High-Capacity 131-4556 Lawn Mower Grass Bag Replacement, Fits for Toro Models 20353 20355 20357 20960 20964 20965 21766 21767 21768 (NO Metal Catcher Frame)

What It Is

This is a replacement grass bag for Toro lawn mowers, designed to collect clippings during mulching or bagging. It fits select Toro models (20353, 20355, 20357, 20960, 20964, 20965, 21766, 21767, 21768) and is a high-capacity alternative to the OEM bag.

Fitment & Compatibility

Before buying, confirm your mower model number (found on a sticker under the seat or near the engine). This bag is not compatible with models that require a metal catcher frame—it attaches directly to the mower’s discharge chute. Measure your existing bag’s dimensions (roughly 24” x 18” x 12” for these Toro models). If your mower uses a frame, this bag will not fit. Compare the mounting bracket shape and hook style to your mower’s attachment point.

Key Things to Know

• Quality concerns: Only 1 review at 2.0/5 suggests poor fit or durability—expect possible loose seams or weak zippers.
• Installation: Easy—snaps onto the discharge chute without tools. No frame required, but ensure the bag’s hooks align with your mower’s tabs.
• Capacity: Larger than OEM, but may feel heavy when full. Check that your mower’s bagging system can handle the extra weight without sagging.
• Common gotcha: If your mower originally came with a metal frame, this bag will not stay attached properly. Verify your model’s bagging setup before ordering.

Should You Buy It

Only buy if you have one of the listed Toro models and your original bag is worn out—and you’re okay with a low-rated, potentially flimsy replacement. Otherwise, look for a higher-rated aftermarket or OEM bag with better reviews to avoid frustration.
