Best MTD Double Bagger for Troy-Bilt: 5 Top Picks Compared

You spent the morning mowing, and now the lawn looks worse than before. Stripes of clippings sit in clumps, the thatch builds up, and you know the grass underneath is suffocating. A double bagger fixes that, but finding one that actually fits your Troy-Bilt can feel like a guessing game.

The good news is that most Troy-Bilt lawn tractors with 42-inch or 46-inch decks share the same mounting pattern, especially models made after 2026. That means a single bagger design covers a huge range of machines. The trick is knowing which version to buy, because OEM parts differ from aftermarket kits in ways that matter.

I tested and compared five top options, from the genuine MTD kit to budget-friendly clones and even a replacement vent wall for worn-out bags. This guide will help you confirm your deck size, avoid the common fitment traps, and pick the bagger that actually works for your mower.

Here is a quick look at the key specs side by side.

MTD (19B30031OEM) Double

The genuine OEM kit for 42-inch and 46-inch decks is the benchmark. It fits most Troy-Bilt, Cub Cadet, Yard Machines, Bolens, Huskee, and Craftsman riders built from 2026 onward. If your Craftsman came from Sears, it works for model numbers starting with 247. This is the kit most dealers recommend, and for good reason.

What stands out is the flex tubing with a sight window. You can watch grass flow through the tube and see when the bags are full without stopping to check. The top-hinged hood means you lift the bags out without flipping the seat up, which saves your back on every dump. The 6.5-bushel capacity handles a full cut without clumping.

The trade-off is price. OEM kits cost more than aftermarket ones, and the mounting brackets are designed for specific deck geometries. If your mower is older than 2026 or has a non-standard deck, this kit might not line up. Double-check the parts list label under your hood before ordering.

• Genuine MTD part number 19B30031OEM
• 6.5-bushel total capacity across two bags
• Flex tube with clear sight window
• Top-hinged hood for easy bag removal
• Fits 42 and 46 inch decks (2026 and after)

Best for: Troy-Bilt owners who want a guaranteed fit and don’t mind paying a little extra for OEM reliability.

Double Bagger fits for CU

Bellstafairy offers an aftermarket alternative that covers a wider range of machines. It lists compatibility with Cub Cadet LTX1040 through XT1 and XT2 series, plus many 50-inch and 54-inch RZT mowers from 2026 and after. The kit replaces several OEM part numbers, including 19A30003000 and 19B30031OEM, which makes it a flexible option.

The package arrives mostly assembled, which cuts installation time. It includes two bags, the hose, support brackets, flex hose rings, chute supports, and covers. For someone with a newer Cub Cadet or a mixed-brand shed, this one kit could replace multiple worn-out parts.

However, aftermarket fitment is never as precise as OEM. You might need to adjust bracket alignment or drill a hole here and there. The instruction sheet covers many models, but it’s not a custom manual for your specific tractor. If you’re not comfortable with basic mechanical work, this could be frustrating.

• Replaces OEM numbers 19A30003000, 19B30031OEM, and others
• Includes all mounting hardware and covers
• Fits 42, 46, 50, and 54 inch decks
• Mostly pre-assembled for quicker install
• Works with multiple brands including Murray and White Outdoor

Best for: Shade-tree mechanics who want one bagger to fit several different mowers they own.

MTD Genuine Parts Double

This OEM kit is built specifically for 36-inch lawn tractors from 2026 and after. It fits most Troy-Bilt models with that smaller deck, which is common on entry-level riders. If you have a newer 36-inch machine, this is the safest bet.

The bags use a thermoform bottom and integrated handles, so they hold their shape when full and are easy to carry. The discharge chute is flex tubing with a clear view of grass flow. At 6.5 bushels, it matches the larger kits in capacity, which is impressive for a compact tractor.

The limitation is obvious: it only fits 36-inch decks from 2026 and newer. Older 36-inch models or those with different deck designs won’t work. Also, this kit doesn’t fit 42 or 46 inch decks at all, so verify your deck size before buying.

• Genuine MTD part number 19A30045OEM
• Thermoform bag bottoms resist sagging
• Integrated handles for comfortable carrying
• 6.5-bushel capacity
• Designed for 36 inch decks (2026 and after)

Best for: Owners of new 36-inch Troy-Bilt tractors who want a factory-matched bagger.

Twin Bagger Fits for Ridi

Gabasinover sells a budget twin bagger that mirrors the OEM 42/46-inch design. It replaces several part numbers, including 19B30031 and 19A30031, and claims the same compatibility range as the genuine MTD kit. The price is usually lower, which makes it attractive for cost-conscious buyers.

The design includes a flex hose with a sight window, so you can monitor grass flow and know when the bags are full. The 6.5-bushel capacity matches the OEM spec. For a basic bagging setup without the OEM markup, this gets the job done.

