91-2258 V-Belt 3/8" x 35" for Toro Recycler and Super Recycler Self-Propelled Lawn Mower 20016 20017 20018, Replaces Toro Self Propelled Drive Belt 91-2258

What It Is

This is a 3/8" x 35" V-belt that drives the self-propel system on Toro Recycler and Super Recycler walk-behind mowers. It connects the engine pulley to the transmission, moving the mower forward without pushing.

Fitment & Compatibility

• Check your model number: This belt fits Toro models 20016, 20017, and 20018 (Recycler/Super Recycler). Verify your mower’s model number on the chassis or under the rear flap.
• Measure your belt: If the old belt is frayed or broken, measure the length and width. This belt is exactly 3/8" wide and 35" long. A different size won’t fit properly.
• OEM vs aftermarket: This is a genuine Toro belt (OEM part 91-2258). Aftermarket versions exist but may wear faster or slip—stick with Toro for reliability.
• Deck size not relevant: This belt is for the self-propel system, not the blade drive. Deck size (22" or 24") doesn’t affect compatibility.

Key Things to Know

• Installation is moderate difficulty: You’ll need to remove the mower deck and belt cover, then route the belt around the engine pulley and transmission pulley. A diagram helps—check your manual.
• Check tensioner and pulleys: A worn tensioner spring or seized pulley will cause the new belt to fail quickly. Inspect and replace if needed.
• Common gotcha: The belt can slip off if the idler pulley is misaligned or the belt is not seated fully in the pulley grooves. Double-check routing before reassembly.
• No special tools required: Basic socket set and screwdriver are all you need. Allow 30–45 minutes for a first-time install.

Should You Buy It

If you own a Toro Recycler or Super Recycler (models 20016–20018) and your self-propel drive is slipping or dead, this belt is the correct fix. It’s a genuine OEM part at a fair price, with strong reviews confirming fit and durability. Not for other mower brands or blade drive systems.
