The Stihl MS 391 price is typically about $760-$900 for a new saw, depending on the dealer, bar length, and included equipment. Buyers comparing the best price should also account for sales tax, chain and bar options, dealer preparation, and whether the saw is new, used, or bundled with accessories.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| New MS 391 powerhead with standard bar | $760 | $830 | $900 | Dealer pricing and local availability vary |
| Longer bar or accessory bundle | $820 | $925 | $1,050 | May include extra chain, case, or maintenance items |
| Used saw in working condition | $350 | $550 | $750 | Condition, service history, and included bar affect value |
| Replacement chain | $25 | $35 | $50 | Price depends on pitch, gauge, and chain length |
What a New Stihl MS 391 Usually Costs
A new MS 391 generally costs $760-$900 before tax, with an approximate national midpoint of $830. That estimate assumes a standard 20-inch bar, a new saw purchased through an authorized dealer, and no premium accessory package. A 25-inch setup or bundled protective equipment can raise the checkout total; a sale or older inventory may bring the saw nearer the low end.
For a straightforward new-saw budget, allow about $830-$975 including typical sales tax. Tax rates differ by state and locality, and some dealers include setup or a first-chain offer while others price those items separately. Confirm the exact bar, chain, warranty terms, and out-the-door amount before comparing advertised prices.
Assumptions: U.S. dealer sale, standard 20-inch bar, ordinary access to inventory, and no financing fees.
How Bar, Chain, and Dealer Preparation Shape the Quote
The powerhead is the largest expense, but the quoted package can include setup, cutting equipment, and delivery. The following ranges are common planning estimates, not fixed national fees; a dealer may combine preparation with the saw price.
| Quote item | Typical price | What changes it | Buying note |
|---|---|---|---|
| MS 391 powerhead and standard bar | $760-$900 | Dealer pricing and inventory | Check bar length and chain specification |
| Longer bar or compatible upgrade | $40-$100 additional | Bar length and brand | Confirm saw configuration is approved |
| Extra replacement chain | $25-$50 each | Pitch, gauge, and drive links | Match the chain to the bar |
| Dealer setup or delivery | $0-$60 | Dealer policy and distance | Ask whether setup is already included |
| Protective gear bundle | $100-$300 | Helmet, chaps, gloves, and boots | Compare included gear with separate purchases |
Package contents matter as much as the sticker price when two dealers advertise different totals. A low quote may omit an extra chain or protective equipment, while a higher bundle may include useful items. Routine setup labor, if charged separately, can be estimated with ; ask the dealer for the actual hours and rate rather than assuming every shop charges this fee.
Which Bar Length and Cutting Job Change the Price
The MS 391 is a 64.1 cc gas chainsaw commonly sold with a 20-inch bar. Moving to a 25-inch bar can add roughly $40-$100 to a package, but the correct configuration depends on the manufacturer’s approved setup and the work. Longer bars also require the matching chain and can increase operating demands; they are not automatically the best value for routine firewood cutting.
Location and access also matter. Dealers in high-cost metro areas may quote about 5%-12% more than lower-overhead rural shops, while limited local inventory can narrow discounts. A drive of 50 miles or more to save $30 may not pay off once fuel and time are counted. Compare final prices from nearby authorized sellers, including tax and delivery.
Bar length, matching chain, and local dealer competition are the most useful quote checks. For logs under 16 inches in diameter, a standard bar may avoid an unnecessary upgrade; frequent cuts on larger wood may justify a longer approved bar. Ask the dealer to specify the included bar and chain rather than relying on a general model listing.
Three MS 391 Price Scenarios at Checkout
These examples show how an advertised price can turn into a practical budget. Tax is estimated at 7% for comparison; actual local rates differ. A standard configuration assumes a 20-inch bar and no unusual delivery charge.
| Purchase scenario | Price build | Estimated total |
|---|---|---|
| Sale-priced new saw | $760 saw + $53 tax | $813 |
| Typical new package | $830 saw + $35 extra chain + $58 tax | $923 |
| Long-bar bundle | $900 saw + $80 bar upgrade + $300 gear + $90 tax | $1,370 |
Separate the saw’s price from optional gear to compare like-for-like quotes. Protective equipment is important for operation, but it can be purchased separately if the bundle does not fit the buyer’s needs. Verify that any discount applies to the exact bar configuration being quoted.
When a Used MS 391 Is Worth the Lower Price
Used MS 391 saws commonly list around $350-$750, with a fair running example often near $500-$600. A low asking price is less attractive if the saw needs a carburetor, bar, chain, or engine work. Repairs can quickly add $75-$250 or more, depending on parts and shop labor, so a used saw with no service record deserves a substantial discount from a new one.
Ask for a cold start, inspect the bar rails and chain tensioner, and check for fuel leaks, damaged housing, and abnormal smoke. A compression test or inspection by a small-engine shop may cost about $20-$60. A seller who cannot demonstrate operation should not be priced like a verified, serviced saw.
Compare the used saw’s purchase price plus immediate repairs with the cost of a dealer-backed new unit. Warranty coverage and return options vary by seller, so get those terms in writing rather than assuming a private sale includes protection.
How to Get the Best MS 391 Price Without Cutting Corners
Request written, out-the-door quotes from at least two or three local dealers. Ask each to list the powerhead, bar length, chain, setup charge, delivery, and tax separately. This makes a genuine discount easier to identify than comparing a bare advertised price with an accessory bundle.
Consider a standard 20-inch package if it matches the cutting work, and skip duplicate accessories already owned. Check for end-of-season inventory or a dealer package discount, but weigh savings against local service availability. Avoid choosing a chain or bar solely because it is cheaper; compatibility and correct setup matter for safe operation.
The strongest savings usually come from comparing identical configurations and declining unneeded upgrades. Keep the final quote, warranty details, and included equipment together so the lowest price is also a clear, usable purchase.
