Toro Grass Bag Asm Part # 119-3759

What It Is

The Toro Grass Bag Assembly Part # 119-3759 is a replacement bag for select Toro walk-behind mowers. It collects clippings during mulching or bagging operations and is designed for residential use on mid-size decks (typically 22-inch).

Fitment & Compatibility

Before buying, verify your mower’s model number—this bag fits specific Toro models like the 20334, 20335, 20337, and 20340 (all 22-inch Recycler series). It does not fit older models or other brands. Measure the bag mounting bracket on your mower: this assembly uses a rigid plastic frame with two side hooks and a rear latch. If your mower has a different attachment system (e.g., pin-style or strap), this won’t work. OEM-only—no aftermarket equivalents available. Check your owner’s manual or Toro’s online fitment tool using the part number.

Key Things to Know

• Quality concerns: With a 3.2/5 rating from only 3 reviews, some users report the bag’s fabric tears at seams after a few seasons, especially under heavy use.
• Installation difficulty: Easy—slides onto the mower’s rear bracket and latches in place. No tools required.
• Common gotcha: The bag’s capacity is smaller than some older Toro bags (about 1.5 bushels). If you mow a large lawn, you’ll need to empty it frequently.
• Price: At $63.70, it’s moderately priced for an OEM bag. Cheaper generic bags exist but won’t fit without modification.

Should You Buy It

Buy this bag if you own one of the listed Toro 22-inch Recycler models and need a direct, no-hassle replacement. Skip it if you’re on a tight budget, mow a large lawn requiring fewer empties, or want a bag that’s more durable than the factory option—consider a metal-framed aftermarket bag instead (though fitment may require adapters).
