What It Is

This is a set of two 22-inch mulching blades designed for Toro Recycler walk-behind mowers, replacing OEM part numbers 59534P, 104-8697-03, 108-9764-03, and 131-4547-03. They are intended for mowers that require a dedicated mulching blade to finely chop clippings and return nutrients to the lawn.

Fitment & Compatibility

Before buying, confirm these three things:

1. Deck size: Your mower deck must be exactly 22 inches. Measure the cutting width—not the overall deck width.
2. Model number: This set fits Toro Recycler models 20377, 20333, 20016, 20331, 20332, 21445, and 21465. Check the model tag under the seat or on the mower frame.
3. Center hole and offset: These blades use a 5-point star center hole (common on Toro) with a 1-inch diameter. The blades are flat (not offset) and have a 0.125-inch thickness. Measure your old blade’s center hole and overall length to verify.

OEM replacements are recommended for exact fit; these are aftermarket but match the listed OEM numbers.

Key Things to Know

• Quality: Aftermarket blades may be slightly thinner or less balanced than OEM. Inspect for warping or uneven edges before installation.
• Installation: Use a torque wrench to tighten the center bolt to 35–45 ft-lbs. Over-tightening can strip the spindle threads.
• Sharpening: These are mulching blades—sharpening is possible, but replacing them every 25–30 hours of use is simpler for consistent cut quality.
• Common gotcha: Mulching blades require a clean, dry deck to avoid clogging. Mow when grass is dry and don’t cut more than 1/3 of blade height per pass.

Should You Buy It

If you own one of the listed Toro Recycler models and want a budget-friendly replacement for worn OEM mulching blades, this two-pack is a solid value. It’s best for homeowners who mow regularly and prefer fine clippings that disappear into the lawn. Avoid if you need a bagging or side-discharge blade, or if you require OEM precision for commercial-grade use.
