Abstract
A knife section for use with a reciprocating cutter bar assembly of an agricultural machine includes a mounting base. A first knife extends outwardly from the mounting base. The first knife has a first linear extent from the mounting base. A second knife extends outwardly from the mounting base. The second knife has a second linear extent from the mounting base different than the first linear extent.
Claims12
A cutter bar assembly for use in an agricultural machine, said cutter bar assembly having a direction of reciprocation, comprising:
- an elongate knifeback;
- and
- a plurality of knives connected to said elongate knifeback, said plurality of knives extending outwardly from said elongate knifeback in a direction perpendicular to said direction of reciprocation, said plurality of knives including:
- a first subset of knives having a first linear extent, each knife of said first subset of knives having a first pair of cutting edges of substantially equal length, and
- a second subset of knives having a second linear extent different than said first linear extent, each knife of said second subset of knives having a second pair of cutting edges of substantially equal length.
