Oregon Revised Statutes Mortgages and Liens § 87.146

(a) Liens created by ORS 87.152 to 87.162 have priority over all other liens, security interests and encumbrances on the chattel subject to the lien, except that taxes and duly perfected security interests existing before chattels sought to be subjected to a lien created by ORS 87.162 are brought upon the leased premises have priority over that lien.

(b) Liens created by ORS 87.216 to 87.232 have equal priority. When a judgment is given foreclosing two or more liens created by ORS 87.216 to 87.232 upon the same chattel, the debts secured by those liens shall be satisfied pro rata out of the proceeds of the sale of the property.

(c) With regard to the same chattel, a lien created by ORS 87.216 to 87.232 has priority over a nonpossessory chattel lien created by any other law.

(d) With regard to the same chattel, a lien created by ORS 87.216 is junior and subordinate to a duly perfected security interest in existence when the notice of claim of such lien is filed under ORS 87.242.

(e) With regard to the same chattel, a lien created by ORS 87.222 to 87.232 has priority over a security interest created under ORS chapter 79.

(2)(a) A personal property tax lien, a chattel lien claimed by the State of Oregon, its agencies or any political subdivision thereof, and a chattel lien claimed by a state officer or employee during the course of official duty pursuant to law have priority over a lien created by ORS 87.152 to 87.162 and 87.216 to 87.232.

(b) A duly perfected security interest of a lessor in any portion of crops or animals to pay or secure payment of rental of the premises upon which those crops or animals are grown, not to exceed 50 percent of those crops or animals, shall not be subject to the lien created by ORS 87.226.
