ECHO CS-590 vs STIHL MS 271: Power, Weight, and Buyer Fit

Bottom line

The ECHO CS-590 is the heavier-cut choice; the STIHL MS 271 is the lighter powerhead choice for mixed property work. That is the useful difference. The old version of this page sent both products to generic Amazon searches and declared comfort and cutting winners without grounding those claims in current package identities.

ECHO’s CS-590 uses a 59.8 cc two-stroke engine and weighs 13.2 pounds as a dry powerhead without bar and chain. STIHL’s MS 271 uses a 50.2 cc engine, publishes 2.6 kW, and lists a 12.4-pound powerhead without fuel, bar, or chain. The roughly 0.8-pound powerhead difference is real; the finished ready-to-cut difference also depends on the bar, chain, fuel, and oil each buyer selects.

Specification comparison

These are powerhead specifications, not promises about cut speed. Chain condition, sharpening, bar length, wood species, operator technique, and maintenance can overwhelm a paper advantage.

Choose the ECHO CS-590 when…

The work regularly reaches larger wood

The CS-590’s 59.8 cc displacement places it closer to a 60 cc work pattern. ECHO offers 18-, 20-, and 24-inch variants, so buyers can choose a package around the actual work rather than buying one vague “CS-590” listing.

That does not mean the longest available bar is automatically best. A longer cutting attachment adds weight and changes handling. Read our chainsaw bar-length guide before choosing the package.

You want an adjustable oiler

ECHO specifies an automatic, adjustable, clutch-driven oiler. The clutch-driven design oils while the chain moves, and adjustment gives the owner a manufacturer-supported control for different cutting attachments and conditions. Follow the operator’s manual rather than guessing at an oil setting.

The exact package and service route are verified

The Amazon link on this page is for CS-590-20AA, ASIN B00KXM6OT6, the 20-inch package. Before ordering, confirm the seller, model suffix, bar length, package contents, warranty eligibility, and where local ECHO service is available. The lower-friction purchase is the one you can service, not simply the one with the larger engine.

Lower powerhead weight matters

STIHL’s 12.4-pound published powerhead weight is about 0.8 pound below ECHO’s 13.2-pound figure on a like-for-like basis before cutting attachments and fluids. That difference is not dramatic for one cut, but it belongs in the decision for repeated limbing, repositioning, and mixed property cleanup.

Do not mistake lower weight for a claim that every user will find it more comfortable. Bar choice, balance, grip, PPE, and fatigue differ. Handle the configured saw at a dealer if possible.

A current STIHL purchase path is more convenient

STIHL’s U.S. product page lists exact 18- and 20-inch variants and routes purchase through its current distribution system. That is a better path than an unverified marketplace search for a model name. It also lets a buyer confirm the local service relationship before purchase.

Your work is mixed rather than consistently heavy

STIHL positions the MS 271 for firewood, agriculture, construction, horticulture, and storm cleanup. Its 50.2 cc engine and 16- to 20-inch class in the current catalog make sense for owners who want a farm-and-ranch saw without moving up solely for occasional large wood.

Engine size is not the whole decision

The CS-590 has the displacement advantage, but displacement does not tell you chain sharpness, kerf, bar condition, balance, fuel freshness, or service quality. We do not convert ECHO’s 59.8 cc figure into a made-up horsepower number because ECHO’s current U.S. page does not publish a directly comparable output figure.

The better decision sequence is:

1. define the typical diameter and species, not the single largest emergency cut;
2. choose an appropriate bar range;
3. confirm total ready-to-cut weight and balance;
4. check local parts and service access;
5. compare the exact included bar and chain package; and
6. budget for PPE, files, wedges, fuel, oil, and spare chain.

Our chainsaw buying guide for beginners covers those setup costs before the model decision.

Chain and bar identity: do not guess

ECHO lists a 3/8-inch-pitch 72LPX chain family for the CS-590, but the drive-link count changes with the bar. STIHL’s product page identifies the 18-inch MS 271 variant with a specific .325-inch Rapid Micro chain package. Those are not interchangeable systems.

When ordering a spare, match the saw model, bar part number, pitch, gauge, and drive-link count printed on the installed setup. “Fits a 20-inch chainsaw” is not enough. The same nominal bar length can use different chain specifications.

Keep the selected chain sharp using the correct file and depth-gauge procedure. A dull chain increases feed pressure and makes a good saw feel weak. See our practical chain-sharpening guide for the checks that matter.

Safety and ownership costs

Both are full-size gasoline chainsaws capable of severe or fatal injury. Read the exact operator’s manual, wear the specified protective equipment, understand reactive forces and kickback, and do not operate from a ladder or unstable position. Our chainsaw safety guide is a starting point, not a replacement for the manufacturer manual or competent instruction.

Budget for:

• correctly specified helmet, eye, hearing, leg, hand, and foot protection;
• fresh manufacturer-compliant fuel mix;
• bar and chain oil;
• the correct sharpening tools;
• at least one exact spare chain;
• wedges and felling tools appropriate to the task; and
• professional work for trees or situations beyond your training.

A cheaper powerhead does not save money if the buyer cannot obtain service or buys the wrong cutting attachment.

Which one should you buy?

Buy the ECHO CS-590 when frequent firewood, larger timber, or storm cleanup makes the 59.8 cc platform and adjustable oiler valuable, and the exact ECHO package has a workable service path.

Buy the STIHL MS 271 when the lower dry powerhead weight, current STIHL purchase route, and 18- or 20-inch mixed-property setup better match the work.

Buy neither if the job is occasional light pruning, if the largest cuts should be handled by a trained tree professional, or if you have not budgeted for PPE and maintenance. A smaller battery saw or pole pruner may be more useful for routine small-limb work, but it is not a substitute for professional removal of hazardous trees.

Verdict

There is no honest universal winner. The CS-590 gives the buyer a larger-displacement, heavier-cut platform; the MS 271 gives up displacement while reducing published dry powerhead weight and offering a clear current STIHL purchase route.

Choose from the actual workload and exact package. For the ECHO, verify CS-590-20AA / B00KXM6OT6 if using the Amazon path. For the STIHL, select the 18- or 20-inch variant on the manufacturer’s product page rather than trusting a generic marketplace result.
