The Troy-Bilt TB240 price depends mostly on whether the mower is used, refurbished, or remaining new old stock. Used examples commonly fall around $100-$275, while a clean, working mower or boxed leftover may cost more; engine condition, included features, and local availability shape the final price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Used TB240 mower | $100 | $200 | $350 | Working condition; price varies with wear and location |
| New old-stock TB240 | $400 | $500 | $650 | Availability is limited; confirm warranty and storage condition |
| Common repair allowance | $30 | $125 | $300 | Routine service through major engine or drive repairs |
What a working Troy-Bilt TB240 usually costs
The TB240 is a 21-inch self-propelled, gas-powered walk-behind mower. A used unit that starts readily, cuts evenly, and drives properly often lists for $150-$275. Mowers needing a tune-up or cosmetic work may be offered for $75-$150, while unusually clean machines can reach $300-$350.
A realistic target for a ready-to-mow used TB240 is about $200 before tax or delivery. Prices are asking-price estimates rather than guaranteed sale prices. New old stock can command $400-$650, but buyers should verify that the mower is actually unused and ask what warranty, if any, transfers.
Assumptions: U.S. private-party or small-dealer pricing, standard 21-inch TB240 configuration, and no major engine or drive defect.
How mower condition and included parts affect the price
A seller’s price reflects more than the model name. A running test, clean oil, sound wheels, and a working self-propel system support a higher quote. A dull or damaged blade, clogged deck, worn drive cable, or uncertain fuel system can justify a lower offer. Confirm the exact model and engine details on the mower’s identification label.
| Quote item | Typical amount | What it covers |
|---|---|---|
| Used mower purchase | $100-$350 | Complete mower; condition drives the range |
| Blade replacement | $20-$50 | Part only; sharpening may cost less |
| Basic tune-up | $60-$150 | Typical shop service, such as oil, plug, and air-filter work |
| Pickup or delivery | $0-$75 | Depends on distance and seller arrangement |
| Drive or engine repair | $100-$300+ | Diagnosis and parts can push a repair beyond mower value |
Ask for a cold start and a self-propel test before paying. A mower that starts only when warm may have a fuel or engine issue, and a mower that cuts but will not drive is not equivalent to a fully functioning TB240.
Which engine, deck, and drive problems change the quote?
Mechanical condition creates the biggest price swings. A blade or air-filter issue is usually a modest repair, but an engine that smokes, knocks, or will not stay running can require $150-$300 or more in shop work. A failed self-propel drive may add roughly $100-$250, depending on the failed part and labor. These are broad repair estimates, not TB240-specific guaranteed shop rates.
Deck rust matters when it affects strength rather than appearance. Surface rust may be manageable, but holes or severe corrosion can make replacement impractical. Check whether all four wheels adjust, the handle and controls are intact, and the mower bag or side-discharge parts are included; missing accessories can add cost or inconvenience.
Independent small-engine shops commonly charge about $75-$125 per hour, plus parts; a minimum diagnostic or service charge may apply.
When does repairing a TB240 beat buying another mower?
For a sound mower needing routine service, spending $60-$150 can be reasonable if the deck and drive are in good shape. A repair quote near $200-$300 deserves comparison with another working used mower, especially if the engine, transmission, and deck all show wear. Repair costs are separate from the purchase price, so include both when evaluating a project mower.
Comparable 21-inch walk-behind mowers from other brands may offer a wider selection of replacement parts or different drive features. A basic push mower can cost less than a self-propelled model, but it requires more effort on slopes or larger lawns. Compare condition, warranty, and serviceability rather than paying extra solely for the TB240 badge.
Set a combined purchase-and-repair ceiling before negotiating. For example, a $100 mower plus a $200 repair is a $300 purchase in practical terms, not a $100 bargain.
Why local availability shifts TB240 asking prices
The TB240 is an older model, so local supply can matter more than a national retail price. In areas with long mowing seasons and active used-equipment markets, working mowers may be easier to find and prices more competitive. In higher-cost metro areas or places with fewer listings, asking prices can run roughly 10%-20% above comparable rural listings. These differences are directional, not fixed regional rules.
Season also affects negotiations. Listings often increase during spring, when demand is strongest; late-season sellers may accept less, particularly for a mower that needs cleaning or service. A seller’s asking price may not include sales tax, a delivery fee, or a shop inspection, so compare the out-the-door total.
Three TB240 quotes show the cost of condition
| Example | Price details | Estimated total |
|---|---|---|
| Project mower | $100 purchase plus $125 tune-up and parts | $225 |
| Ready-to-use used mower | $200 purchase plus $25 pickup expense | $225 |
| Clean dealer unit | $325 purchase plus $35 local delivery | $360 |
These examples illustrate how condition and transport change the real price; they are not quotes for a particular seller. Before buying, request a written list of included accessories, known defects, and any service performed.
How to lower the TB240 purchase and upkeep bill
Compare at least a few local listings and ask sellers to demonstrate starting, cutting, and self-propel operation. Inspect the mower before arranging delivery, and price missing parts before making an offer. A small discount may not compensate for a questionable engine or damaged deck.
Keep routine maintenance in the budget: fresh oil, a clean air filter, a sharp blade, and proper winter fuel storage can help avoid preventable service calls. If the mower needs only ordinary maintenance, choose that over a major upgrade or cosmetic restoration. Base the offer on verified operating condition and expected repair cost, not the original retail price.
