1. A knife drive assembly for a harvesting header operable to move a first knife and a second knife in reciprocating transverse motion, the assembly comprising:
(a) an interface mechanism operable to couple with a power source to cause rotational movement of a rotating member;
(b) a first movement conversion mechanism operable to convert the rotational movement of said rotating member to reciprocating generally longitudinal movement of a first generally longitudinally extending movement member and said first movement conversion mechanism operable to convert the rotational movement of said rotating member to reciprocating generally longitudinal movement of a second generally longitudinally extending movement member;
(c) a second movement conversion mechanism operable to convert the reciprocating generally longitudinal movement of the first generally longitudinally extending movement member to transverse reciprocating movement of the first knife; and wherein said second movement conversion mechanism operable to convert the reciprocating generally longitudinal movement of the second generally longitudinally extending movement member to transverse reciprocating movement of the second knife.
