The mower is a Husqvarna iz4819, & I am wandering if anyone can tell me the lenght & width of the pump belt. The Husq PN is 539106887 & Oregon PN is 510201401. I have spent 1 1/2 hrs on Oregon site looking w/ no luck. My dealer has it backordered so I bought a belt @ auto parts store, but not sure if it will work b/c it's 1/2" longer than the belt that broke. Dealer is closed or I wolud call them. Thank You in advance for any help.
