Husqvarna 450S Rancher vs 450 Rancher: Which One Should You Buy?
The Husqvarna 450S Rancher and 450 Rancher compared on engine, chain speed, oiling, weight, noise, vibration and warranty, with the differences Husqvarna lists.
Verdict: Pick the 450S Rancher if you want Husqvarna’s newer 50 cc saw with the faster chain and an automatic oil pump, and you will confirm the warranty with the seller. Pick the 450 Rancher if you want the proven model with a 2 year warranty stated on its listing. Both use the same 50.2 cc, 3.2 HP engine class, so the difference is in the details.
The Husqvarna 450S Rancher vs 450 Rancher question comes up because they look almost identical on a shelf. Both are 50.2 cc, 3.2 HP gas saws with a 20 in bar for firewood and yard work. This comparison lays out what is the same, what Husqvarna’s own pages say is different, and where the Amazon listings disagree.

Engine, bar and warranty figures are from the Amazon listings collected 8 October 2026. Chain speed, oil pump, weight, sound, vibration and emissions figures are from Husqvarna’s product pages as we read them on 8 October 2026; confirm them on husqvarna.com/us before you buy, because Husqvarna updates its pages and regional versions differ.
Engine and power: the same class
Both saws use a 50.2 cc, 2-cycle X-Torq engine rated at 3.2 HP. That means no difference in engine size or rated power. What Husqvarna does list differently is the speed range: the 450S reaches maximum power at 9,600 rpm, against 9,000 rpm for the 450 Rancher, with peak torque at 6,900 rpm and 7,200 rpm. On the 450S, Husqvarna also says cutting capacity is improved over the 450 Rancher.
Chain speed and oiling
Husqvarna lists a chain speed of 60.7 ft/s at maximum power for the 450S and 56.76 ft/s for the 450 Rancher. A faster chain tends to cut a little quicker with a sharp chain. The 450S also has an automatic oil pump, where the 450 Rancher uses a fixed-flow pump. Either way, check the bar oil level every time you refuel.
Bar and chain
The 450S ships with a 20 in bar and X-CUT chain. The 450 Rancher is sold in 18 in and 20 in versions, and the Amazon listing shows a 20 in X-Force bar. Both take bars from 13 in to 20 in according to their listings. For bucking firewood, 18 to 20 in covers most backyard rounds; use the shorter bar for limbing.
Weight, sound and vibration
On Husqvarna’s pages the powerhead weight is 11.33 lb for the 450 Rancher and 11 lb for the 450S, without cutting equipment. Amazon item weights are higher, 14 lb for the 450 and 14.9 lb for the 450S, because they include the bar, chain and possibly packaging. Husqvarna lists sound at the operator’s ear at 104 dB(A) for the 450 Rancher and 106 dB(A) for the 450S, and rear-handle vibration at 4.9 m/s² against 4.1 m/s². The 450S is a little louder and a little smoother in the hand; either way, wear hearing protection whichever saw you choose, along with chaps, gloves and a helmet with a face screen.
Who each saw suits
For a household that cuts two to five cords a year, either saw does the job, because the engine class and the 20 in bar are the same. The 450S suits buyers who like the idea of the faster chain, the automatic oil pump and slightly lower vibration at the rear handle, and who are comfortable that its Amazon listing is thin on warranty detail and has a contradictory spec table. The 450 Rancher suits buyers who prefer a model with a longer track record and a warranty term stated on the page. In both cases, the real-world difference is smaller than the gap between either saw and a 40 cc yard saw.
Whichever you pick, budget for the extras: a spare chain, a file or sharpening kit, bar oil, a fuel can with the right mix, and the protective gear in the safety box below. A chain that is sharp matters more to cutting speed than the gap in chain speed between these two models.
Emissions
Husqvarna lists 742 g/kWh for the 450 Rancher and 718 g/kWh for the 450S, so the newer saw is slightly cleaner on paper. If you live in California, check that the exact model is sold there.
Warranty and listing quality
This is where the two Amazon listings differ most. The 450 Rancher listing states a 2 year warranty. The 450S listing states none, and its spec table shows 40.9 cc, 2.2 HP, a 16 in bar and 9.7 lb, which look like a smaller saw’s figures from a comparison chart. We used the title and bullets. If you buy the 450S, ask the seller or Husqvarna for the warranty terms before you check out.
Before you buy either saw
Buy from a seller that lists the exact model number: 970515618 appears on the 450 Rancher listing and 970702318 on the 450S. Ask whether the saw ships with the bar and chain fitted, whether it needs a fuel mix and bar oil before first use, and what the return window is. Keep the box and receipt until you have run a few tanks through it, since a saw that will not start or leaks oil is easier to return in the first weeks. Register the saw with Husqvarna, and check the model against recall notices at cpsc.gov before and after you buy.
Which should you buy?
If you want the newer saw and the faster chain, the 450S is the better match. If you value a stated warranty and a longer record, the 450 Rancher is the safe choice. If you cut more than five cords a year, the step up to the 455 Rancher, a 55 cc, 3.5 HP saw with a 2 year warranty on its listing, may be worth a look.

Wear cut-resistant chaps, a helmet with face screen and hearing protection, gloves and sturdy boots. Know where the kickback zone is (the upper tip of the bar), keep the chain brake working and the chain sharp, and never cut alone in the woods. Felling trees is hazardous work: hire a professional for large, leaning or storm-damaged trees, especially near buildings or power lines. See OSHA logging safety for chain saw operators.
