161-8188 Lawn Mower Grass Bag for Toro 30" Time Master Grass Catcher Bag, Fits Models 20199 223CC 20200 20975 20976 21199HD 21810 - Replaces Part 121-5770 (Frames are Not Included)

What It Is

This is a replacement grass bag for Toro 30-inch TimeMaster mowers, designed to catch clippings during mulching or bagging operations. It’s a direct replacement for the original bag on walk-behind models with a 30-inch cutting deck.

Fitment & Compatibility

Before buying, confirm your mower’s model number matches one of these: 20199, 20200, 20975, 20976, 21199HD, or 21810. The bag fits Toro TimeMaster 30-inch decks only—not the 22-inch or 42-inch models. It replaces OEM part 121-5770, but frames are not included; you must reuse the existing metal frame from your old bag or purchase a separate frame (part 121-5770 frame assembly). Measure the bag opening to ensure it aligns with your mower’s discharge chute—standard for 30-inch decks, but verify if you have an older or modified machine.

Key Things to Know

• No frame included: You need the metal support frame from your old bag or buy it separately. The bag alone won’t attach to the mower without it.
• Installation is straightforward: Slide the bag onto the frame, then hook it to the mower’s rear bracket. Takes about 5 minutes.
• Durability: Made of heavy-duty fabric with a plastic top rim; holds up to regular use but avoid overfilling to prevent tearing.
• Capacity: Holds roughly 2–3 bushels (enough for a typical lawn without emptying too often), but wet grass will fill it faster.

Should You Buy It

If you own a Toro TimeMaster 30-inch mower (models listed above) and your original bag is worn, torn, or missing, this is the correct OEM replacement at a fair price. It’s a simple swap if you keep the old frame, but factor in a separate frame purchase if you don’t have one. Best for homeowners who bag clippings regularly and want a direct fit without aftermarket guesswork.
