I have a 455 Rancher, PN 966 03 73-20, SN 20101101161 what is the correct IPS (Parts List) to download from the Husqvarna Website? A suggestion to make downloading documents easier for the consumer is, instead of typing in the model number and getting multiple manuals or parts lists, not knowing which is the correct one. Type in the part number listed on the Serial Number Plate for the piece of Equipment. This way only the one correct OM or IPS will come up. Many Part numbers can be linked to one document, instead of many manuals listed for one model number.
