161-8188 Lawn Mower Grass Bag Compatible with Toro 30 Inch TimeMaster Series Mower, Compatible Models 21219, 21220, 21491, 21493 Replaces Models 121-5770(Note:Grass bag does not include frame)

What It Is

This is a replacement grass bag (part 161-8188) designed for Toro 30-inch TimeMaster series mowers. It collects clippings during bagging operations and is a direct fit for models that require a bag without the frame assembly.

Fitment & Compatibility

• Deck size: 30-inch cutting deck only. Not for 21-inch or 22-inch Toro mowers.
• Compatible models: Toro TimeMaster 21219, 21220, 21491, 21493.
• OEM replacement: Replaces Toro part 121-5770. This is an aftermarket bag, not genuine Toro.
• No frame included: You must reuse your existing frame/hanger assembly. The bag alone will not attach without it.
• Check frame condition: If your frame is bent, rusted, or missing, this bag won’t work. Measure bag attachment points on your frame to confirm they match the bag’s hook/strap layout (typically two top hooks and a rear strap).

Key Things to Know

• Quality: At 3.8 stars from 4 reviews, it’s a budget option. Some users report thinner material than OEM, which may tear sooner under heavy use.
• Installation: Easy – slide the bag onto your existing frame, secure straps. Takes under 5 minutes.
• Common gotcha: The bag may sag slightly if the frame is worn, reducing capacity. Ensure your frame’s support bars are straight.
• Capacity: Same as OEM (approx. 2.5 bushels), but the fabric may not hold shape as well when full.

Should You Buy It

Buy this if you need a cheap, functional replacement bag for a Toro TimeMaster 30-inch mower and your existing frame is in good shape. It’s fine for light residential use. Skip it if you mow heavy, wet grass often or want OEM durability – invest in the genuine Toro bag instead.
