The Stihl KM 131 R price is typically about $500-$570 for a new powerhead, when available, before sales tax and attachments. Final spending depends on whether the unit is new or used, which KombiSystem attachments are included, and local dealer charges.

| New KM 131 R powerhead | $499 | $535 | $570 | Powerhead only; availability varies |
| Used powerhead | $250 | $350 | $450 | Condition and service history matter |
| Powerhead with one attachment | $600 | $750 | $900 | Attachment type changes the package price |
| Tax and dealer setup | $25 | $55 | $100 | Varies by location and seller |
Estimates are approximate U.S. retail ranges; listings, inventory, tax, and included accessories vary by dealer.
What a Stihl KM 131 R Typically Costs
The KM 131 R is a gas KombiSystem powerhead, not a complete tool for every task. New units have commonly been priced around $499-$570 before tax; the average buyer budget for the bare powerhead is about $535. Because product availability can vary, some dealers may have remaining inventory while others offer a successor or a different model instead.
Plan on roughly $525-$625 for a new powerhead after typical tax and basic dealer charges, before adding a working attachment. A package with an attachment often reaches $600-$900. Local sales tax can add roughly 5%-10%, and freight or special-order charges may apply. Assumptions: standard U.S. retail purchase, powerhead only, ordinary access to a local dealer.
Powerhead, Attachment, and Dealer Charges in a Quote
Request an itemized quote that separates the engine unit from the tool end. The KM 131 R’s attachment compatibility is useful for switching jobs, but each attachment is generally an additional purchase. Prices below are planning ranges, not guaranteed dealer quotes.
| Quote item | Typical price | What changes the charge | Pricing basis |
|---|---|---|---|
| KM 131 R powerhead | $499-$570 | Inventory and seller | Per unit |
| Brushcutter attachment | $150-$250 | Cutting head and configuration | Per attachment |
| Hedge trimmer attachment | $200-$350 | Blade type and reach | Per attachment |
| Edger attachment | $150-$230 | Model and blade setup | Per attachment |
| Dealer setup or inspection | $0-$60 | Included service or requested work | Per unit |
| Sales tax and delivery | $25-$100 | Tax rate and delivery distance | Per purchase |
Attachments can add more to the checkout total than setup fees do. Ask whether the listed price includes a harness, cutting head, guard, or other required operating parts; packages differ, and accessories should not be assumed included.
Engine Size and Attachment Choice Move the Total
The KM 131 R uses a 36.3 cc engine, and the powerhead price alone does not reflect the cost of outfitting it for a specific task. A basic edger or brushcutter attachment may add about $150-$250, while a hedge trimmer attachment can be $200-$350. Adding two attachments can push a typical new setup toward $800-$1,100 before tax, depending on the models selected.
Condition is another major variable. A used powerhead with a cold-start problem or worn clutch may need service that erases the initial savings. Ask the seller to demonstrate a cold start and sustained operation, and check for fuel leaks, damaged controls, and signs of poor maintenance.
Compare the same attachment configuration and included accessories, not just the powerhead sticker price. Assumptions: common attachment ranges and separate purchase of the powerhead; dealer and regional pricing may differ.
Ways to Keep a KM 131 R Purchase Within Budget
Buy only the attachment needed for the immediate job, then add other tools only when they will be used regularly. If the seller offers a complete package, compare its itemized value against buying the powerhead and attachment separately. Avoid paying for duplicate heads, guards, or harnesses already included with existing compatible equipment.
For a used unit, set aside money for a tune-up rather than spending the entire budget on the purchase. A dealer inspection or repair may run about $75-$150 depending on the work. At a typical small-engine shop rate of $75-$125 per hour, even a short diagnostic or repair visit can affect the value of a low-priced used listing.
Choose based on total usable-tool cost, including the right attachment and likely service, rather than the lowest powerhead price. Get written quotes from nearby authorized dealers and confirm any warranty terms and return conditions.
Used KM 131 R Prices Depend on Condition
Used powerheads commonly list around $250-$450, with exceptionally clean or lightly used units sometimes priced near the cost of remaining new inventory. A lower price is more reasonable when the unit has visible wear, no recent service, or limited accessories; it is not automatically a bargain if it needs carburetor, clutch, or fuel-system work.
Check that the seller can show the machine running with an attachment fitted. Ask about age, repairs, storage, and whether the serial number and operating manual are available. A used package with one compatible attachment might fall around $400-$650, depending on attachment condition and local demand.
Use a repair allowance of $75-$150 when comparing an uninspected used unit with a dealer-checked machine. A purchase with no clear starting demonstration should be priced with additional repair risk in mind.
Dealer Setup and Delivery Can Change the Checkout Total
Many hand-held power equipment purchases require little assembly, but some dealers include inspection, fueling, or operational checks in the advertised price while others list setup separately. That fee may be $0-$60. Delivery, if needed, can add roughly $25-$100 or more depending on distance and seller policy.
Dealer labor can also matter when a buyer requests installation of an attachment or diagnosis of a used unit. Ask whether the quote includes a demonstration and what the warranty covers. Taxes are charged according to local rules and may apply to the equipment and some fees.
Confirm the out-the-door amount in writing, including setup, delivery, tax, and attachment installation. Assumptions: ordinary local purchase; special ordering and long-distance delivery can cost more.
KM 131 R Versus Buying Separate Lawn Tools
The KombiSystem can reduce the need to store several complete engines when multiple compatible attachments are used. Its financial advantage depends on how often each attachment is needed: a powerhead plus two attachments may cost roughly $800-$1,100, while buying only one dedicated tool can be cheaper for a single recurring task.
Before choosing, compare the package with a standalone trimmer, edger, or hedge trimmer that includes its own engine. A standalone tool may be easier to price and maintain, while the KM 131 R system shares one powerhead across compatible tools. Confirm fit before buying used attachments, since compatibility should not be assumed across every model or generation.
For occasional use of one tool, compare the complete package price; for frequent use across multiple tasks, price each attachment against a separate machine.
