Quick Verdict
The aftermarket MTD Cub Cadet Twin Bagger Kit delivers a complete, largely pre-assembled grass collection system for 36″–46″ deck riding mowers at a price of $428 — well below what genuine OEM Cub Cadet bagger assemblies typically run. With a 4-out-of-5-star rating, full OEM cross-reference part numbers, and compatibility spanning Cub Cadet, Troy-Bilt, Craftsman, and the broader MTD brand family, it’s a smart buy for owners of 2020+ MTD-family tractors who want OEM-style function without the OEM price tag. It loses a point for aftermarket fit-and-finish inconsistencies and an overbroad compatibility list that requires careful verification before purchase.
Bottom line: If you own an MTD-family riding mower with a 36″–46″ deck and want to stop raking clippings, this kit is one of the most convenient and affordable ways to do it. Verify your model against the OEM part numbers below before ordering.

What’s Included in the Box
This isn’t just two bags and a chute — the kit is a turnkey solution that includes everything needed for a full installation:
- Two collection bags (OEM cross-references: 964-05104 / 964-04096A)
- Grass catcher hose (OEM: 764-05082)
- Double bagger support bracket (OEM: 683-04461C)
- Bagger flex hose ring (OEM: 731-12353A)
- Upper chute support (OEM: 731-06497)
- Bagger cover screen (OEM: 731-06504)
- Double bagger cover (OEM: 631-04292 / 931-04292)
- Installation instructions
The seller notes that most of the assembly has been completed prior to shipping, with only a few parts left for the buyer to attach. That’s a meaningful convenience — many competing bagger kits arrive as a box of loose hardware and brackets that can take well over an hour to assemble. If you ever need to service the system later, our guide to the Cub Cadet 764-05082 bagger flex hose covers replacement and the trade-offs involved.
Compatibility: Who This Bagger Fits
The compatibility list is extensive, which is both a strength and a potential source of confusion. The bagger is marketed for:
- Cub Cadet models including XT1-LT42, XT1-LT46, LTX1040, LTX1042, LTX1045, LTX1046, and many EFI variants
- Craftsman riding mowers with 42″–46″ decks (2010 and newer)
- Troy-Bilt models including Super Bronco 42/46, Bronco 42X, Bronco 46X, TB2246, TB2142, T8000, T8600, and more
- Yard Machines, Bolens, Huskee, MTD Gold, Columbia, White Outdoor, Remington, Brute, Mastercut, and Murray riding mowers with 42″–46″ decks
- MTD-family zero-turn mowers with 50″ and 54″ decks (2015 and newer) — though this reads like a separate compatibility note
The kit replaces a long list of OEM part numbers, including 19A30003000, 19A30003799, 19B30031OEM, CMXGZAMB30031, CMXGZAMA30045, and several others. If your mower’s deck falls in the 36″–46″ range and it was manufactured by MTD — which owns all the brands listed above — this bagger is very likely compatible. If you’re unsure what MTD ownership means for parts fitment, our explainer on what MTD stands for in lawn mowers breaks down the brand family tree.
Pro tip: Check your mower’s parts diagram before ordering. Every component in this kit carries an OEM cross-reference number, so you can match each piece to your model’s exploded view and confirm fitment before you even open a wrench.
Pros & Cons
What This Twin Bagger Gets Right
- Broad compatibility across dozens of mower models. Rather than being locked into a single brand, this bagger works with virtually every MTD-family riding mower produced over the last 15+ years. If you upgrade your mower in the future but stay within the MTD ecosystem, there’s a good chance this bagger transfers over — saving you from buying an entirely new collection system.
- Pre-assembled components reduce setup time. Instead of spending 60–90 minutes deciphering cryptic instructions and sorting through dozens of small parts, you can expect a significantly shorter installation. This is a genuine quality-of-life improvement over many competitors.
- Complete kit with all necessary hardware. Support bracket, flex hose ring, upper chute support, cover screen, and bagger cover are all included. Some competing products require you to purchase brackets, hoses, or mounting hardware separately, which drives up the total cost.
- OEM cross-reference part numbers for easy verification. Match each component to your mower’s parts diagram to confirm fitment before installation — no guesswork.
- Dual-bag design maximizes collection capacity. A twin bagger roughly doubles your capacity versus single-bag systems, meaning fewer stops to empty on medium to large yards. The two-bag layout also distributes weight more evenly across the rear of the mower, improving balance and traction.
