Abstract
A cultivator includes at least one cultivator row unit, each of the at least one cultivator row unit having a support assembly for securing the cultivator row unit to a tool bar, a shank, an earth working tool operatively connected to the shank, and at least one assembly for providing discrete incremental adjustment for at least one of (a) an angle of the earth working tool, (b) a depth of the earth working tool, and (c) a gauge wheel depth.
Claims17
A cultivator comprising at least one cultivator row unit, each of the at least one cultivator row unit comprising:
- a support assembly for securing the cultivator row unit to a tool bar;
- a shank;
- an earth working tool operatively connected at a first end of the shank;
- arcuate gearing positioned at a second end of the shank;
- a first quick adjustment assembly configured for discrete incremental adjustment of position of the quick adjustment assembly relative to the arcuate gearing to adjust angle of the earth working tool relative to a ground plane;
- and
- a second quick adjustment assembly comprising a gear having teeth for meshing with arcuate gearing of a linkage and positioned to provide for incrementally adjusting position of the second quick adjustment assembly relative to the arcuate gearing of the linkage to adjust depth of the earth working tool.
A cultivator comprising at least one cultivator row unit, each of the at least one cultivator row unit comprising:
- a frame;
- a support assembly operatively connected to the frame for securing the cultivator row unit to a tool bar;
- a shank operatively connected to the frame;
- an earth working tool operatively connected to the shank;
- a gauge wheel assembly operatively connected to the frame, the gauge wheel assembly comprising a first gauge wheel and a second gauge wheel;
- at least one quick adjustment assembly positioned to mesh with teeth of arcuate gearing such that position of the quick adjustment assembly is discretely and incrementally adjustable relative to the arcuate gearing;
- wherein the at least one quick adjustment assembly for providing discrete incremental adjustment comprises a gear with teeth, a handle integral with the gear and arcuate gearing having teeth engaging the teeth of the gear;
- wherein each of the at least one quick adjustment assembly is configured for providing discrete incremental adjustment for one of (a) an angle of the earth working tool, (b) a depth of the earth working tool, and (c) a gauge wheel depth associated with the gauge wheel assembly.
An apparatus for use in an agricultural implement to provide discrete incremental adjustment without use of tools, the apparatus comprising:
- an arcuate member with teeth extending outwardly therefrom;
- a gear having teeth for engaging the teeth of the arcuate member;
- a handle integral with the gear;
- a first support member and a second support member on opposite sides of the gear having teeth;
- and
- a fastener for securing the gear to the arcuate member such that in a fastened position the faster engages the teeth of the gear thereby preventing rotation of the gear relative to the arcuate member.
