Husqvarna 455 Rancher chain size
55.5 cc ranch saw. Factory 20″ setup per Husqvarna's own manual table: 3/8″ pitch, 72 drive links — in both .050″ and .058″ gauge versions.
The 455 Rancher is Husqvarna's long-running 55.5 cc farm and ranch saw. Husqvarna's operator-manual bar & chain combination table lists this saw with 3/8″ pitch chain at 20″ (72 drive links) in two gauges, plus a family of .325″ combinations at shorter lengths. The gauge is the trap on this model: both versions exist from the factory, so two owners with “the same saw” can need different chains.

How do I check the chain size on my Husqvarna 455 Rancher?
Take the clutch cover off, lift the bar out and read the stamp on the bar tail: it shows bar length, pitch, gauge and usually the drive-link count. Match all three numbers; if your stamp disagrees with a chart, order to the stamp.
What file size sharpens the Husqvarna 455 Rancher chain?
7/32″ (5.2 mm) or 3/16″ (4.8 mm) round file, depending on the pitch of the chain fitted. File size follows pitch: 3/8 inch low-profile takes 5/32 inch, .325 inch takes 3/16 inch, and standard 3/8 inch takes 7/32 inch.
