A new STIHL FC 91 edger typically costs about $350-$450 before tax, with an average price near $400 for the power unit at a U.S. dealer. The final quote depends on local pricing, included accessories, setup, and whether the machine is new, used, or sold with additional equipment.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| New FC 91 power unit | $350 | $400 | $450 | Before sales tax; confirm included blade and guard |
| Typical new purchase with tax | $370 | $430 | $490 | Tax varies by state and local rate |
| Used FC 91 | $150 | $250 | $350 | Condition, age, and service history matter |
| Replacement edger blade | $15 | $25 | $40 | Blade style and dealer pricing affect cost |
What a new STIHL FC 91 usually costs
For a new machine, budget $350-$450 before tax, or roughly $400 as a planning figure. The FC 91 is a dedicated gas-powered edger with a 28.4 cc engine; the price is for the machine, not a complete landscaping crew or recurring service. Ask the dealer to confirm the current local price and exactly what is included.
Assumptions: new equipment, ordinary U.S. dealer pricing, standard blade and guard if included, and no delivery charge. Prices can differ because STIHL equipment is sold through independent dealers, and promotions or inventory can change the amount on the quote.
Which FC 91 parts and dealer services appear on the quote
A quote may combine the edger with setup or optional purchases. Separate the machine price from accessories and service charges to compare offers accurately.
| Quote item | Typical price | What can change it |
|---|---|---|
| FC 91 power unit | $350-$450 | Dealer, location, promotion, and stock |
| Replacement blade | $15-$40 | Blade dimensions and type |
| Fuel and oil for initial use | $10-$25 | Fuel quantity and product choice |
| Setup or pre-delivery service | $0-$40 | Dealer policy and work performed |
| Delivery, if offered | $0-$50 | Distance and dealer delivery minimum |
| Sales tax | About 0%-11% | State and local tax jurisdiction |
How 28.4 cc power and blade condition affect price
The FC 91’s 28.4 cc engine and dedicated edging design make it different from an inexpensive consumer trimmer attachment. Buyers should compare it with other dedicated edgers that offer similar power and service access, rather than comparing only the lowest-cost attachment price. Engine class and machine condition are major used-price drivers.
For used equipment, a running unit with a sound gearbox, straight shaft, working throttle, and intact blade guard may fall around $225-$350. A machine with difficult starting, a worn blade, or uncertain maintenance may be closer to $150-$225, but repairs can erase the apparent savings. Request a cold start and inspect for leaks, unusual vibration, and damaged controls.
Why dealer location changes the FC 91 price
Dealer pricing is not uniform nationwide. As a rough budgeting adjustment, large metro areas and higher-cost coastal markets may run about 5%-15% above a lower-cost rural or inland quote; rural dealers may instead add delivery or have fewer units in stock. These are comparison allowances, not fixed regional tariffs.
Compare the same machine and included items, not just the advertised number. A dealer quote with setup and a blade can be better value than a lower machine-only price once those items are added. State tax also changes the checkout total: on a $400 purchase, a 6%-10% rate adds $24-$40.
What blade, fuel, and repair expenses can add
Normal ownership expenses are separate from the purchase price. A replacement blade may cost $15-$40, while fuel and two-cycle oil for initial use commonly add $10-$25. Routine service pricing depends on the dealer and work requested; a basic inspection or tune-up may range from about $50-$120, with parts or significant repairs extra.
Ask what a service quote includes before approving work. A sharpening or blade replacement is not the same as carburetor, ignition, or gearbox repair. For a used FC 91, a $50-$120 service allowance is prudent if the seller cannot document recent maintenance.
Three FC 91 purchase examples with realistic totals
These examples show how accessories, tax, and condition change the out-the-door budget. Actual dealer prices and local tax rates vary.
| Purchase scenario | Before tax | Estimated total | Assumptions |
|---|---|---|---|
| New machine, low quote | $350 | $371 | 6% tax; no delivery or extras |
| New machine, typical setup | $425 | $459 | $400 machine, $25 blade, 8% tax |
| Used machine with service allowance | $320 | $345 | $250 unit, $70 service allowance; before tax estimate |
The used example is a planning estimate rather than a dealer package. If service is not needed, the purchase may cost less; if repairs are required, the final expense could exceed the estimate.
Is a used FC 91 cheaper than a new edger
A used FC 91 at $150-$350 can reduce the initial outlay, but it has no new-equipment condition and may require parts or service. A new unit around $350-$450 costs more upfront and lets the buyer check dealer support and warranty terms directly. Compare total cost after inspection and likely repairs.
A basic consumer edger or compatible attachment may cost less, often roughly $100-$250 depending on type, but it may not provide the FC 91’s dedicated machine format or comparable durability. Confirm compatibility before buying an attachment; not every STIHL power unit accepts every tool.
How to keep an FC 91 quote within budget
Request an itemized quote showing the machine, blade, setup, delivery, and tax separately. Compare at least two authorized local dealers using the same model and included equipment, and ask whether setup is already included rather than paying twice for preparation.
Control add-ons and condition-related risk before negotiating the headline price. Buy only needed blades or fuel supplies, inspect a used unit before purchase, and avoid assuming a lower sticker price includes service or a warranty. If the FC 91 is for occasional edging, compare the purchase price with a lower-cost attachment or hiring the task out before committing.
