ABSTRACT:
A transponder reader arm assembly is useful with feed cars for automatically feeding livestock in order to place a transponder reader in close proximity to a transponder worn by the livestock. The transponder reader arm assembly hereof includes a pivotally mounted arm connected to a mounting bracket at an inboard end and presenting an outwardly extending distal end having a transponder reader connected thereto. The transponder reader arm includes a biasing spring which serves to center the arm to an outwardly extending orientation. The transponder reader may be mounted directly to the distal end of a single arm or to a connecting linkage between a pair of parallel arms.
