50.2 cc ranch saw. Stock 18″ setup: .325″ pitch, .050″ gauge, 72 drive links — Husqvarna H30 / X-CUT SP33G.
The 450 Rancher is a 50.2 cc X-Torq ranch saw, most commonly sold in North America with an 18″ narrow-kerf bar. Its factory chain — Husqvarna H30, now also sold as X-CUT SP33G — is a .325″ pitch, .050″ gauge loop with 72 drive links at 18″, sharpened with a 3/16″ file. An owner's actual bar for this saw, stamped “18″ · .325 · 050 · 72”, is the worked example in our verification guide.
