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 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.
