ABSTRACT:
A leveling linkage is provided on a planter unit of a planter implement. Each planter unit includes a leveling spring for supporting a back end of the plant unit in its raised, transport position. The leveling linkage is connected to a mounting bracket and a draft frame of the planter unit, which move relative to each other when the implement is raised and lowered. The leveling linkage extends the leveling spring when the implement is in its transport position and retracts the leveling spring when the implement is in its work position.
