Genuine OEM TORO PARTS - Grass Bag ASM 107-3789

What It Is

The Genuine OEM Toro Grass Bag ASM 107-3789 is a replacement grass collection bag designed for select Toro walk-behind mowers equipped with a side-discharge or bagging system. It’s intended for residential lawn care, capturing clippings during mowing to keep your yard clean.

Fitment & Compatibility

Before buying, verify your mower’s model number and deck size. This bag fits specific Toro models, primarily those with a 22-inch or 21-inch cutting deck, such as the Super Recycler, Recycler, and Personal Pace series (e.g., models 20332, 20333, 20334, and 20370). Check your mower’s model plate (usually under the rear flap or on the frame) and cross-reference with Toro’s official compatibility list. This is an OEM part, so it’s a direct replacement for the original bag—no modifications needed. Measure the bag mount width (approx. 12 inches) and ensure your mower’s bagger attachment matches. Aftermarket bags may be cheaper but often lack the exact fit or durability.

Key Things to Know

• Quality: Made from heavy-duty fabric with a rigid frame, it resists tearing and holds shape even when full. The zipper and handle are reinforced for long-term use.
• Installation: Simple—slides onto the mower’s bagger arm and clips into place. No tools required, but make sure the bag is fully seated to avoid clogs or spillage.
• Common Gotchas: This bag is only for models that originally used part 107-3789. If your mower has a different bagger system (e.g., rear bagger with a separate frame), it won’t fit. Also, check that the bag’s capacity (approx. 1.5 bushels) matches your mowing volume—overfilling can strain the attachment.
• Price vs. Value: At $92.89, it’s a premium OEM part. Aftermarket options may cost $40–$60 but often have thinner material or poor zipper alignment.

Should You Buy It

If you own a compatible Toro mower and need a durable, exact-fit replacement that won’t fail mid-season, this OEM bag is worth the investment. It’s ideal for homeowners who want hassle-free installation and reliable performance without modifying their mower. Skip it if you’re on a tight budget or have a different brand—aftermarket or universal bags might work, but expect trade-offs in fit and longevity.
