A used John Deere JS28 typically costs $75-$350 in the U.S., with many running mowers listed near $175-$250. The JS28 is an older 21-inch walk-behind mower, so price depends mainly on condition, engine performance, included bag or accessories, and local demand; new-stock pricing is generally unavailable.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Used, running JS28 | $75 | $200 | $350 | Price varies with condition and local market |
| Non-running or repair project | $25 | $75 | $150 | Engine or drive issue may increase repair cost |
| Basic tune-up | $60 | $110 | $180 | Typical shop service; parts and labor vary |
| Replacement mower | $250 | $450 | $700 | New walk-behind models, depending on features |
What a used 21-inch John Deere JS28 usually costs
Most buyers should budget $150-$275 for a complete, running JS28 with a sound deck, working controls, and a usable grass bag. A clean example with recent service may reach $300-$350, while a mower needing a carburetor, cable, or blade work often sells for $75-$150. Because the model is older, listings and prices differ substantially by area.
The JS28 is a walk-behind mower with a 21-inch cutting deck. It is not typically priced like a current new John Deere mower, and condition matters more than the original retail price. Assumptions: standard residential configuration, local pickup, functioning engine, and no major deck damage.
How engine, deck, and parts shape the asking price
Private-party prices usually reflect the mower itself and whatever working equipment comes with it. A missing bag or worn blade can reduce value, while a tested engine and complete controls help support a higher asking price. Delivery is often separate from the listing price.
| Quote item | Typical range | What changes the amount |
|---|---|---|
| Used mower | $75-$350 | Starts easily, cuts evenly, deck condition |
| Grass bag or chute part | $20-$100 | Used, aftermarket, or model-specific replacement |
| Blade and installation | $25-$65 | Blade type and shop minimum charge |
| Engine tune-up parts | $20-$60 | Filter, spark plug, oil, and fuel-system needs |
| Shop labor | $75-$125 per hour | Local rates and diagnostic minimum |
Parts availability and labor can outweigh the mower’s resale value. Confirm the exact model and engine details before ordering components, since older equipment may require a compatible substitute.
Why a 21-inch deck and engine condition change value
Engine starting behavior is a major price divider. A JS28 that starts cold, runs without surging, and keeps running under load is worth more than one that starts only after repeated pulls. A shop may charge $30-$75 for diagnosis or a minimum inspection, even if the final repair is small.
Inspect the steel deck for deep rust, cracks, or holes, especially near the blade and wheel mounts. Damage that affects blade safety or deck strength can make the mower unsuitable for use. Also test the height adjustment across its range and check whether the blade spins freely with the engine off.
A missing accessory is usually a smaller concern than a damaged deck or failing engine. A bag or chute may be replaceable for tens of dollars, while an engine repair or replacement can exceed the value of a typical used JS28. Confirm whether the mower is self-propelled and test that drive system if the specific unit has it.
Is repairing a JS28 cheaper than buying another mower?
A tune-up involving fresh oil, a spark plug, and an air filter may cost $60-$140 at a repair shop. Carburetor cleaning or replacement can bring a bill to roughly $100-$220, depending on diagnosis, parts, and labor. Blade sharpening or replacement is generally less expensive, often $25-$65 installed.
For a mower bought for $150-$200, a repair quote above $200 deserves comparison with another used mower or a basic new model. Set a repair ceiling before authorizing work. If the deck is damaged, the engine needs major work, or several parts are failing together, replacing the unit may be more economical.
How local demand shifts JS28 prices across the U.S.
Prices can run 10%-25% higher in dense suburbs or areas where used lawn equipment sells quickly, particularly during spring. Rural listings may be cheaper, but buyers can face longer pickup distances or fewer comparable machines. In warm-weather states, demand can remain steadier through more of the year.
Transport can add $20-$75 if a seller delivers locally, or more for a longer trip. Compare several listings within a practical driving radius and account for the mower’s condition rather than treating the lowest advertised price as the best deal.
Three realistic JS28 price examples
- Project mower: $60 purchase price, plus $90 for a carburetor service and basic parts, totals about $150 before transport. This assumes the deck and engine are otherwise sound.
- Ready-to-mow private sale: $225 for a running mower with bag and tested controls, plus $35 for a blade, totals about $260.
- Shop-serviced example: $275 purchase price, plus $120 for a tune-up and inspection, totals about $395. At this amount, compare current replacement options before buying.
Which checks can keep a used JS28 price down?
Ask the seller to start the mower from cold and demonstrate a complete cut, blade engagement, and any drive function fitted to that unit. Check for oil leaks, excessive vibration, smoke, damaged wheels, and missing hardware. A short test can reveal problems that are difficult to assess from photos.
Use repair findings to negotiate, not to overlook safety defects. Price a missing bag or worn blade before agreeing on a total, and request the model or serial information to verify part fit. Buying off-season may improve bargaining room, while a spring purchase often involves more competition.
Compare the final price—including parts, shop fees, and pickup—with a similar used mower and a basic new walk-behind. A JS28 with a sound deck and dependable engine can make sense at a modest price; a high repair bill can quickly erase the savings.
