A used STIHL TS 420 cut-off saw commonly sells for about $300-$700, with many serviceable examples near $450. Age, starting and cutting condition, included 14-inch blade, and local demand can shift the price; repairs or missing parts may make a low asking price costly.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Used TS 420 saw | $300 | $450 | $700 | Running saw, condition and accessories vary |
| Nonrunning or repair-needed saw | $100 | $225 | $350 | Price depends on diagnosis and parts |
| Used saw with case and extras | $400 | $550 | $800 | Extras add value only if usable |
| Replacement 14-inch blade | $40 | $90 | $180 | Blade type and cutting material affect price |
Used STIHL TS 420 prices by saw condition
A clean, tested TS 420 that starts easily, idles steadily, and cuts without bogging typically falls around $400-$600. Examples in especially good condition with a usable blade, intact guard, and documented service may reach $600-$700. An older saw with uncertain history or visible wear is more often $300-$400.
Nonrunning units can be listed from roughly $100-$350, but the purchase makes sense only if the engine and major assemblies are repairable. For most buyers, a tested saw near $450 is a more useful comparison than the lowest listing price.
Assumptions: U.S. private-party pricing, standard 14-inch configuration, ordinary wear, and no major engine defect; dealer prices and local availability differ.
Engine repairs, blade, and guard costs in a used-saw quote
When evaluating a used TS 420, price the likely repairs separately from the seller’s asking price. A worn blade is a routine expense, while poor compression, fuel-system trouble, or a damaged guard can change the value substantially. Parts availability and repair labor vary, so a shop diagnosis is useful when the saw fails a basic test.
| Cost item | Typical price | What changes the charge |
|---|---|---|
| 14-inch abrasive blade | $40-$90 each | General-purpose versus specialty cutting |
| Diamond blade | $90-$180 each | Blade grade and intended material |
| Air filter and tune-up items | $20-$70 | Parts condition and service scope |
| Shop diagnostic or inspection | $40-$100 | Shop policy and whether repair follows |
| Fuel-system or starter repair | $100-$300 | Parts needed and technician time |
A worn blade is inexpensive to replace; engine or clutch symptoms deserve a much larger price adjustment. Repair estimates are approximate and should be confirmed with a local small-engine shop.
How blade size, compression, and age change value
The TS 420 is designed around a 14-inch cutting wheel, and a saw missing its correct guard or wheel hardware needs closer inspection. A blade with less than about 25% of its usable cutting depth remaining may need replacement soon. Ask whether the saw has been used mainly for concrete, masonry, or metal because blade wear and dust exposure differ.
Compression readings below roughly 100 psi can indicate serious wear on a two-stroke engine, although test method and engine condition matter; a mechanic should interpret the result. Difficult cold starts, unstable idle, or loss of power under load are also warning signs. Condition and verified operation matter more than a seller’s estimate of age or hours.
Three realistic TS 420 used-saw price examples
A basic private-party example might be listed for $350. If it starts and runs but needs a $60 blade and $40 in filter or tune-up supplies, the practical outlay becomes about $450 before tax or transport.
A tested saw in good working order might cost $475, with a usable blade and guard included. A shop inspection at $60 brings the initial spend to about $535, but reduces uncertainty compared with an untested purchase.
A clean unit with case and accessories might be priced at $650. If its blade is near the end of its life, add roughly $90-$180 for a suitable replacement, bringing the total to $740-$830. Compare the ready-to-cut cost, not just the seller’s number.
Used TS 420 versus a newer cut-off saw
A used TS 420 at $400-$600 can be economical when it is tested and parts are in good shape. A newer comparable gasoline cut-off saw may cost roughly $900-$1,500, depending on brand, model, and dealer. New equipment costs more upfront but may include warranty coverage and a known service history; warranty terms on used private-party sales are usually limited or absent.
For occasional work, a sound used saw may justify the savings. For frequent commercial cutting, consider whether downtime, repairs, and blade costs offset the lower purchase price. Compare total ownership exposure rather than assuming an older saw is automatically the cheaper option.
Where U.S. location changes the asking price
Prices can run about 10%-20% higher in dense metro areas with active construction demand than in less populated markets, while rural listings may have fewer choices and require travel. Regional differences are not fixed: seasonal construction activity, dealer access, and the number of used saws nearby can matter more than state lines.
Budget for pickup or shipping before comparing distant listings. Freight for a heavy, fuel-powered tool can add about $50-$150, and sellers or carriers may require the fuel system to be drained. A local tested saw can be a better value than a cheaper listing with transport and inspection costs.
What labor time and shop service add to the bill
A straightforward inspection may take about 30-60 minutes, while troubleshooting a starting or cutting problem can take 1-2 hours or longer. Small-engine labor commonly runs about $75-$125 per hour, plus parts. A basic tune-up could total $100-$250; a more involved repair may exceed $300 depending on the fault.
Ask whether the shop charges a separate diagnostic fee and whether it is credited toward approved repairs. Get the diagnosis and a written estimate before authorizing work on a low-priced saw.
How to negotiate a lower TS 420 purchase price
Request a cold start, steady idle, and brief cut under load rather than accepting a warm engine demonstration alone. Check the starter, throttle lock, stop switch, guard, air-filter cover, and visible fuel leaks. If the seller cannot demonstrate operation, value the unit as untested and leave room for diagnosis and repairs.
Use documented needs to negotiate: subtract the local price of a blade, missing guard hardware, or shop inspection from a comparable running-saw price. Avoid paying extra for accessories that are worn or incompatible, and compare at least two local quotes. Set a maximum based on purchase price plus immediate repairs, not on the seller’s original asking price.
