| 26 | Agricultural apparatus having vertically adjustable disc gang assemblies | US841372 | 1992-02-25 | US5207279A | 1993-05-04 | Marvin L. Nelson; Jimmy R. Kreftmeyer |
| An agricultural apparatus having a combination of ground engaging tools thereon. The agricultural apparatus includes a plurality of ground engaging cultivator tools mounted on a frame assembly which is specifically configured to promote accurate lateral spacing of the cultivator tools thereon. The agricultural apparatus further includes a pair of disc gang assemblies arranged on opposite lateral sides of the longitudinal centerline of the implement and a lift mechanism for conjointly elevating and positioning the disc gang assemblies relative to the frame assembly. The frame assembly is comprised of a series of interconnected frame members including laterally extending tool bars. Each cultivator tool is adjustably secured to a respective tool bar by a resiliently biased bracket assembly. To facilitate lateral adjustment of the cultivating tools, the tool bars are fixedly connected in spaced relation to other frame members. The spacing between the tool bars and other frame members allows the tool carrying bracket assembly to fit therebetween thus facilitating lateral spacing of the tools relative to each other. | ||||||
