toro part 108-3761-03) to prevent loosening.
• Mulching performance: Expect noticeably better leaf shredding and finer clippings than standard blades, especially in dry grass. Wet or tall grass may still clump.
• Durability: These are heat-treated steel with a coated edge. They last about 25–30 hours of mowing before needing sharpening or replacement. Dull blades tear grass, causing brown tips.
• Common gotcha: The star pattern is fragile—never hammer or pry on the center hole. If it deforms, the blade won’t spin true and must be replaced.

Should You Buy It

If you own a Toro Super Recycler mower and want the best possible mulching, leaf shredding, and cut quality, these genuine OEM blades are the only correct choice. They’re pricier than aftermarket options but guarantee perfect fit, balanced performance, and the patented recycling action that aftermarket blades rarely replicate. Skip them if you have a standard Recycler or non-Toro mower—they won’t fit.
