10 Best Troy-Bilt Lawn Mower Replacement Parts to Buy in 2025

Finally, a no-nonsense solution for one of mowing’s most common frustrations. This abundant nine-piece set of spindle blade nuts immediately solves the problem of misplacing or stripping the single, crucial nut that holds your blade in place. Crafted from durable steel with a precise 5/8″-18 thread size, these hex flange nuts provide the robust tightening effect needed to ensure your mower blades operate smoothly and safely. For any DIYer who frequently sharpens or replaces blades, having this multipack on hand transforms a potential project-stopping issue into a minor inconvenience.

In real-world use, the value of having multiple spares becomes instantly clear. Whether you’re swapping blades mid-season on your Troy Bilt or performing maintenance on a family member’s Craftsman, these nuts perform flawlessly, gripping the spindle with confidence. Their wide compatibility across MTD-family brands means a single purchase covers multiple machines, and the steel construction holds up to the torque of an impact wrench without complaint. They are a fundamental Troy bilt lawn mower replacement part that feels more substantial than many OEM nuts, preventing the dreaded rounding-off that plagues lesser quality hardware.

Compared to a specialized repair item like the Lawn Mower Blade Adapter Kit, this Zhengmy nut set is about preparation and routine maintenance rather than catastrophic failure repair. While the adapter kit is a one-time fix for a major impact, this nut set is the consumable part you’ll need again and again. For those who value readiness and efficiency, having this bulk pack offers far greater long-term utility than buying single, over-packaged nuts from a big-box store.

Revitalize your mower’s responsiveness with the XIKOBY 946-04661A control cable, an essential fix for a sluggish or non-engaging engine. This part masterfully addresses the common failure point of a stretched or snapped throttle cable, restoring crisp control to your self-propelled mower. Engineered with a 51-inch total length and durable Z-type bends on each end, it’s a perfect-fit replacement for a huge range of mowers, including the popular Troy Bilt TB110 and Craftsman M230 models. The inclusion of zip-ties is a thoughtful touch that simplifies a clean and secure installation.

During testing, the cable’s performance was indistinguishable from an original factory part, immediately fixing the throttle lag on an aging Yard Machines mower. The 37.5-inch conduit length provides the correct amount of slack for routing along the mower handle without binding or kinking, a critical detail for smooth operation. This replacement cable allows the engine to activate properly, turning a frustrating, hard-to-manage machine back into a reliable workhorse. It’s a straightforward repair that makes a world of difference in your mower’s usability.

When choosing between operator control parts, the XIKOBY cable solves a different problem than the BERPSE Bail Operator handle. The BERPSE handle fixes a physical interface failure, while this XIKOBY cable corrects the internal mechanical linkage that actually controls the engine. If your handle feels fine but the mower won’t respond, this cable is the likely culprit, offering a more targeted and affordable repair than replacing the entire handle assembly.

Instantly restore the most critical safety and operational feature of your push mower with the BERPSE 747-05214D Bail Operator. This handle actuator is the definitive fix for a broken, bent, or missing engine-kill bar, a common failure that renders a mower completely useless. Its vibrant red finish and precise geometry make it a direct, drop-in replacement for dozens of Troy-Bilt, MTD, and Craftsman models, eliminating any guesswork. For homeowners facing a mower that won’t stay running, this part is the simple solution that gets you back to cutting grass in minutes.

The installation process is refreshingly simple, requiring minimal tools to swap out the old, failed part. Once in place, the BERPSE bail handle provides the correct tension and engagement to keep the engine running smoothly when held and to stop it immediately upon release. This isn’t just a convenience part; it’s a fundamental safety component that ensures your machine operates as designed. Its sturdy construction feels robust and ready to withstand seasons of use, a noticeable upgrade over flimsy, aged original parts.

