Abstract
A caster wheel assembly includes a frame configured to pivotally couple to a tool bar, a sub-frame rotatably coupled to the frame, and a connecting linkage configured to control movement of the frame relative to the tool bar. The caster wheel assembly also includes a locking assembly, which includes a lock lever movably coupled to the frame, wherein the lock lever includes a locking element and a release element, a locking structure fixedly coupled to the sub-frame, and a driving element fixedly coupled to the connecting linkage. The locking element is configured to block rotation of the sub-frame relative to the frame while the locking element is engaged with the locking structure, and the driving element is configured to contact the release element as the connecting linkage moves the frame downwardly relative to the tool bar to drive the locking element to disengage the locking structure.
