91-2258 V-Belt 3/8" x 35" Replaces Toro Recycler 22'' Drive Belt for Toro 20016, 20017, 20018 Self-Propelled Lawn Mowers, Replaces 91-2258 Drive Belt (1-Pack)

What It Is

This is a 3/8" x 35" V-belt that drives the self-propel system on Toro Recycler 22-inch mowers. It connects the engine pulley to the transmission, enabling the mower to move forward under its own power.

Fitment & Compatibility

Before buying, verify your mower’s model number (found under the seat or on the deck). This belt specifically fits Toro 20016, 20017, and 20018 (Recycler 22” self-propelled models). It replaces OEM part 91-2258. Measure your old belt: it must be 3/8” wide and 35” outside circumference. This is a genuine Toro belt, not an aftermarket alternative—no cross-reference needed for other brands. If your mower uses a different belt length or has a different deck size (e.g., 21” or 24”), this will not fit.

Key Things to Know

• Quality: Genuine Toro belt, built to OEM specs. Should last 2-3 seasons with normal use.
• Installation difficulty: Easy to moderate. You’ll need to remove the blade and belt cover, then route the belt around the engine pulley and transmission pulley. No special tools required.
• Common gotcha: Make sure the belt is seated properly in all pulley grooves and the tensioner is correctly engaged. A misaligned belt can cause slipping or premature wear.
• No universal fit: This belt is not a substitute for generic 3/8” x 35” belts—those may lack the correct profile or reinforcement for self-propel systems.

Should You Buy It

If you own one of the listed Toro Recycler 22” self-propelled models and need a direct OEM replacement, this is the correct belt. It’s reasonably priced, well-reviewed, and avoids fitment headaches of aftermarket belts. Not for other Toro models or non-Toro mowers.
