105-6848-03 Accelerator-Blade Compatible with Toro Lawn Mower, for 21 in Super Recycler Mowers, Fits Models 20036 20037 20038 20039 20053 20054 20055

What It Is

This is an OEM Toro accelerator blade designed specifically for 21-inch Super Recycler mowers. It uses a unique curved shape and sharpened edge to create a vacuum-like airflow that lifts grass for a finer, more uniform cut, ideal for mulching or bagging.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 21 inches—this blade won’t fit 20- or 22-inch decks. It’s a direct OEM replacement for Toro models 20036, 20037, 20038, 20039, 20053, 20054, and 20055. Check your mower’s model number (usually on a sticker under the seat or on the deck). Measure the existing blade length (21 in.), center hole diameter (usually 1 in.), and thickness (about 0.15 in.) to match. This is genuine Toro, not aftermarket, so no adapter or modification needed.

Key Things to Know

• Quality: OEM part means exact fit and same steel grade as original; aftermarket blades may be thinner or dull faster.
• Installation: Easy—just one bolt (usually 5/8 in.). Torque to 60–70 ft-lbs. Sharp edges: wear gloves.
• Gotcha: The accelerator “wing” shape requires correct orientation—curved edge faces up toward deck. Wrong side up ruins cut and can damage mower.
• Performance: Best for mulching; if you side-discharge often, a standard lift blade may throw clippings farther.

Should You Buy It

Buy this if you own one of the listed Toro Super Recycler models and want a guaranteed fit with OEM mulching performance. It’s ideal for homeowners who prioritize a clean, fine mulch without bagging. If you only bag or side-discharge, a standard blade may work fine—but this is the right choice for your specific mower.