Unlike the XIKOBY Control Cable which manages engine speed, the BERPSE Bail Operator is the mower’s primary user engagement and safety switch. If your mower’s handle itself is snapped, this is the part you need, whereas a functioning handle with no engine response points toward the cable. This BERPSE handle offers a more comprehensive fix for physical damage to the operator controls, ensuring both function and safety are fully restored.

Unleash your mower’s full potential with this essential 731-07486 Side Discharge Chute, designed to restore a key cutting function to your machine. This component is the perfect solution for anyone who has lost or broken their original chute, forcing them to mulch or bag when conditions are better suited for side-discharging. With an 11-inch hypotenuse length, it’s engineered to fit a massive range of 21-inch push mowers, including many popular Troy-Bilt TB110 and TB130 models. It effectively directs clippings away from the deck, preventing clumping and ensuring a cleaner cut in taller, thicker grass.

In practice, the chute attaches easily, though you must reuse your original mounting hardware. It channels grass clippings in a neat, even pattern, a vast improvement over the messy discharge from a mower deck without a chute. This is particularly noticeable when tackling overgrown areas where mulching would bog down the engine. This chute is one of those simple Troy bilt lawn mower replacement parts that dramatically improves the quality and efficiency of your mow under specific conditions.

While a functional part like the CheeMuii Lawn Mower Wheel is essential for the mower to move at all, this Side Discharge Chute is about optimizing the result of the mow. The wheels get you across the lawn, but this chute ensures the lawn looks its best afterward by managing clippings effectively. For users who need versatility beyond just mulching, this chute provides a better functional value than many other cosmetic or minor mechanical parts.

Effortlessly glide across your lawn again with the CheeMuii 734-04018 replacement wheels, a robust solution for worn-out or broken mower wheels. This two-pack directly addresses the wobbling, dragging, and uneven cutting caused by degraded front wheels on self-propelled mowers. Featuring an 8-inch diameter and a 2-1/8-inch width, these wheels are built with a durable plastic core and a solid rubber tread for superior traction and longevity. The 1/2-inch bore ensures a snug, perfect fit on a wide array of Troy Bilt models, including the hard-working TB240.

During real-world testing on uneven terrain, these wheels provided a noticeably smoother and more stable mowing experience. The aggressive tread pattern grips damp grass effectively, preventing the front end of the mower from slipping or sliding on inclines. Replacing cracked or bald original wheels with this CheeMuii set instantly improves the mower’s maneuverability and helps maintain a consistent cutting height. This is a critical repair that not only makes mowing easier but also enhances the final look of your lawn.

Both these CheeMuii wheels and the 591139 Recoil Starter are essential for a mower’s basic operation, but they solve fundamentally different problems. A broken starter prevents the job from ever beginning, making it a power system failure. Worn wheels, however, represent a mobility system failure, making the job frustrating and producing poor results. For mowers that start fine but are a chore to push, these wheels offer a higher-impact upgrade for improving the user experience.

Bring your dead mower roaring back to life with this complete 591139 Recoil Starter Assembly. This is the ultimate fix for the dreaded snapped pull cord or a recoil spring that refuses to retract, problems that can sideline your mower instantly. Designed as a direct replacement for Briggs & Stratton 593959 and 591139, it fits a massive range of popular 140cc and 150cc engines found on Troy Bilt, Craftsman, and Yard Machines mowers. The entire assembly comes ready to install, saving you the immense frustration of trying to re-wind a powerful spring by hand.

Installation is a breeze—simply unbolt the old, broken unit and screw this new one into place. Within minutes, your mower’s starting mechanism is fully restored. The pull handle is ergonomically designed for a comfortable grip, and the retractable cord mechanism feels smooth and responsive, engaging the engine flywheel with decisive force. For anyone with a compatible mower like the Troy Bilt TB110, this replacement part is a game-changer, turning a potentially costly repair shop visit into a quick DIY task.

Compared to a maintenance item like the Lawn Mower Air Filter kit, this recoil starter solves an acute, job-stopping failure. While the air filter kit is for preventative care and optimizing performance, this starter is an emergency mechanical repair. If your mower won’t even turn over, this is the part that provides immediate value, getting your essential equipment running again without delay.

