Abstract
A cultivator for post-planting cultivation. The cultivator includes a main frame. A chisel member has one end portion coupled to the frame and a second end portion spaced from the first end portion along a longitudinal axis of the chisel member for cultivating soil during operation of the cultivator. A heave limiter is coupled to the frame ahead of the chisel member relative to the direction of operation of the chisel cultivator. The chisel member is adjustable relative to the frame to adjust the distance of the second end portion of the chisel member from the frame. A sweep assembly is coupled to the frame behind the chisel member relative to the direction of operation of the cultivator. The sweep assembly includes wings which extend outwardly of a centerline extending in the direction of operation of the cultivator in a plane substantially orthogonal to the longitudinal axis of the chisel member. A sifting assembly is coupled to the sweep assembly. The sifting assembly allows the sweep to be run deeper to provide a larger volume of cultivated soil with an effective weed kill.
