Questions people ask

What size chain does a Husqvarna 450X Rancher take?

How many drive links is a Husqvarna 450X Rancher chain?

It depends on the bar: 56 on a 13" bar, 66 on a 16" bar, 66 on a 16" bar, 72 on a 18" bar, 72 on a 18" bar, 78 on a 20" bar, 80 on a 20" bar. The bar length is usually printed near the mount.

Can I use a chain with the same length but different pitch?

No. Pitch and gauge have to match the bar and sprocket, and the drive link count has to match the bar. A chain that is off on any of the three will not fit or run safely.
