Stihl MS 290 Farm Boss Chain Questions

What size chain does a Stihl MS 290 take?

The MS 290 Farm Boss most commonly runs 3/8" pitch in either 0.050" (1.3mm) or 0.063" (1.6mm) gauge — some units shipped with a .325" bar instead, so it is essential to check the stamp on your bar before ordering. Drive link count for the 3/8" bars: 60 DL (16"), 66 DL (18"), 72 DL (20").

How many drive links is an MS 290 chain?

Count depends on bar length and pitch — see above. The DL count is usually stamped on the bar itself, or count the drive links on your old chain. If your bar reads .325", message us and we'll match it. You can also use our Search by Chainsaw tool.

Is this a genuine Stihl chain?

No — it's an Alpine Chain Co. chain manufactured to fit the MS 290, replacing the Stihl 33 RS3 / 36 RS3 and Oregon 72EXL / 73EXL. Same pitch, gauge and drive link options, with a semi-chisel profile chosen for Australian hardwood. Every fit is backed by our Guaranteed Fit system.

How to Verify Your Chain Size

If you are unsure if this is the correct chain for your Stihl MS 290 Farm Boss, check the side of your current guide bar. The Pitch, Gauge, and Drive Link (DL) count are typically stamped directly into the bar near the mounting bolts.
