(a) As used in this Code section, the term:
(1) “Dealer” means any person who is engaged in the business of selling farm equipment at retail.
(2) “Farm equipment” means any vehicle as defined in Code Section 40-1-1 which is self-propelled and which is designed and used primarily for agricultural, horticultural, forestry, or livestock raising operations.
(b) Self-propelled farm equipment which is owned by a dealer and held in inventory for sale or resale shall constitute a separate subclassification of motor vehicle within the motor vehicle classification of tangible property for ad valorem taxation purposes. The procedures prescribed in this chapter for returning self-propelled farm equipment for ad valorem taxation, determining the application rates for taxation, and collecting the ad valorem taxes imposed on self-propelled farm equipment do not apply to self-propelled farm equipment which is owned by a dealer and held in inventory for sale or resale. Such self-propelled farm equipment which is owned by a dealer and held in inventory for sale or resale shall not be returned for ad valorem taxation, shall not be taxed, and no taxes shall be collected on such self-propelled farm equipment until it is transferred and then otherwise, if at all, becomes subject to taxation as provided in this chapter.
