Key takeaways
- Pro: The two-pack price undercuts most single-wheel OEM quotes significantly.
- Pro: Covers three legacy part numbers, reducing cross-reference confusion for older mowers.
- Con: Some owners report the tread pattern is less aggressive than factory, with a slight loss of grip in wet conditions.
What's inside
Troy Bilt mowers are common, affordable, and built to be serviced by their owners rather than shipped to a dealer. That makes the parts ecosystem the single biggest variable in how long a mower lasts and how much of its original cutting performance survives into later seasons. The practical problem: when a belt cracks, a blade bends, or a starter cord frays, a homeowner needs the correct replacement without spending more on the repair than the mower is worth, and without guessing whether an aftermarket part actually fits.
What separates a good replacement from a mediocre one in this category is narrow and specific. Correct OEM number matching matters more than brand name. Material thickness and rubber compound quality determine whether a belt or tire lasts one season or four. Installation complexity varies wildly—some parts need a socket set and ten minutes, others demand a deck removal. This roundup compares the eight most frequently purchased troy bilt lawn mower parts listings for 2026 on published fitment specs, listed price, and recurring themes in owner feedback.

How We Picked
We prioritized four criteria: exact OEM part-number match (a listing that replaces multiple valid numbers scores higher than one with vague compatibility claims), build quality as reported by repeat owners (material thickness, bearing fit, rubber grade), ease of installation without specialized tools, and price relative to OEM equivalents. Parts that solved a common failure mode at a fair cost ranked above those with marginal fitment advantages.
The 8 Best Troy Bilt Lawn Mower Parts in 2026
Front Drive Wheels (2-Pack)
These wheels replace OEM numbers 734-04018C, 734-04018A, and 734-04018B on self-propelled Tuff-Cut 210, TB210, TB230, and TB240 models. They also fit shared-hub MTD and Snapper platforms.
- Pro: The two-pack price undercuts most single-wheel OEM quotes significantly.
- Pro: Covers three legacy part numbers, reducing cross-reference confusion for older mowers.
- Con: Some owners report the tread pattern is less aggressive than factory, with a slight loss of grip in wet conditions.
Skip these if your mower uses rear-wheel drive or if the drive wheels are integrated into a transaxle assembly on a riding deck.
Side Discharge Chute (731-07486)
This chute fits most 21-inch hand-pushed mowers across Craftsman, Columbia, Huskee, Troy Bilt, and Yard-Man brands. Compatible models include the TB110, TB130, TB220, TB230, and the 11A and 12A series.
- Pro: Broad multi-brand compatibility means one listing covers dozens of platforms.
- Pro: Simple bolt-on install that requires only a Phillips screwdriver or small wrench.
- Con: A handful of owners note the plastic feels thinner than the original part, raising durability questions for heavy daily use.
Skip this if your mower already has a functioning bagger or mulching plug installed, since those configurations do not use a side chute.
Grasscool Mulching Blade (942-0741A)
Designed specifically for the Troy Bilt TB130 with its 21-inch deck. This mulching blade replaces the OEM 942-0741A directly.
- Pro: Pre-sharpened and balanced from the factory, so no resharpening needed before first use.
- Pro: Exact deck compatibility eliminates trial-and-error sizing for TB130 owners.
- Con: Single-purpose fitment limits usefulness if you own multiple mower sizes or brands.
Skip this blade if you prefer side discharge or bagging over mulching, or if your deck requires a high-lift blade for taller, wetter grass.
UDC Parts Deck Belt (954-04060C)
A 1/2-inch by 96.5-inch replacement deck belt for the Troy Bilt Pony 42-inch mower. Replaces OEM number 954-04060C.
- Pro: Kevlar-reinforced construction resists stretching better than all-rubber belts in this price tier.
- Pro: Correct width and length mean no adjustment to the idler pulley after install.
- Con: Routing the belt around the deck requires moderate mechanical confidence; first-timers may need a diagram or video.
Skip this belt if your Pony has a different deck size or if you need a transaxle drive belt rather than a deck belt.
15×6.00-6 Tire
A 15×6.00-6 turf tire compatible with various Craftsman and Husqvarna riding mowers. Useful on Troy Bilt riding decks sharing the same wheel size.
- Pro: Deep V-tread pattern provides solid traction on slightly sloped lawns.
- Pro: Universally common size means no proprietary hub adapter is needed.
- Con: Sold as a single tire, so replacing two wheels doubles the cost well above most other items here.
Skip this if your mower uses a different tire size—measure your sidewall before ordering, as 15-inch riding tires are not interchangeable with 6-inch drive wheels.
Kuupo Recoil Starter (593959)
A complete pull-start assembly for Troy Bilt TB110 and TB200 models equipped with Briggs and Stratton 140cc or 150cc engines. Replaces numbers 593959, 591139, and several B and S OEM codes.
