Abstract
An agricultural vehicle including a chassis and a header carried by the chassis that includes a cutterbar assembly with a plurality of cutting units. Each of the cutting units includes a rotatable disc carrying a plurality of knives each defining at least one cutting edge and a guard assembly including a plurality of extensions. Each of the extensions includes a bottom guard portion connected to a top guard portion to define a knife slot that allows the plurality of knives to pass through during rotation of the disc. At least one rotary driver couples to the rotatable disc of at least one of the cutting units.

An agricultural vehicle, comprising:
- a chassis;
- a header carried by the chassis, the header including a cutterbar assembly with a plurality of cutting units, each of the cutting units including:
- a rotatable disc carrying a plurality of knives each defining at least one cutting edge;
- and
- a guard assembly including a plurality of extensions, each of the extensions including a bottom guard portion connected to a top guard portion to define a knife slot that allows the plurality of knives to pass through during rotation of the disc;
- and
- at least one rotary driver coupled to the rotatable disc of at least one of the cutting units,
- wherein the plurality of cutting units include a first cutting unit and a second cutting unit, the first cutting unit and the second cutting unit being positioned such that the plurality of knives of the first cutting unit define a first rotational region and the plurality of knives of the second cutting unit define a second rotational region that partially overlaps the first rotational region.
A header for an agricultural vehicle, comprising:
- a header frame;
- a cutterbar assembly with a plurality of cutting units carried by the header frame, each of the cutting units including:
- a rotatable disc carrying a plurality of knives each defining at least one cutting edge;
- and
- a guard assembly including a plurality of extensions, each of the extensions including a bottom guard portion connected to a top guard portion to define a knife slot that allows the plurality of knives to pass through during rotation of the disc;
- and
- at least one rotary driver coupled to the rotatable disc of at least one of the cutting units,
- wherein the plurality of cutting units include a first cutting unit and a second cutting unit, and the plurality of knives of the first cutting unit are vertically offset from the plurality of knives of the second cutting unit.
A header for an agricultural vehicle, comprising:
- a header frame;
- a cutterbar assembly with a plurality of cutting units carried by the header frame, each of the cutting units including:
- a rotatable disc carrying a plurality of knives each defining at least one cutting edge;
- and
- a guard assembly including a plurality of extensions, each of the extensions including a bottom guard portion connected to a top guard portion to define a knife slot that allows the plurality of knives to pass through during rotation of the disc, and wherein the top guard portion includes a sharpened edge;
- and
- at least one rotary driver coupled to the rotatable disc of at least one of the cutting units.
