Stihl 029 Model Numbers (Reference Chart)
The STIHL 029 is the standard model at about 54.1 cc; the 029 Super is about 56.5 cc. “Farm Boss” is a sales name, not a separate specification, and MS 290 is a related but distinct model. Check the saw’s actual markings and hardware before ordering parts, bars, or chains; the model name alone does not confirm fit.
A durable saw can still become an expensive mistake if its label, replacement parts, or bar setup lead you to the wrong conclusion. When I help identify an older 029, I treat the name as a starting point, not proof of what is inside. Covers and other parts can be changed, and used listings may mix model names.
The safest approach is to record the model marking, serial number, and bar and chain details, then compare them with STIHL service information or a dealer’s parts lookup. There is no reliable universal bar-and-chain setup for every saw called an 029.
STIHL 029 model-number reference chart
This chart separates the main names found on 029-family saws. Displacement means the engine’s swept cylinder volume, measured in cubic centimeters (cc). It helps distinguish the standard 029 from the 029 Super, but it does not identify every part or confirm a saw’s current configuration.
| Marking or name | What it identifies | Approximate displacement | What to verify |
|---|---|---|---|
| 029 | Standard model | 54.1 cc | Actual model marking and installed components |
| 029 Super | Higher-displacement 029 variant | 56.5 cc | Super designation and parts fitment |
| 029 Farm Boss | Common sales or marketing name | Depends on the actual model | Model marking; do not rely on the sales label alone |
| MS 290 | Later, related model | Not an alternate 029 number | Exact model and component markings |
The 029 and 029 Super are not the same displacement. The “Super” label signals a distinct variant, so it matters when checking engine parts or service details. However, displacement alone is not enough to choose a bar, chain, or replacement assembly.
“Farm Boss” can appear in advertisements, decals, or seller descriptions. Treat it as a clue, not a specification. Look for the saw’s actual model designation and compare it with reliable parts information.
MS 290 belongs in the comparison because it is related, but it is not simply another name for the 029. Do not assume that a part or bar listed for one fits the other just because they share design features.
How to identify an 029 and check its serial number
A model marking names the saw; a serial number identifies an individual unit. Neither number, on its own, proves that the saw still has its original parts. Record both, along with visible component markings, before you buy a used saw or order service parts.
Check the saw’s identification markings and the crankcase for stamped or printed numbers. The location and format can vary by version and market, so do not rely on one online photo as a universal guide. Photograph each marking clearly, including any model text on the body.
A serial number is useful when asking a STIHL dealer to check parts or service information. Do not assume that its digits give a simple, universal build date or reveal the saw’s full configuration. If a seller claims a particular year, ask for supporting records rather than treating a number sequence as proof.
| Evidence | What it can tell you | What it cannot prove alone |
|---|---|---|
| Model marking | Whether the saw is identified as an 029, 029 Super, or another model | That all internal parts are original |
| Serial number | A unique identifier a dealer may use for reference | A universally readable production date |
| “Farm Boss” decal or listing | How the saw was marketed or described | The exact model or engine specification |
| Bar stamp | Bar pitch, gauge, and sometimes length or part information | Whether the bar matches the saw’s sprocket |
| Chain markings and link count | Chain size and the number of drive links | Fit on a different bar or sprocket |
A common used-saw problem is a replaced starter cover or decal. The name on that part may not match the crankcase beneath it. If markings conflict, pause and ask a dealer to check the serial and model details against the parts information for the saw.
Bar and chain fitment for an 029
Bar and chain fitment depends on the saw’s exact version and installed parts, not just its model name. Pitch, gauge, and drive-link count must all match the bar, chain, and sprocket system. Confirm these details from the actual components before purchasing a replacement.
- Pitch is the chain’s size class, measured by the spacing of its links.
- Gauge is the thickness of the chain drive links that fit into the bar groove.
- Drive-link count is the number of chain links that run inside the bar groove.
Read the bar stamp and count the drive links on the existing chain. Check the sprocket as well, because pitch must match across the chain and sprocket. Do not assume every 029 uses 3/8-inch or .325-inch pitch, or .050-inch or .063-inch gauge.
The 54–57 cc 029 family is generally suited to bars around 16–20 inches when STIHL approves that setup for the exact saw and components. This is a broad range, not a fitment promise. A shorter approved bar is often a practical choice for routine work, but safe cutting also depends on the wood, the operator, and the condition of the saw.
| If you find… | Check next |
|---|---|
| A replacement chain sold as “for 029” | Pitch, gauge, and drive-link count against your bar and sprocket |
| A bar with no clear stamp | Have a dealer identify it before ordering a chain |
| An MS 290 part advertised as 029-compatible | Verify the exact part number for your model and serial |
| A different bar length from the original | Confirm approval and required chain length for that setup |
A correct size does not make a damaged or poorly maintained setup safe. Inspect the bar groove, oil holes, sprocket, chain, and tension before use. If the component markings are missing or unreadable, get the fitment checked rather than guessing.
