A new STIHL FS 91 R typically costs about $350-$430 before tax, with an average price near $390 at U.S. dealers. The final amount depends on dealer pricing, included cutting equipment, local taxes, delivery, and whether the machine is new, used, or bundled with accessories.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| New FS 91 R | $350 | $390 | $430 | Before tax; dealer prices vary |
| Used FS 91 R | $150 | $240 | $325 | Condition and service history matter |
| Basic ready-to-work purchase | $375 | $425 | $490 | May include tax and basic accessories |
What a new STIHL FS 91 R usually costs
Budget roughly $350-$430 for the trimmer itself, before sales tax and optional gear. The FS 91 R is a gas-powered professional trimmer with a 28.4 cc engine and loop handle. Dealer listings and local inventory can put the same model at different prices; STIHL products are commonly sold through authorized dealers rather than one uniform national checkout price.
At the low end, the price may reflect a dealer promotion or a bare machine with standard equipment. A typical transaction is about $390 before tax. A higher quote may reflect local pricing, delivery, or included accessories rather than a different engine or model. Assumptions: new machine, standard cutting equipment, no extended service plan, and ordinary U.S. dealer availability.
Which dealer quote items add to the trimmer price
Compare the machine price with the full out-the-door quote. The line items below are common budget estimates, not mandatory charges; dealers may include some equipment or setup in the listed price.
| Quote item | Typical range | What changes the charge | Budget note |
|---|---|---|---|
| FS 91 R machine | $350-$430 | Dealer and local inventory | Largest expense |
| Line head or cutting accessory | $0-$70 | Included equipment and accessory type | Check what comes in the box |
| Setup or pre-delivery service | $0-$40 | Dealer policy and assembly work | May be included |
| Delivery or local transport | $0-$50 | Distance and dealer service | Pickup may avoid the fee |
| Sales tax | About 0%-10% | State and local tax rules | Applied to taxable items |
Ask whether the quote includes setup, cutting equipment, and tax before comparing dealers. A $390 advertised price can become roughly $415-$455 after tax and small add-ons, depending on location and what is included.
How engine size, cutting gear, and condition affect price
The 28.4 cc engine and professional-duty design help position the FS 91 R above many homeowner trimmers. A larger accessory package can add cost, but changing from a standard line head to a blade or specialty attachment may require compatible parts and dealer confirmation.
Used-machine condition creates a wider spread. A clean, recently serviced FS 91 R with a functioning engine may sell for $250-$325; a machine with worn line-feed parts, hard starting, or unknown maintenance may be closer to $150-$225. A repair estimate can erase the apparent savings: small service jobs may run $50-$150, while carburetor or engine work can cost more.
Inspect the starter, fuel system, shaft, head, and service history before treating a used price as a bargain. Replacement parts and labor depend on the failed component and local shop rates.
When does a used FS 91 R beat a new one
A used unit around $200-$250 can make sense when it starts easily, idles steadily, accelerates without hesitation, and includes usable cutting equipment. A buyer should test it cold, inspect for fuel leaks and shaft damage, and ask when the air filter, spark plug, and fuel lines were last serviced.
Compare the used price plus likely repairs against a new dealer quote. For example, a $220 used trimmer needing $100 in service totals $320 before replacement parts or tax. If a new machine is available near $350-$390, the smaller remaining price gap may favor new equipment with dealer support and a clearer warranty path.
How much dealer setup and service can add
Dealers may sell the FS 91 R assembled and ready to use, or list setup separately. If charged, setup is often around $20-$40 for inspection, assembly checks, and initial adjustment. Local labor rates for repair work commonly fall near $75-$125 per hour, though shops may use flat-rate charges or minimum diagnostic fees.
Routine setup should not be confused with a repair or extended service plan. Ask for the exact work and fee in writing, especially if the machine is being delivered or prepared with a different cutting attachment. A service package is worth comparing by covered tasks and duration, not just its headline price.
Why FS 91 R prices differ by region and season
Dealer prices can run about 5%-10% above or below a typical local quote due to competition, inventory, and operating costs. Urban areas may add delivery or service charges, while rural buyers may face longer travel or fewer dealers. Sales tax can also make a noticeable difference in the final amount.
Spring demand can limit discounts as landscaping work ramps up. Late-season inventory or a dealer promotion may improve the price, but availability varies and a specific model may not be discounted. Calling several nearby authorized dealers can reveal whether a quote is unusually high for the area.
Ways to lower the FS 91 R purchase total
Compare complete quotes and avoid buying accessories that the job does not require. Request the machine price, included cutting head, setup charge, delivery, and tax as separate figures. Then compare the same configuration at two or three dealers rather than comparing a bare price with a bundled offer.
Pickup can avoid delivery fees, and using included cutting equipment can postpone accessory spending. For occasional trimming, a lighter residential model may cost less; for frequent or demanding work, compare its durability and expected repair needs before choosing by purchase price alone. A used FS 91 R is most attractive when inspection confirms good condition and the price leaves room for service.
Do not assume a bundle saves money unless each extra item is useful and priced separately. Gloves, eye protection, fuel containers, and maintenance supplies can be purchased later if needed, while an unnecessary attachment adds to the initial bill. Confirm warranty coverage and dealer service terms before paying more for a package.
