Toro Part # 108-9792 Grass Bag Assembly

What It Is

The Toro Part # 108-9792 Grass Bag Assembly is a replacement collection bag for select Toro walk-behind mowers with a 22-inch steel deck. It’s designed to catch clippings during mulching or bagging operations.

Fitment & Compatibility

• Check your model number: This bag fits Toro models like the 20064, 20065, 20069, and 20333 (22" Recycler or Super Recycler series). Verify your mower’s model number on the deck or in your manual—don’t rely on deck size alone.
• OEM vs aftermarket: This is a genuine Toro part, not a universal or third-party bag. Aftermarket bags for these models may have different dimensions or latch designs, so stick with OEM unless you measure carefully.
• Measurements: The bag is roughly 22 inches wide and 12 inches deep. Check that your mower’s bagger mounting bracket and discharge chute match this size—older or non-Recycler models often won’t.
• Deck size: Only for 22-inch decks. Fits 21-inch or 20-inch decks? No—the bag’s shape and latch points are specific to 22-inch steel decks.

Key Things to Know

• Build quality: Users report the bag’s plastic frame cracks after a season or two, especially around the hinge points. The fabric bag itself holds up okay, but the frame is a weak link.
• Installation difficulty: Easy to swap—unhook the old bag, slide the new one onto the mower’s mounting pins, and secure the latch. No tools needed.
• Common gotcha: The bag’s top opening may not seal tightly against the discharge chute on older mowers, causing clippings to blow out. Check the rubber flap on your mower’s chute—if it’s worn, replace it too.
• Price vs reviews: At $112 with a 1.9-star rating, it’s expensive for a part that may need replacing within 2-3 years. The low score likely reflects durability issues, not fitment problems.

Should You Buy It

Buy this only if you own a compatible 22-inch Toro Recycler and your original bag is torn or missing its frame. If your bag frame is still intact but the fabric is ripped, consider replacing just the fabric bag (Toro part # 108-9792-03) for less. If you’re on a tight budget or want a sturdier option, look for aftermarket bags with reinforced frames—but measure twice first.
