Agricultural mowing device

An agricultural mowing device comprising:

• a linkage assembly for attaching to a towing vehicle;
• a shaft having an upper end coupled to the linkage assembly for being towed in a field between two adjacent rows of planted matter;
• a cutting device mounted to the shaft for cutting plant material, the cutting device extending laterally from the shaft to a distance covering at least a portion of at least one of the two adjacent rows for cutting the plant matter that grows in the at least one of the two adjacent rows;
• and
• a sensor for sensing a desired cutting height of the planted matter and being communicatively coupled to the cutting device, the sensing causing an automatic adjustment along the shaft of the cutting device to cut the plant matter at the desired cutting height.

A method for cutting plant matter with an agricultural mowing device, the method comprising:

• attaching a linkage assembly to a towing vehicle;
• advancing the linkage assembly in a field of planted matter with a shaft being positioned between two adjacent rows of the planted matter, the shaft having an upper end coupled to the linkage assembly;
• cutting with a primary cutting device shorter plant material that grows between the two adjacent rows, the primary cutting device being mounted to a lower end of the shaft;
• cutting with a secondary cutting device taller plant material that grows at least in part in at least one of the two adjacent rows, the secondary cutting device being mounted near the upper end;
• sensing with one or more sensors a desired cutting height of the shorter plant material or the taller plant material;
• and
• based on the sensing, automatically adjusting at least one of the primary cutting device or the secondary cutting device to the desired cutting height.
