Abstract:
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.