- Significant savings versus OEM. Genuine Cub Cadet twin bagger assemblies often cost considerably more; this aftermarket kit delivers the same core function at a lower entry price.
Where It Falls Short
- Aftermarket, not genuine MTD/Cub Cadet. Fit and finish may not match OEM exactly; minor gaps, alignment tweaks, or shimming may be needed on some models.
- Overbroad compatibility list creates confusion. The inclusion of 50″/54″ zero-turn decks alongside 36″–46″ tractors suggests a generic listing — double-check your specific model.
- Premium price for an aftermarket kit. At $428, it’s still an investment; budget aftermarket single-bag options cost less, though with half the capacity.
- Bag fill-level visibility can be limited with enclosed twin covers, so you’ll need to gauge fullness by weight or airflow rather than sight.
Performance Notes
In use, a twin-bagger system like this one shines on medium to large lawns where clipping volume would otherwise require frequent stops or leave unsightly windrows. The dual bags roughly halve your emptying stops compared to a single-bag setup, and the balanced rear weight actually improves traction on slopes when the bags are loaded. Keep the mesh cover screen clear and the flex hose free of clogs — wet or very long grass is the enemy of any bagger’s airflow, so mow dry and at a moderate pace for best fill performance. For seasonal maintenance, inspect the flex hose (OEM 764-05082) and hose ring (731-12353A) for wear, as these are the first components to degrade on any bagger system.
Who Should Buy This Kit?
- Buy it if: You own a 2020+ MTD-family tractor (Cub Cadet XT1/LTX, Troy-Bilt Bronco, Craftsman 42″–46″) and want a near-OEM twin bagger without OEM pricing.
- Buy it if: You value pre-assembled convenience and a complete hardware package out of the box.
- Skip it if: You need guaranteed OEM warranty coverage or perfect factory fitment — buy the genuine Cub Cadet 19B30031OEM instead.
- Skip it if: You only bag occasionally; a mulching plug or single bagger may suit your needs at a lower cost.
FAQ
Will this bagger fit my Cub Cadet XT1-LT42?
Yes — the XT1-LT42 is explicitly listed among the compatible Cub Cadet models, along with the XT1-LT46, LTX1040, LTX1042, LTX1045, LTX1046, and their EFI variants. To be certain, cross-check your mower’s parts diagram against the kit’s OEM reference numbers (19B30031OEM and CMXGZAMA30045 are the primary ones).
Is this a genuine Cub Cadet / MTD product?
No. This is an aftermarket kit designed to replace OEM twin baggers on MTD-manufactured mowers. It replicates the function and fitment of the original equipment but is not manufactured by Cub Cadet or MTD directly. That’s why it’s priced below genuine OEM assemblies.
How long does installation take?
Significantly less than most aftermarket bagger kits, because the seller pre-assembles most components before shipping. Expect roughly 20–40 minutes of final attachment work — mostly mounting the support bracket, connecting the flex hose, and securing the cover — versus 60–90+ minutes for kits that ship as loose hardware.
What OEM part numbers does this kit replace?
The kit replaces 19A30003000, 19A30003799, 19B30031OEM, CMXGZAMB30031, CMXGZAMA30045, and several others. Individual components also cross-reference OEM numbers: bags (964-05104 / 964-04096A), hose (764-05082), support bracket (683-04461C), hose ring (731-12353A), upper chute support (731-06497), cover screen (731-06504), and bagger cover (631-04292 / 931-04292).
Does it work with zero-turn mowers?
The listing mentions MTD-family zero-turn mowers with 50″ and 54″ decks (2015 and newer) as a separate compatibility note, but the kit is primarily designed for 36″–46″ deck riding mowers and lawn tractors. If you own a zero-turn, verify fitment with the seller before purchasing rather than relying on the listing alone.
How often do I need to empty the bags?
It depends on lawn size, grass height, and moisture, but a twin-bagger setup roughly doubles the capacity of a single-bag system. For most homeowners with medium to large yards, that means noticeably fewer stops during a single mowing session. Empty the bags before they’re packed solid — overfilled bags reduce airflow and cause chute clogs.
Final Thoughts
The MTD Cub Cadet Double Bagger Kit for 36″–46″ decks is a well-rounded aftermarket solution that nails the fundamentals: broad MTD-family compatibility, a complete hardware package, OEM cross-reference transparency, and a mostly pre-assembled design that respects your time. At $428, it undercuts genuine OEM assemblies while delivering the same twin-bag capacity and fewer emptying stops. Its main drawback is the inherent
