What It Is

This is a replacement grass collection bag for select Toro 22-inch walk-behind lawn mowers, specifically models without a separate grass catcher frame. It attaches directly to the mower deck to collect clippings during mulching or bagging operations.

Fitment & Compatibility

Before buying, confirm your mower model: this bag fits Toro models 20378, 20330, 20331, 20370, 20371, 20377, and the XT675 (59307) series. It is not compatible with mowers that require a separate grass catcher frame. Measure your existing bag—this replacement is approximately 22 inches wide and attaches via a rigid plastic chute that hooks onto the mower deck. Check that your mower’s discharge opening matches the bag’s attachment shape; Toro’s 22-inch deck design is consistent across listed models, but older or non-listed variants may differ. This is an aftermarket part, not OEM Toro, so verify dimensions against your original bag if possible.

Key Things to Know

• Quality concerns: With a 3.3/5 rating from only 4 reviews, durability and fit may vary. Some users report the plastic chute cracks after a few uses or the bag doesn’t seal tightly, causing clippings to leak.
• Installation: Simple—slide the chute into the mower’s discharge opening and hook the bag’s top edge over the deck’s rear lip. No tools required.
• Common gotcha: This bag lacks a frame, so it relies on the mower’s deck for support. If your mower originally came with a frame, this won’t work—check your owner’s manual or look for a separate frame part like Toro 115-4663.
• Capacity: Holds about 1.5 bushels (roughly 12 gallons), sufficient for small to medium lawns. Expect to empty frequently on thick or wet grass.

Should You Buy It

Buy this if you need a budget-friendly replacement for a Toro 22-inch mower that uses a frameless bag and you’re okay with potential fit quirks or shorter lifespan. If you want guaranteed durability and a perfect seal, consider an OEM Toro bag instead.
