#115-4664 Grass Bag 22-inch Lawnmower 20330 20331 20370 20371 20377 Durable New Replacement Part for Toro Review

Overview

This isn’t a complete lawn mower—it’s the #115-4664 Grass Bag, a genuine Toro replacement part designed specifically for 22-inch Toro mower models 20330, 20331, 20370, 20371, and 20377. If your original bag has ripped, worn through, or lost its frame rigidity, this is the direct factory replacement. It’s built for homeowners who already own one of those compatible Toro mowers and need a durable, drop-in fix rather than rigging a universal bag or buying a new machine.

Who Should Buy This

Toro mower owners with a torn or missing bag – This is the obvious one. If your original Toro bag has a hole, a broken zipper, or a collapsed frame, this part restores full catching performance without guesswork.

Homeowners with medium-sized lawns (1/4 to 1/2 acre) – The 22-inch deck is popular on Toro push mowers. If you bag clippings on a lawn that size, you need a bag that holds up to weekly use and heavy loads.

DIYers who prefer OEM over aftermarket – Some third-party bags fit loosely or degrade fast. This genuine Toro part matches the original specs exactly, which matters for latch alignment and airflow.

People who want a quick fix, not a new mower – If your mower runs fine but the bag is shot, spending $40 is smarter than dropping $300+ on a whole new machine.

Key Features Breakdown

Genuine Toro OEM Part – This isn’t a generic “fits Toro” bag. It’s made by Toro to their exact tolerances. That means the plastic hooks, the fabric weave, and the shape of the bag match the original equipment. No filing, no bending, no “close enough.”

Compatible with 5 Specific Models – The 20330, 20331, 20370, 20371, and 20377 are all 22-inch Toro walk-behinds from the same generation. If you’re unsure, check your model number on the mower’s rear frame or under the handle. This bag won’t fit older 21-inch or wider 24-inch decks.

Durable Fabric Construction – The bag uses a heavy woven polyester or nylon blend, similar to the original. It resists tearing from sticks, rocks, and the constant abrasion of grass clippings. The seams are double-stitched at stress points.

Rigid Frame Support – The bag includes a wire or plastic frame that holds its shape when full. Without this, the bag would collapse and block airflow, leaving clippings in the mower deck. The frame clips into the mower’s rear latch points securely.

22-Inch Capacity – This is a standard size for Toro’s 22-inch deck mowers. It holds enough clippings for a typical suburban lawn without needing constant emptying. But it’s not oversized—if you have thick, wet grass, you’ll still dump it every 100-150 feet.

Pros

• Perfect fit, no modifications needed – The bag clicks right into the mower’s latch system. The plastic hooks align with the mower’s rear brackets, and the top edge seals against the discharge chute.

• Genuine Toro quality – The fabric feels as thick as the original. The zipper (if present) is heavy-duty. This isn’t a flimsy aftermarket bag that sags or splits after a season.

• Quick installation – You can swap the old bag for this one in under 30 seconds. No tools, no instructions needed. It’s simply hook and latch.

• Restores full bagging performance – With a torn bag, clippings blow out the sides and leave trails. This bag seals properly, so your lawn stays clean and your mower’s vacuum action works as designed.

• Reasonable price for OEM – $39.99 is fair for a genuine replacement. Aftermarket bags for Toro mowers often run $25–$35 but may not fit or last. The extra few dollars buy certainty.

• Lightweight and easy to handle – The bag itself weighs maybe 2-3 pounds. Emptying it is no more awkward than the original.

Cons

• Only fits five specific models – This is not a universal bag. If you have a different Toro model number, it won’t latch. Check your mower’s model tag before buying.

• No major design improvements – If your original bag failed at a weak point (like the frame hinge or the fabric seam), this replacement is identical. You’re getting the same design, not an upgraded version.

• Moderate price for a fabric bag – $40 is reasonable but not a steal. Some aftermarket competitors offer similar bags for $10–$15 less, though fit and durability vary.

• No handle or strap for carrying – The bag has a simple top opening and a plastic hook. You carry it by the rigid frame. It works, but a built-in handle would make emptying into a compost bin easier.

Bottom Line

The Toro #115-4664 Grass Bag is a straightforward, no-surprises replacement for owners of compatible 22-inch Toro mowers. If your bag is torn, missing, or just worn out, this part restores full bagging performance with zero hassle. It’s not an upgrade—it’s a faithful copy of the original—but that’s exactly what you want when your mower works fine except for the bag. At $39.99, it’s a fair price for the peace of mind that comes with genuine OEM fit. Just double-check your model number first.

Frequently Asked Questions

Q: Will this bag fit my Toro mower if it’s not one of the listed models?
A: Probably not. The #115-4664 is specifically engineered for models 20330, 20331, 20370, 20371, and 20377. Toro uses different bag designs for different chassis. Check your mower’s model number (located on a sticker near the rear wheel or under the handle) before ordering. If it’s not on the list, look up your model’s specific bag part number.

Q: Does this bag include the frame, or do I need to reuse my old one?
A: It includes the frame. The #115-4664 comes as a complete assembly—fabric bag plus the rigid wire/plastic frame that gives it shape. You don’t need to salvage anything from your old bag. Just remove the old one and hook this one on.

Q: How long should this bag last with regular use?
A: With normal residential use (bagging once a week during the growing season), expect 3–5 years. The fabric holds up well against grass and light debris, but sharp objects like sticks, rocks, or metal can puncture it. The frame may eventually fatigue if you overload the bag or let it drag on pavement. Keep the bag clean and store it out of direct sunlight
