ABSTRACT:
A blade guide for supporting a reciprocating sickle blade in an agricultural mower. The blade guide includes a unitary, integrally formed structure formed of a resilient, molded thermoplastic material. To avoid wear, metallic wear plates are provided where the reciprocating sickle blade contacts the blade guide. The side edges of the wear plates cooperate with the reciprocating sickle blades to provide a cutting action as the sickle blades reciprocate. In one embodiment, the side edges of the wear plate are beveled to improve the cutting action. Preferably, the wear plates are molded in place during manufacture.
