A new Stihl MS 661 C-M typically costs about $1,450-$1,750 for the powerhead, with a complete saw-and-bar package often reaching $1,600-$1,950. The final price depends on dealer pricing, bar length, included chain, location, and whether the saw is new or used.
Budget separately for protective equipment, fuel, and replacement chains; those expenses are not always included in the advertised saw price.

What a new MS 661 C-M costs at U.S. dealers
The MS 661 C-M is a professional 91.1 cc gas chainsaw intended for demanding felling and bucking work. A practical budget is $1,450-$1,750 for the powerhead alone, before sales tax. A ready-to-cut configuration with bar and chain is commonly around $1,600-$1,950, depending on bar length and dealer package.
For a standard new saw with a 25-inch bar, about $1,700-$1,850 before tax is a reasonable planning range. A shorter bar may lower the package price, while a longer bar, extra chains, or dealer setup can raise it. Local authorized dealers set their own retail prices, so an online advertised price may not match a nearby quote.
Prices also depend on what the seller means by “powerhead.” Some listings show the engine unit without a bar and chain; others display a configured saw. Confirm whether the quoted amount includes the guide bar, one chain, scabbard, manuals, and assembly. Sales tax is additional and varies by location.
Assumptions: New MS 661 C-M, ordinary U.S. dealer availability, standard configuration, and no unusual delivery or financing fees.
How the powerhead, bar, and chain shape the quote
A dealer quote can combine the powerhead with cutting equipment and setup. These are representative price contributions, not guaranteed standalone list prices; package discounts and dealer inventory can change the final total.
| Quote component | Typical price | What changes the amount | Buyer check |
|---|---|---|---|
| MS 661 C-M powerhead | $1,450-$1,750 | Dealer, availability, and configuration | Ask whether this is powerhead-only pricing |
| Bar and one chain | $100-$250 | Bar length, chain pitch, and bar type | Verify compatibility and included chain |
| Additional chain | $35-$75 each | Length, gauge, pitch, and chain style | Match the chain to the bar markings |
| Dealer setup or inspection | $0-$100 | Dealer policy and service requested | Ask what assembly or checks are included |
| Sales tax | About 0%-10%+ | State and local tax rules | Compare the out-the-door total |
Bar and chain pricing is especially easy to misread: a longer bar can cost more, but the chain must also match the saw’s bar length, pitch, and gauge. Some dealer packages include a selected bar and chain in the displayed price; others price the powerhead separately.
Compare complete, tax-inclusive quotes with the same bar length and included accessories. A lower powerhead figure may not be the lower cost once cutting equipment and setup are added.
Bar length, chain setup, and displacement change the price
The 661 is a high-displacement professional saw, but the bar configuration still affects the package price and operating suitability. A 20- or 25-inch setup may cost less than a 28- or 36-inch setup, while extra-long bars and compatible chains can add expense. The correct choice depends on wood diameter, cutting method, and the manufacturer’s recommendations.
For planning, allow roughly $100-$250 for a supplied bar and chain combination, with specialty or longer equipment potentially costing more. A second chain generally adds about $35-$75. A buyer replacing an existing saw should check whether a current bar and chain are compatible rather than assuming they will transfer.
Engine configuration matters too. The MS 661 C-M includes STIHL M-Tronic electronic engine management; listings for different 661 variants or older versions may not describe identical equipment. Check the exact model designation, serial-age information where available, emissions configuration, and warranty terms before paying a premium for a specific listing.
At bar lengths of 28 inches and above, verify both the price and the intended cutting application. A longer setup can require a larger budget for bar, chain, sharpening, and maintenance, and it is not automatically the best choice for every user.
Three realistic MS 661 C-M purchase budgets
These examples show how configuration and condition change the total. They are estimates before sales tax unless stated, and actual quotes depend on dealer pricing and local inventory.
| Buying scenario | Configuration | Estimated total | Cost context |
|---|---|---|---|
| Powerhead purchase | New saw, no bar or chain | $1,450-$1,750 | Suitable only when cutting equipment is purchased separately |
| Standard new setup | New saw, 25-inch bar, one chain | $1,600-$1,900 | Typical ready-to-cut dealer package |
| Used working saw | Used saw, bar and chain, condition verified | $700-$1,350 | Price depends heavily on wear and service records |
For a standard new setup, adding a spare chain, basic fuel and bar oil, and protective equipment can bring the initial outlay to roughly $1,850-$2,500. A user who already owns suitable PPE or compatible cutting equipment may spend less, while premium protective gear can push the total higher.