- Pro: Arrives pre-assembled with spring and cord, so no rewinding is needed at home.
- Pro: Multi-number compatibility makes cross-referencing straightforward for older engines.
- Con: A few owners mention the housing plastic is softer than the original, with visible flex around the mounting tabs.
Skip this starter if your mower has an electric start or if the engine series is not among the listed B and S codes.
YzusGomumu Carburetor Kit
A bundled carburetor, spark plug, and air filter kit for mowers using B and S carburetors. Targets the most common cause of hard starting in small-engine mowers.
- Pro: Three-in-one approach eliminates separate purchases for a full tune-up.
- Pro: The carburetor comes pre-adjusted at the factory, reducing idle tuning time after install.
- Con: “Fit for B and S Carb” is a broad claim—verify your specific carburetor number before ordering to avoid gasket mismatches.
Skip this kit if your mower already starts easily and runs smoothly; it addresses fuel-delivery problems, not ignition or compression issues.
JYLEYJ Spindle Assembly (2-Pack)
Replaces OEM numbers 918-06991 and 618-06991 on Troy Bilt Pony 42-inch, Bronco 42, TB42, MTD, Craftsman T-series, and Huskee LT4200 decks. Sold as a two-pack to cover both spindles on a 42-inch deck.
- Pro: Bearing and pulley are pre-installed, so the spindle bolts straight to the deck with no press work.
- Pro: The two-pack price is lower than most OEM single-spindle quotes.
- Con: Replacing spindles requires removing the deck, draining or tipping the fuel tank, and often fighting rusted blade bolts—plan for an hour or more per side.
Skip this assembly if only one spindle is worn and your budget is tight, since buying a matching pair is not strictly required if the other bearing still spins freely.
Buying Guide
Match the OEM Number, Not the Model Name
Troy Bilt has used the same engine across multiple deck sizes and the same deck across multiple brand banners. A listing that states “replaces 942-0741A” is verifiable against your deck sticker; one that says “fits 21-inch Troy Bilt” is not. Always locate the part number stamped on the old component before ordering, especially for belts, spindles, and blades where dimensional tolerances are tight.
Evaluate Material Grade Within the Price Band
At under twenty dollars, a deck belt should specify Kevlar or polyester cord rather than plain rubber. A blade should arrive pre-hardened to a Rockwell range suitable for turf cutting. A spindle housing cast in aluminum will outlast stamped steel under the same load. Owner reviews mentioning “thicker than expected” or “flexes under hand pressure” are the most reliable free indicators of build quality.
Account for Hidden Labor Costs
Some parts swap in minutes with basic hand tools. Others—spindle assemblies, recoil starters on certain engine covers, deck belts on tight-routing Pony decks—demand additional equipment such as a spindle puller, torque wrench, or fuel-line clamps. When comparing a budget part against an OEM replacement, the gap in total repair cost narrows if the cheaper option requires a special tool you do not already own.
Our Verdict
Top pick: The JYLEYJ Spindle Assembly two-pack offers the best value-to-repair-ratio in this group. Spindle failure is the most expensive common Troy Bilt problem, and replacing both bearings for under fifty-five dollars eliminates the highest-ticket OEM repair most owners will ever face.
Budget pick: The UDC Parts Deck Belt at seventeen dollars solves the second-most-common Pony issue with minimal fuss and no special tools beyond a flathead screwdriver.
Condition where another part wins: If your mower will not start and you already suspect fuel-system gunk, the YzusGomumu Carburetor Kit outranks everything else here because a new blade or belt does nothing until the engine runs.
FAQ
How do I find the right part number for my Troy Bilt mower?
Check the white or silver model sticker under the deck, behind the seat, or on the engine shroud. For individual components, the number is usually stamped or molded directly into the old part—look on the back face of a blade, the sidewall of a belt, or the housing of a recoil starter.
Are aftermarket Troy Bilt parts as reliable as OEM?
In practice, aftermarket parts sourced from the same factories as OEM components perform identically for at least two to three seasons. The main risk is dimension drift in budget-tier belts and plastic housings, so owners report the best results with Kevlar-cord belts and pre-assembled starter units rather than the cheapest rubber-only options.
Can I use a Craftsman part on a Troy Bilt mower?
Often yes, because both brands share MTD or Briggs and Stratton platforms. Always verify by part number rather than brand name. For example, the side discharge chute here fits both Craftsman and Troy Bilt decks because it replaces a single shared OEM code.
What tools do I need for a typical Troy Bilt part swap?
Blade, wheel, and chute changes require a socket set, a block of wood to stop blade rotation, and optionally a torque wrench. Belt and spindle swaps add the need for a deck-tilt strap or jack stand. Recoil starter and carburetor work on top-mounted engines can usually be done with a Phillips screwdriver and a 5/16-inch nut driver.