Equipment Setup and Safety Preparation
Preparation means checking both the saw’s condition and the work area before starting. It is especially important on an older 029, where wear or replacement parts may be hard to spot. Confirm safety equipment and basic controls first; do not treat a model identification as a safety inspection.
Wear a helmet, eye and hearing protection, chainsaw-rated leg protection, gloves, and suitable boots. Check the chain brake, throttle lockout, chain catcher, fasteners, chain tension, bar condition, and chain-oil delivery. If a safety part is missing or does not work, do not run the saw until it is repaired.
Before cutting, assess the tree or wood, wind, overhead hazards, utilities, bystanders, and escape routes. Follow applicable workplace rules and training requirements, including relevant OSHA or ANSI Z133 requirements where they apply. Keep the guide-bar nose away from wood and other objects: contact near its upper quadrant can cause rotational kickback, a rapid movement of the bar toward the operator.
Use the 029 manual for the exact cold- or warm-start procedure. Start with the chain brake engaged, with the saw on firm ground or held securely by a trained operator. At idle, the chain must remain stationary. If it moves, stop and have the idle or clutch checked.
Field Cutting Operation
A safe cutting setup uses the right approved bar and chain, a sharp chain, and a saw that passes its pre-start checks. No bar length makes a risky cut acceptable. Keep both hands on the saw, maintain secure footing, and work within your training and site limits.
Operate the saw with controlled cuts; do not force a dull chain through wood. Keep the nose clear to reduce kickback risk, and keep other people away from the cutting area. Do not cut above shoulder height. Stop if the saw, chain brake, or chain-oil system does not work as it should.
Maintenance, Sharpening, and Tuning
Maintenance preserves the saw’s condition and helps reveal mismatched parts. Use the manual for the exact model and chain, since file size, depth-gauge settings, and service details can differ. Keep a note of the model, serial number, bar stamp, and chain specifications for future parts orders.
Use the chain manufacturer’s sharpening instructions and gauge tool. A depth gauge controls how much wood each cutter takes; 0.025 inch (0.65 mm) is common, but it is not universal. Set it to the chain maker’s specification rather than relying on a general 029 setting.
Common 029-family service references list about 2,800 rpm at idle and 12,500 rpm maximum. Confirm the correct figures in the manual or service information for the exact saw. Use a tachometer for adjustment; do not tune by ear or exceed the specified maximum.
For fuel, use fresh gasoline mixed 50:1 by volume with approved two-stroke oil, unless the exact manual specifies otherwise. That is 2.6 US fluid ounces of oil per US gallon of gasoline. Never use straight gasoline or unverified fuel, as poor lubrication can damage or seize the engine.
Storage and Seasonal Care
Storage care helps protect an older saw from fuel problems and corrosion. After work, stop the engine and let it cool before refueling or servicing. Follow the manual’s storage directions, and keep fuel in a safe, approved container away from heat or ignition sources.
Engage the chain brake before handling or transporting the saw. Clean the air filter and bar groove, clear the oil holes, and inspect the chain and bar for wear or damage. Store the saw clean and dry, with the bar cover fitted. For longer storage, follow the manual’s instructions for fuel and engine preparation.
Frequently asked questions
These answers address common identification and fitment questions about the 029 family. They are short by design, but a model name alone cannot settle every parts question. When details conflict, use the saw’s markings and component stamps, then confirm with STIHL service information or a dealer.
Is the STIHL 029 the same as the 029 Super?
No. The standard 029 is about 54.1 cc, while the 029 Super is about 56.5 cc. Check the actual model marking before ordering engine parts.
Is the 029 Farm Boss a separate model?
“Farm Boss” is a common sales or marketing designation, not a separate specification by itself. Verify the actual model marking and hardware on the saw.
Is the MS 290 just another name for the 029?
No. The MS 290 is a later related model, not an interchangeable model-number designation. Confirm parts by the exact model and component markings.
Can I decode the 029’s year from its serial number?
Do not assume the number has a simple, universal date code. Ask a STIHL dealer to check it, and request records if a seller claims a specific production year.
What bar length fits a STIHL 029?
The 54–57 cc family is generally suited to approved bars around 16–20 inches, but exact fit depends on the saw and components. Check the manual and bar markings.
What chain size does an 029 use?
There is no universal chain size for every 029. Match pitch, gauge, and drive-link count to the bar and sprocket.
What fuel mix does an 029 use?
Use fresh gasoline and approved two-stroke oil at 50:1 by volume, or 2.6 US fluid ounces of oil per US gallon, while following the exact manual.
How can I check whether a used 029 is genuine?
Compare the model marking, serial number, and visible hardware; ask a STIHL dealer to review the details. A decal or seller description alone is not proof.
What should I do if the model markings and parts do not match?
Do not guess at fitment. Photograph the markings and components, record the serial number, and ask a dealer to identify the saw and check the required parts.
Is 0.025 inch the correct depth-gauge setting for every 029 chain?
No. It is a common setting, not a universal one. Follow the chain manufacturer’s specification and use its gauge tool.
