Sickle cutting systems of the type used in mowers, other harvesting machines and the like are disclosed. A sickle is shown consisting of 1½ inches blade spacing with serrated or smooth knife sections, a knifeback bar and a knife head, a plurality of knife or sickle guards with alternate long and short prongs or fingers spaced at two inches of any number that are mounted to the support bar of a mower, harvesting machine, or the like and provide a cutting surface for the sickle, adjustable hold-down clips that hold the knife sections down to the cutting surface, and a driving mechanism with a three-inch stroke such as a wobble joint, a pitman type, or other device which can convert rotary motion to reciprocating motion. In a second embodiment, a staggered sickle cutting system is provided that demonstrates the benefits of the sickle cutting system with even greater efficiency and reduces sickle stress and vibration.