Recover from a catastrophic blade impact with this indispensable Lawn Mower Blade Adapter Kit. This is the critical component that links your mower’s blade to the engine crankshaft, and it’s specifically designed to be the failure point to protect your engine from severe damage. This all-in-one kit includes the star-patterned 748-0376E adapter with a 23MM center hole, a new 710-1044 hex bolt, and the 736-0524B bell support washer. It’s the complete solution for when you hit a rock or root and your blade stops spinning true, saving your mower from the scrap heap.

In a workshop setting, having all three components in one package is a massive time-saver. The adapter fits snugly onto the crankshaft, and the new bolt and washer ensure you get the correct clamping force without reusing potentially stressed or damaged hardware. This kit is a must-have for any serious DIYer, as a damaged adapter can cause dangerous vibrations and poor cut quality. This is one of the most important Troy bilt lawn mower replacement parts for ensuring the long-term health of your machine’s engine.

This Blade Adapter Kit addresses a much more severe issue than the Zhengmy Spindle Blade Nut set. The Zhengmy nuts are for routine fastening and replacement, while this adapter kit is for rebuilding the entire blade mount assembly after a significant impact. If your blade is wobbly or vibrates violently after hitting an object, this kit is the non-negotiable fix, offering a complete repair solution that goes far beyond just a simple fastener.

Execute a complete engine tune-up with one convenient package using this comprehensive maintenance kit. This bundle is intelligently curated to provide everything needed for an annual service on popular Briggs and Stratton engines, including the workhorse 550ex and 675exi series. The kit includes a high-quality 593260 air filter, a fresh spark plug, two oil filters, and even a fuel line with clamps. It’s the perfect all-in-one solution for proactive owners looking to boost engine efficiency, ensure reliable starting, and extend the life of their Troy-Bilt or Craftsman mower.

Each component in the kit fits and performs just like its OEM counterpart. The air filter, made with high-quality paper and a pliable rubber seal, effectively traps dust and debris, protecting the carburetor and engine internals. Paired with a new spark plug, it solves common issues like hard starting, rough idling, and power loss. This kit turns a trip to the store for multiple, individual parts into a single, smart purchase that covers all the bases for peak engine performance.

This kit offers a starkly different value proposition than the Harbot 491588S Air Filter pack. While the Harbot product provides excellent value if you only need an air filter, this maintenance combo is a complete seasonal overhaul solution. For someone looking to perform a full tune-up on their Troy-Bilt TB200, this kit is the superior choice, providing all necessary components for a deeper level of engine care in one go.

Maximize your engine’s breathing room and efficiency with the Harbot 491588S Air Filter two-pack. This replacement part is a targeted upgrade for mowers running rough due to a clogged or dirty air filter, a common and easily fixable problem. Engineered for a perfect fit in 3.5-6.5 HP Quantum engines, this flat cartridge filter boasts an impressive 99% filtration efficiency. The highly elastic polyurethane seal creates a tight fit within the housing, preventing unfiltered air from bypassing the element and ensuring your Troy-Bilt TB110 or TB230 engine is protected from harmful debris.

The benefit of replacing a clogged filter is immediate and tangible; the engine starts easier, idles smoother, and delivers more consistent power, especially under load. With dimensions of 5-3/16″ L x 4-1/2″ W x 13/16″ H, it drops right into place with no tools required, making it one of the simplest and most effective maintenance tasks you can perform. Having a second filter on hand means you’re already prepared for your next service, adding a layer of convenience and value.

Unlike the all-in-one Lawn Mower Air Filter maintenance combo, the Harbot two-pack is a specialized purchase focused solely on air filtration. If you’ve recently changed your spark plug and oil, this Harbot pack is the more economical and logical choice, providing a higher-quality, dedicated component for the most frequent tune-up need. It offers better long-term value for users who prefer to buy their maintenance parts a la carte.
