133-2630 Side Discharge Cover Assembly Compatible with Toro 20976 21219 20978 21199 21200 21220

What It Is

This is a side discharge cover assembly (OEM part 133-2630) that closes the side chute opening on select Toro walk-behind mowers, converting them to mulching or bagging mode. It’s for Toro models with 22-inch stamped steel decks.

Fitment & Compatibility

Before buying, verify your mower’s model number (not serial). This cover fits Toro models 20976, 21219, 20978, 21199, 21200, and 21220. It is designed for 22-inch deck widths only. Measure your deck’s side discharge opening width and compare to the cover’s flange. The cover is OEM Toro, not aftermarket, so it should match factory dimensions. Check that your mower uses a single hinge pin and spring latch—some older Toro models use a different retention system.

Key Things to Know

• Quality: OEM part, but 3.4-star rating (3 reviews) suggests possible fitment issues or brittle plastic. Inspect for cracks on arrival.
• Installation: Easy—typically snaps on with one hinge pin and a spring clip. No tools needed, but the spring can be stiff.
• Gotcha: The cover may be loose on decks with worn hinge holes. If your original cover rattled, check the deck’s hinge pin hole diameter before buying.
• Compatibility: Only for the listed models. Using it on a different Toro deck may cause poor sealing, leading to grass clippings escaping.

Should You Buy It

Buy this if you own one of the listed Toro models and need an exact OEM replacement for a lost or broken side discharge cover. Skip it if your deck has significant rust or wear around the hinge area—you might need a whole deck or a universal cover instead. For $24, it’s a reasonable fix if fitment is confirmed.
