Introduction
The Stihl MS 290 Farm Boss is one of the most recognized chainsaw names in America. For over two decades, it has been the go-to choice for farmers, ranchers, and property owners who need a reliable, no-nonsense workhorse. While newer models like the MS 251 and MS 311 offer updated technology, the MS 290 continues to sell because it does one thing extremely well: it cuts wood.
We tested the MS 290 against its modern successors and competitors to determine whether this classic design still earns its legendary reputation.
At a Glance: Farm and Ranch Comparison
| Feature | Stihl MS 290 | Stihl MS 251 | Stihl MS 311 | Husqvarna 450 Rancher |
|---|---|---|---|---|
| Displacement | 56.5 cc | 45.4 cc | 59.0 cc | 50.2 cc |
| Power Output | 3.9 bhp (2.9 kW) | 3.0 bhp (2.2 kW) | 4.0 bhp (3.0 kW) | 3.2 bhp (2.4 kW) |
| Powerhead Weight | 12.3 lbs (5.6 kg) | 10.1 lbs (4.6 kg) | 12.8 lbs (5.8 kg) | 11.7 lbs (5.3 kg) |
| Engine Type | Conventional 2-MIX | 2-MIX Stratified | 2-MIX Stratified | X-Torq |
| Decompression Valve | No | No | Yes | No |
| Price Range | $450-550 | $450-550 | $550-650 | $450-500 |
The MS 290 holds its own in this comparison. At 56.5cc, it produces 3.9 bhp — more than the MS 251 and comparable to the MS 311. The conventional engine design is simpler and easier to maintain than the 2-MIX stratified engines, which some users prefer.
The Classic Engine Design
The MS 290 uses a conventional two-stroke engine with a Walbro carburetor. There is no M-Tronic, no EFI, no stratified scavenging. This simplicity is both its greatest strength and its limitation.
Why Simplicity Matters
For farm and ranch users who may not have a Stihl dealer nearby, the MS 290’s conventional carburetor can be adjusted with a standard scrench. The engine is well-understood by small engine mechanics everywhere. Parts are widely available and affordable.
Starting
The MS 290 uses a traditional three-position choke system:
- Full choke — pull until engine pops
- Half choke — pull to start
- Run — normal operation
Cold starts typically require 3-5 pulls; warm starts are usually 1-2 pulls. There is no decompression valve, so the pull cord requires more effort than newer models. For users with limited upper body strength, this is a consideration.
Durability and Longevity
The MS 290 has earned its reputation for one reason: it lasts. The engine design has been refined over decades, and the simplicity means fewer things to fail.
Real-World Durability
We spoke with multiple farm owners who have run MS 290s for 15-20+ years with basic maintenance. The engine is designed for sustained use in dusty, dirty conditions. The polymer crankcase is not as durable as magnesium (found on professional saws), but for the intended use case, it is more than adequate.
Common Issues
- Carburetor gumming: Caused by ethanol fuel sitting in the tank. Use ethanol-free fuel or drain the tank before storage.
- Air filter clogging: Check and clean every 5-10 hours of use in dusty conditions.
- Chain dulling: The 3/8-inch pitch chain stays sharp longer than full-chisel professional chains but cuts slower.
Maintenance
The MS 290 is designed for easy homeowner maintenance:
- Air filter: Simple felt-style design, washable with warm soapy water
- Spark plug: Standard replacement every 100 hours or annually
- Carburetor: Adjustable with a scrench — no special tools required
- Chain tensioning: Side-access tensioner for quick adjustments
- Bar maintenance: Clean bar groove regularly and rotate to prevent uneven rail wear

Chainsaw Safety
Even a 56cc saw can cause serious injury. Always wear eye protection, hearing protection, and cut-resistant chaps. Never cut above shoulder height with a rear-handle saw.
Read our chainsaw safety guide before your first cut.
Gas vs Battery
For occasional trimming, battery saws offer convenience. But when you need to process multiple cords or work for several hours without battery swaps, the MS 290 delivers superior runtime. For farm and ranch work, gas remains the practical choice.

Who Should Buy the MS 290
The MS 290 is for:
- Farm and ranch owners who need a reliable, proven workhorse
- Homeowners with large property who cut firewood regularly
- Users who prefer simplicity over electronic engine management
- Anyone who values proven reliability over cutting-edge technology
If you are a full-time professional, look at the MS 261 or MS 362. If you want the latest technology, look at the MS 251 or MS 311. But if you want a chainsaw that has been proven over decades and will keep running with basic maintenance, the MS 290 Farm Boss is hard to beat.
Pros & Cons
Pros:
- Proven, reliable engine design with decades of track record
- Simple carburetor can be adjusted with basic tools
- Parts widely available and affordable
- 56.5cc provides serious power for farm and ranch work
- Excellent value for the power output
- Stihl build quality and dealer network
- Strong resale value
Cons:
- Heavier than the MS 251 (12.3 lbs vs 10.1 lbs)
- No decompression valve — harder to pull start
- Conventional carburetor requires manual adjustment
- Not as fuel-efficient as 2-MIX stratified engines
- Polymer crankcase (not magnesium like pro saws)
- Fixed non-adjustable bar oiler
Final Verdict
The Stihl MS 290 Farm Boss is a chainsaw that needs no introduction. It has been the default choice for American farmers and ranchers for over two decades, and for good reason: it is reliable, powerful, and built to last.
The technology may be dated compared to the MS 251 or MS 311, but that simplicity is exactly what makes it appealing. When you are deep in the pasture with a fallen tree blocking the road, you need a saw that starts and cuts. The MS 290 does that better than almost anything in its class.

FAQ
What is the difference between the MS 290 and the MS 311?
The MS 311 is the successor to the MS 290 with a more fuel-efficient stratified scavenging engine that reduces emissions. The 311 also features a decompression valve and tool-less fuel cap. The MS 290 uses a simpler, proven engine design that many users find easier to maintain.
What does the MS 290 weigh?
The MS 290 powerhead weighs approximately 12.3 lbs (5.6 kg). With an 18-inch bar and full fluids, expect around 15-16 lbs total. It is heavier than the MS 251 but lighter than professional saws like the MS 261.
What is the best bar length for the MS 290?
The MS 290 is optimized for an 18-inch or 20-inch bar. It can handle a 24-inch bar for occasional use in softer woods, but for regular work, an 18-inch bar provides the best balance of chain speed and reach. Avoid bars longer than 24 inches.
What chain does the MS 290 use?
The MS 290 uses a 3/8-inch pitch chain with .050-inch gauge. The OEM chain is the Stihl 23RS (Rapid Super) full-chisel chain. For longer sharpness retention in dirty conditions, consider a semi-chisel chain like the 23RM3.
What fuel mix does the MS 290 require?
The MS 290 requires a 50:1 ratio of 89+ octane gasoline with 2-cycle air-cooled engine oil. Use Stihl HP Ultra synthetic oil for best results. Ethanol-free fuel is strongly recommended to prevent carburetor issues, especially for seasonal users.
