Dual-Height Mowing System and Method of Use

A dual-height disc cutting apparatus comprising:

• a dual-height cutting mechanism having a mower frame, a double disc cutter device, and an adjustable mounting bracket;
• wherein said double disc cutter device having a top cutter bar assembly and a bottom cutter bar assembly;
• wherein said top cutter bar assembly having a first plurality of rotatable disc units spaced uniformly along a first longitudinal axis of said top cutter bar assembly;
• wherein each of said first plurality of rotatable disc units is a circular cutting disc including a plurality of rotating blades;
• wherein said first plurality of rotatable disc units having a first selectable height to sever forage material at a first selectable height;
• wherein said bottom cutter bar assembly having a second plurality of rotatable disc units arranged along a second longitudinal axis of said bottom cutter bar assembly;
• wherein each of said second plurality of rotatable disc units is a circular cutting disc including a plurality of rotating blades;
• wherein said second plurality of rotatable disc units having a second selectable height to sever the forage material at a second selectable height;
• wherein said second selectable height is lower than said first selectable height;
• wherein said top cutter bar assembly in offset alignment relative to said bottom cutter bar assembly and extends laterally beyond said bottom cutter bar assembly;
• wherein said first plurality of rotatable disc units engage and cut a first portion of the forage prior to said second plurality of rotatable disc units engaging and cutting a second portion of the forage;
• wherein said adjustable mounting bracket independently varies said first selectable height of said first plurality of rotatable disc units and said second selectable height of said second plurality of rotatable disc units relative to the ground surface;
• wherein said adjustable mounting bracket having a pivotable bracket connected to said mower frame for independent vertical translation and angular adjustment of said top cutter bar assembly;
• wherein said adjustable mounting bracket having a linkage arm connected to said bottom cutter bar assembly;
• and
• further wherein said linkage arm is a telescopic rod for independent vertical displacement and height control of said bottom cutter bar assembly.
