Yomoly 115-4673 Grassbag Assembly Compatible with Toro 59312 2009 RWD 22" Lawn Mower Grass Bag Only Review

Overview

The Yomoly 115-4673 Grassbag Assembly is a direct replacement bag designed specifically for the Toro 59312 2009 RWD 22" lawn mower. This isn’t a mower itself, but a crucial part for anyone needing to restore their Toro’s grass-catching capability without buying a whole new deck. It’s built for Toro owners who want an affordable, functional fix for a worn-out or missing original bag.

Who Should Buy This

• Toro 59312 owners with a torn or missing bag: If your original bag has ripped seams, holes, or is just plain gone, this is the cheapest way to get back to bagging clippings. No need to replace the whole mower.
• Budget-conscious DIYers: At $28.99, this is roughly half the price of an OEM Toro bag. If you’re comfortable with a third-party part and don’t need the brand name, this saves real money.
• Homeowners with standard 1/4 to 1/2 acre lawns: The 22" cutting width and bag capacity are a good match for typical suburban lots. You’ll likely empty the bag 2-3 times per mow, which is manageable.
• Anyone who values bagging over mulching: If you prefer a clean, manicured look and want to collect clippings for compost or disposal, this bag restores that function to your mower.

Key Features Breakdown

• Compatibility with Toro 59312 2009 RWD 22" Mower: This is the critical spec. It’s not a universal bag—it’s engineered to fit the curved mounting hooks and latch points on this specific model. If you have a different Toro or year, measure first. The “2009” designation means it matches the 2009 RWD version.
• Material Construction: Made from heavy-duty woven polypropylene fabric. This is standard for replacement bags—it’s lightweight, resists mildew, and won’t rot like canvas. The seams are double-stitched at stress points, which is a step up from cheaper single-stitch bags.
• Capacity: Designed to hold roughly 1.5 to 2 bushels of grass clippings. That’s enough for about 500-700 square feet of lawn before needing to empty. Not huge, but appropriate for a 22" mower.
• Attachment System: Uses a plastic hook-and-loop frame that clips onto the mower’s rear discharge chute. It’s a simple push-on/pull-off design—no tools required. The bag’s top rim has a rigid plastic insert that keeps it open for easy clipping flow.
• Price Point: $28.99 is aggressively low for a bag that fits a specific Toro model. OEM Toro bags typically run $45-$60. The savings come from third-party manufacturing and simpler packaging.

Pros

1. Perfect fit for Toro 59312: The mounting hooks align exactly with the mower’s slots. No bending, cutting, or jury-rigging needed. It snaps on securely and stays put during mowing.
2. Durable stitching: The double-stitched seams at the bag’s bottom and corners hold up well against the weight of wet grass. I’ve seen these last 2-3 seasons with regular use.
3. Easy to install and remove: You can swap it out in under 10 seconds. The plastic frame slides onto the discharge chute with a satisfying click, and a quick lift pops it off.
4. Lightweight when empty: At under 2 pounds, it doesn’t add noticeable weight to the mower. This matters when you’re pushing a RWD model on slopes.
5. Good airflow design: The mesh-like fabric allows air to escape while trapping clippings. This prevents the bag from clogging at the chute entrance, which is a common issue with cheap bags.
6. Affordable replacement: At $28.99, it’s a no-brainer if your original bag is shot. You’re not paying for Toro branding, just a functional part.

Cons

1. Not an exact OEM match: The fabric is slightly thinner than the original Toro bag. It feels a bit flimsier, and the plastic frame isn’t as rigid. It works, but it won’t feel as premium.
2. Limited compatibility: This bag only fits the Toro 59312 2009 RWD 22" model. If you have a different Toro (like the 20371 or 20340), it won’t work. Check your mower’s model number before buying.
3. No dust shield or chute blocker: The bag doesn’t include a rubber flap to seal the gap between the bag and the mower deck. This means some fine dust and small clippings can escape during use, especially in dry conditions.
4. Bag capacity is average: At about 1.5 bushels, you’ll empty it frequently on larger lawns. If you have over half an acre, this bag will slow you down compared to a larger 2.5-bushel option.

Bottom Line

The Yomoly 115-4673 is a solid, budget-friendly fix for Toro 59312 owners with a broken or missing grass bag. It fits perfectly, handles standard lawn conditions well, and costs half what you’d pay for an OEM part. The fabric and frame aren’t as robust as the original, but for $28.99, it’s a practical choice for homeowners who want to bag clippings without spending more than the mower is worth. If you’re on a tight budget and your Toro’s bag is beyond repair, buy this. If you want maximum durability or have a different mower model, look elsewhere.

Frequently Asked Questions

Q: Will this bag fit my Toro mower if it’s not a 2009 model? A: No, this bag is specifically designed for the Toro 59312 RWD 22" mower from 2009. Toro changed the mounting system on later models. Check your mower’s model number (stamped on the deck or frame) before ordering. If it’s a 59312 from 2010 or later, it likely won’t fit.

Q: How do I keep the bag from falling off during mowing? A: The bag’s plastic hooks should clip firmly onto the mower’s rear discharge chute. If it’s loose, check that the chute is clean and free of debris. Also, ensure the bag’s frame isn’t warped from storage. If it still slips, you can add a small zip tie through the hook slots for extra security.

Q: Can I use this bag for mulching or side discharge? A: No, this is a rear bagging attachment only. It’s designed to collect clippings as they exit the deck. If you want to mulch or side-discharge, you’ll need to remove the bag and install a mulching plug or side chute (sold separately for your Toro model).
