摘要 |
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.