Used pricing should be judged against the saw’s repair needs, not just its asking price. A worn bar, damaged chain, hard starting, oiling problems, or engine damage can erase the apparent savings quickly.
Used 661 prices depend on hours and service condition
Used MS 661 C-M saws commonly list around $700-$1,350, with unusually clean, recently serviced examples or complete packages sometimes priced above that range. Older, heavily used, or incomplete saws can fall below it. Since seller claims about hours may be difficult to verify, condition and service evidence matter more than a stated hour count alone.
Before buying, inspect the starter and controls, chain brake, clutch cover, sprocket, bar rails, air filter, and visible fasteners. If permitted, request a cold start and a warm restart, and check that the saw oils the chain. A compression test by a qualified shop may help assess engine condition, but results should be interpreted alongside maintenance history.
Repairs can materially change the deal. A routine tune-up or inspection may cost about $75-$200, while a major engine repair can reach several hundred dollars or more depending on parts and labor. Ask a dealer to inspect a questionable saw before purchase; a modest inspection fee can be preferable to an unknown repair bill.
Used-market estimates assume a functional saw with ordinary cosmetic wear. Missing parts, major repairs, or a verified recent rebuild can move the price substantially.
Dealer labor and regional pricing affect the out-the-door total
Dealer service rates often fall around $75-$150 per hour, though local shop policies vary. New-saw setup may be included, charged as a modest fee, or bundled with the sale. A repair estimate should identify diagnostic charges, parts, labor, and whether the shop applies the diagnostic fee toward completed work.
For example, 1-2 hours of service at $75-$150 per hour implies $75-$300 in labor before parts. This is a planning calculation, not a standard setup charge for every new saw. Dealer assembly and repair labor should be quoted separately if the listing price is unclear.
Regional differences are real but not fixed. Prices in high-cost metropolitan areas may run roughly 5%-15% above lower-cost rural markets, while remote locations can have fewer dealers and higher transport or service charges. Seasonal tree work and storm cleanup may tighten service schedules, but the saw’s retail price still depends on dealer policy and stock.
Request the out-the-door price in writing, including bar, chain, setup, tax, and any delivery charge. This makes regional comparisons more useful than comparing advertised powerhead prices alone.
Accessories and upkeep add to the first-year budget
A chainsaw price is only part of the ownership cost. A spare chain can cost about $35-$75, and bar oil and two-stroke fuel expenses depend on use and local product prices. A chain sharpener or filing kit may add roughly $15-$100, while a carrying case or other storage equipment can add more.
Protective equipment is a separate and important budget item. Basic chainsaw chaps, helmet, eye and hearing protection, and gloves can total approximately $150-$500, depending on certification, construction, and fit. Higher-end PPE can exceed that range. Do not assume a new saw package includes protective gear.
Routine upkeep includes chain sharpening, cleaning, filter care, and inspection of the bar, sprocket, and safety systems. Professional maintenance charges vary with work required; a basic shop service may be around $75-$200, while repairs involving parts cost extra. Heavy professional use generally brings more frequent chain and bar replacement than occasional property maintenance.
For a new saw with a standard bar, allow about $250-$700 beyond the purchase price for initial PPE and useful accessories. The low end assumes some equipment is already owned; the high end allows for a fuller PPE setup and spare cutting equipment.
Ways to lower the 661 purchase cost without compromising fit
First, compare the same configuration across several authorized dealers. Ask for the exact model, bar length, chain specification, setup charge, tax, and warranty terms. A quote that includes a spare chain is not directly comparable with a powerhead-only price, so request an itemized version when possible.
Choose the bar based on typical work rather than buying the longest option by default. If a standard included bar meets the job, avoiding an immediate upgrade may save roughly $50-$200 or more, depending on the equipment selected. Confirm compatibility and recommended setup before reusing older cutting equipment.
Consider a used saw only after checking condition and repair costs. A verified service history, inspection, and clear return terms can justify paying more than for an untested listing. Avoid treating a low price as a bargain when the saw needs a bar, chain, engine work, or safety repairs.
The most reliable savings come from comparing complete quotes and avoiding unnecessary bar or accessory upgrades. Timing a purchase around dealer inventory changes may help, but a meaningful discount should be weighed against warranty coverage, service access, and the condition of any used saw.
