A used Stihl FS 85 typically sells for about $100-$250, with a well-maintained, running unit averaging around $175 before tax or shipping. The Stihl FS 85 used price depends most on starting condition, engine compression, included cutting attachments, and whether the machine is a straight-shaft trimmer or another FS 85 configuration.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Running used FS 85 | $100 | $175 | $250 | Typical private-sale range; condition and attachments vary |
| Clean, serviced example | $175 | $250 | $350 | Higher asking prices require strong condition and proof of service |
| Nonrunning project unit | $25 | $65 | $110 | Price depends on completeness and diagnosis |
| Common repair allowance | $30 | $90 | $220 | Parts-only through shop repair, depending on fault |
What a running Stihl FS 85 costs used
Most buyers should budget $100-$250 for a complete FS 85 that starts, idles, and accelerates reliably. Around $150-$200 is a reasonable target for an older machine with normal cosmetic wear, a usable guard, and a functioning head. A clean example with recent maintenance may reach $250-$350, particularly when it includes a harness, metal blade, or useful accessories.
For a typical private-party purchase, about $175 is a practical midpoint, not a guarantee of mechanical condition. A nonrunning or incomplete unit may be worth only $25-$110 as a repair project or parts source. Dealer or equipment-reseller prices can be higher because of inspection, service, and limited warranty coverage; check what those charges actually include.
Assumptions: U.S. private-sale pricing, standard used condition, complete powerhead, and no major engine or shaft damage. Local listings and seasonal demand can shift these ranges.
How carburetor, labor, and attachments shape the quote
A used trimmer’s price is only part of its cost if it needs service. A buyer may handle simple maintenance at home, while a shop charges for diagnosis and repair. Labor rates often fall around $75-$125 per hour, and a shop may apply a minimum diagnostic or service charge of $25-$60.
| Quote component | Typical price | What it covers | Cost note |
|---|---|---|---|
| Carburetor cleaning or rebuild kit | $15-$50 | Parts for fuel-system service | Labor may add $50-$125 |
| Spark plug and fuel filter | $8-$25 | Basic tune-up parts | Often replaced during service |
| Starter rope or recoil repair | $10-$45 | Rope, spring, or assembly parts | Shop total can reach $60-$150 |
| Trimmer head or blade | $20-$80 | Replacement cutting attachment | Compatibility and condition matter |
| Shop inspection and labor | $25-$125 | Diagnostic minimum or roughly one hour | Ask whether the fee is credited to repairs |
One hour of shop labor at $75-$125 can change a bargain purchase into a much more expensive one. A complete working machine is usually more predictable than a low-priced unit with unknown fuel-system or ignition trouble.
Which engine and shaft problems move the price most?
Starting difficulty alone does not prove that an FS 85 needs a major repair; stale fuel, a clogged filter, or a dirty carburetor may be inexpensive to address. However, weak compression, damaged cylinder components, a failing ignition system, or a bent drive shaft can make repair uneconomical. Ask to see a cold start, then check that the engine stays running and responds to throttle.
Missing parts also affect value. A missing guard, handle, harness, or cutting head may require roughly $20-$100 or more to replace, depending on the part and whether it is new or used. A damaged shaft or cracked housing deserves closer inspection than ordinary scuffs. If a seller cannot demonstrate operation, price the unit as a project rather than paying the running-machine average.
Condition thresholds matter more than a seller’s description: a cold-start demonstration and a mechanic’s compression check can justify a different offer. Request the model identification and confirm that any included attachments fit the specific configuration.
How long does an FS 85 inspection or repair take?
A brief buyer inspection may take 10-15 minutes, including a cold start, throttle test, and check of the shaft, controls, and cutting attachment. A basic shop tune-up can take about 30-60 minutes of billed labor, while carburetor troubleshooting or starter repair may take 1-2 labor hours. Parts availability and a shop’s workload can extend the time the machine is unavailable.
Before authorizing work, ask for the diagnostic charge, hourly rate, and an approval limit. A $50 repair estimate for filters or a plug has a different value than a $50 estimate that excludes labor, carburetor parts, or additional faults. Get the complete repair total in writing before comparing it with the price of another running trimmer.
Three used FS 85 purchase totals to compare
A working machine at a fair asking price can cost less overall than a cheaper project once parts and labor are added. These examples exclude sales tax and assume local pickup.
| Buying scenario | Machine | Added expense | Estimated total |
|---|---|---|---|
| Running private-sale unit | $150 | $20 for plug and fresh fuel | $170 |
| Used trimmer needing service | $100 | $40 parts plus 1 hour labor at $90 | $230 |
| Clean, equipped example | $275 | $0 immediate repair assumed | $275 |
These examples assume the machine is complete and exclude major engine, shaft, or electrical repairs. The $100 project is not automatically the lowest-cost option if a shop diagnosis reveals additional work.
When a repair makes more sense than another used trimmer
Compare repair cost with the local price of another tested, running unit, not just with the cheapest listing. Spending $30-$80 on routine parts can be sensible when the engine and shaft are sound. A repair quote above $150-$200 deserves a closer comparison, especially if it covers a major engine issue or several missing components.
New gas trimmers vary widely by brand, power, and warranty, but entry-level models commonly cost several hundred dollars. That makes a sound used FS 85 attractive to some buyers, but the older machine may need more upkeep and may have limited parts availability for particular components. Set a repair ceiling before purchase and walk away if the quote exceeds the value of a comparable working unit.
Why FS 85 asking prices vary by location
Local supply, shipping, and the length of the yard-work season can affect asking prices. In high-demand metro areas, a ready-to-use unit may list about 10%-20% above a similar rural private-sale machine, while rural buyers may face fewer nearby choices and more travel. These are planning ranges, not fixed regional price rules; actual listings vary by condition and included equipment.
Online shipping can add roughly $40-$100 or more for a bulky used tool, and shipping does not confirm its mechanical condition. Local pickup allows a start-up test and reduces delivery expense. Compare completed, local listings with similar attachments rather than comparing an inspected unit with an untested shipped listing.
How to negotiate a lower FS 85 price without guessing
Ask the seller to start the engine cold, demonstrate acceleration, and identify recent service. Use documented issues—such as a missing head, worn starter rope, or failed cold start—to support a specific deduction based on replacement parts or a repair estimate. Avoid assuming a carburetor cleaning will solve every starting problem.
Check whether the price includes a guard, harness, blade, or extra head before treating accessories as free value. Buying during a slower season may improve negotiation, though condition should matter more than timing. Choose the lowest verified total for a complete, functioning trimmer, not simply the lowest advertised price. If the seller will not permit a basic operating test, leave room in the budget for inspection or choose a machine with a clearer service history.