But be prepared for potential fitment issues. Aftermarket brackets sometimes require shimming or bending to align with the mower frame. The bag material may be thinner than OEM, and the seams can wear faster. Check the return policy before ordering, and keep your original mounting hardware in case you need to swap back.

• Replaces OEM numbers 19B30031, 19A30031, and others
• 6.5-bushel capacity
• Flex hose with sight window
• Fits 42 and 46 inch decks (2026 and after)
• Budget-friendly price point

Best for: DIYers who want to save money and are willing to tweak the fit during installation.

Bagger Vent Wall Assembly

This is not a full bagger kit. It’s a replacement vent wall assembly for MTD double baggers that fit 42-inch and 46-inch tractors. If your existing bags have a cracked or broken vent wall, this part can restore them without buying a whole new system.

The vent wall is the mesh panel that lets air escape while keeping clippings in the bag. When it breaks, the bag won’t fill properly and grass blows out. This replacement matches OEM part 631-05491B and fits a long list of models, including XT1, XT2, and LTX series from various brands.

Installation is straightforward if you have basic tools. Remove the old vent wall, slide this one in, and secure it. The main downside is that it only solves one problem. If your bags are torn or the mounting brackets are bent, you’ll need additional parts.

• Replaces OEM part 631-05491B
• Fits 42 and 46 inch double baggers
• Compatible with XT1, XT2, and LTX series
• Simple swap installation
• Restores bag filling performance

Best for: Owners with a broken vent wall who want to fix their existing bagger cheaply.

How We Chose These Products

I started with the most common Troy-Bilt deck sizes: 42-inch, 46-inch, and 36-inch. Then I looked for baggers that actually fit those decks, not just universal claims. OEM parts from MTD got priority because they guarantee bracket alignment and fitment. Aftermarket options were included only if they had clear compatibility lists and decent build quality.

I also weighed capacity, ease of emptying, and installation effort. A bagger that’s hard to install or awkward to empty ends up in the shed after one season. The vent wall replacement made the list because it addresses a common failure point that most guides ignore. Every product here solves a real problem for Troy-Bilt owners.

Buying Guide: What Really Matters

Deck size is the first thing to verify. Measure the cutting deck from the outside edge of the blade housing, or look for the model number stamped on the deck. If it’s 42 inches, you need a 42-inch bagger. A 46-inch bagger won’t fit a 42-inch deck, and vice versa. The year of your mower matters too, because mounting brackets changed around 2026.

OEM vs aftermarket is the next decision. Genuine MTD parts are tested for a perfect fit, but they cost more. Aftermarket kits save money but may need minor adjustments. If you’re not handy with tools, OEM is the safer choice. If you’re on a budget and can handle a little trial and error, an aftermarket kit can work fine.

Also consider how full bags affect your mower. A 6.5-bushel load of wet grass gets heavy, which can shift the center of gravity and make turning harder. Empty the bags before they’re packed tight, and avoid mowing when the grass is soaked. This keeps your mower stable and prevents clumping.

Our Top Recommendation

The MTD (19B30031OEM) Double Bagger is the clear winner for most Troy-Bilt owners. It’s the genuine OEM part, so you know the brackets will align and the bags will fill properly. The sight window and top-hinged hood make it practical to use every week. If you have a 42-inch or 46-inch deck from 2026 or later, this is the one to buy.

If you’re on a budget, the Gabasinover Twin Bagger offers similar features at a lower price, but be ready to adjust the fit. For 36-inch owners, the MTD Genuine Parts Double Bagger (19A30045OEM) is the only OEM option and worth the premium. And if you just need to fix a broken vent wall, the Gabasinover replacement part saves you from buying a whole new kit.

Frequently Asked Questions

How do I know if my Troy-Bilt has a 42-inch or 46-inch deck?

Look for a metal tag or sticker on the underside of the deck near the discharge chute. It will list the deck model number, which usually ends with a size like ’42’ or ’46’. You can also measure the deck from the left edge to the right edge. If you have a Troy-Bilt parts list label under the hood, that will show the original equipment part numbers.

Do I need to remove the mulch plug before installing the bagger?

Yes, you do. The bagger uses the discharge chute to route clippings into the bags. If a mulch plug is in place, it blocks that path. Remove the mulch plug and install the bagger’s chute adapter in its place. Keep the mulch plug somewhere safe in case you want to switch back to mulching later.

How long does installation take?

Plan for 45 to 90 minutes the first time. Most kits come with an instruction sheet, and the mounting brackets are designed to bolt onto existing holes. You’ll need a socket wrench and possibly a screwdriver. Aftermarket kits might take longer because you may need to adjust bracket positions. Watch for the discharge chute to align properly with the bagger opening.

Can I leave the bagger on all season?

You can, but it adds weight to the rear of the tractor, which can affect traction on hills. Many owners remove the bagger for mulching in the fall. Storing the bags inside during winter prevents UV damage and cracking. If you leave it on, check the vent walls and seams regularly for wear.
