System for side-to-side drum leveling

A system for adjusting a leveling of a drum of a row unit of an agricultural harvester, comprising:

• a carriage assembly configured to couple to a drum that is configured to pick an agricultural product, wherein the carriage assembly comprises:
• a first pair of rollers configured to interface with a top of a toolbar of a header of the agricultural harvester with a first roller and a second roller of the first pair of rollers disposed adjacent opposite longitudinal ends of the carriage assembly;
• and
• a second pair of rollers configured to interface with a side of the toolbar with a third roller and a fourth roller of the second pair of rollers disposed adjacent the opposite longitudinal ends of the carriage assembly;
• a first adjustment mechanism having a first end coupled to a first longitudinal end of the carriage assembly and a second end configured to couple to a first side of a housing of the drum;
• and
• a second adjustment mechanism having a third end coupled to a second longitudinal end of the carriage assembly opposite the first longitudinal end and a fourth end configured to couple to a second side of the housing of the drum opposite the first side;
• and
• wherein the first adjustment mechanism and the second adjustment mechanism are configured adjust a levelness of the drum relative to an adjacent drum hanging on the toolbar.

A row unit for an agricultural harvester, comprising:

• a drum configured to pick an agricultural product and comprising a housing;
• and
• a hanger assembly coupled to the housing of the drum, wherein the hanger assembly comprises:
• a first vertical arm bracket and a second vertical arm bracket coupled to opposite sides of the housing of the drum;
• and
• a bracket extending between and coupled to the first vertical arm bracket and the second vertical arm bracket;
• wherein the first vertical arm bracket comprises a first end and a second end opposite the first end, wherein the first end is coupled to the housing and the second end is coupled to a first hub coupled to a first roller;
• wherein the second vertical arm bracket comprises a third end and a fourth end opposite the third end, wherein the third end is coupled to the housing and the fourth end is coupled to a second hub coupled to a second roller, wherein the hanger assembly is configured to hang on a toolbar of a header of the agricultural harvester via the first roller and the second roller;
• and
• wherein the first roller is coupled to a cam system configured to adjust a position of the first roller relative to the toolbar to adjust a levelness of the drum relative to an adjacent drum hanging on the toolbar.
