An agricultural implement includes a main frame assembly, a track assembly coupled to the main frame assembly, and a toolbar coupled to the main frame assembly. Furthermore, the agricultural implement includes a caster wheel assembly including a linkage assembly coupled to the toolbar, an actuator, and a caster wheel. The caster wheel is pivotally coupled to the linkage assembly to enable the caster wheel to caster relative to the linkage assembly while the toolbar is in a working position and in a raised position. In addition, the actuator is configured to control a vertical position of the caster wheel relative to the toolbar. The actuator has a first end and a second end, and the second end is positioned between a bottom link and a top link of the linkage assembly.
