20080308020 | PRECISION HOE OPENER WITH SWING LINK BETWEEN CYLINDER AND SHANK - A precision hoe opener assembly is provided with improved accuracy of seeding as well as improved control over the opener and packer wheel assemblies. The opener assembly includes a hydraulically-driven parallel linkage assembly, a lost motion linkage, a hoe opener, and a packer wheel. The design provides improved seeding accuracy, by adjusting assembly components to and compensating for changes in terrain elevation. | 12-18-2008 |
20080308021 | PRECISION HOE OPENER WITH SWING LINK AND BIASING MEMBER - A precision hoe opener assembly is provided with improved accuracy of seeding as well as improved control over the opener and packer wheel assemblies. The opener assembly includes a hydraulically-driven parallel linkage assembly, a lost motion linkage, a biasing member, a ground engaging tool, and a packer wheel. The design provides improved seeding accuracy, by compensating for changes in draft force caused by changes in terrain elevation. | 12-18-2008 |
20080308022 | PRECISION HOE OPENER ASSEMBLY WITH ADJUSTABLE PACKER WHEEL LOCATION - A precision hoe opener assembly is provided with improved accuracy of seeding as well as improved control over the opener and packer wheel assemblies. The opener assembly features a hydraulically-driven parallel linkage assembly, a ground engaging tool, and an adjustable packer wheel assembly. The design provides improved seeding accuracy by providing a variable distance between the ground engaging tool and the packer wheel. Specifically, embodiments of the present invention allow for adjustment of the distance between the ground engaging tool and wheel elements. | 12-18-2008 |
20080308023 | PRECISION HOE OPENER WITH DRAFT FORCE COMPENSATION - A precision hoe opener assembly is provided with improved accuracy of seeding as well as improved control over the opener and packer wheel assemblies. The opener assembly includes a hydraulically-driven parallel linkage assembly, a swing link, a ground engaging tool, and a packer wheel. The design provides improved seeding accuracy, by compensating for changes in draft force caused by changes in terrain elevation. The swing link allows the cylinder to compensate for the forces applied to the ground engaging tool, thereby providing a substantially constant packing force to the soil beneath the packing wheel. | 12-18-2008 |
