In one aspect, a shank assembly (100) for an agricultural implement (10) may include a shank (102) and a biasing element (114) configured to exert a biasing force on the shank (102). The shank assembly (100) may also include a reversible mounting plate (120) defining a mounting aperture (136) offset from a centerline (134) of the reversible mounting plate (120) such that a position of a second mounting location (118) of the biasing element (114) relative to a first mounting location (116) of the biasing element (114) differs depending on whether the reversible mounting plate (120) is provided in a first orientation relative to the biasing element or a second orientation relative to the biasing element (114). The biasing element (114) may exert a first biasing force on the shank (102) when the reversible mounting plate (120) is oriented in the first orientation and a second, different biasing force on the shank (102) when the reversible mounting plate (120) is oriented in the second orientation.
