1. An agricultural system comprising:
- a support structure;
a ground engaging assembly extending from the support structure;
a lost motion linkage cooperatively contacting the support structure to raise the ground engaging assembly after movement of the lost motion linkage through a desired angular range, wherein the lost motion linkage does not move the ground engaging assembly while the lost motion linkage moves through the desired angular range; and
a biasing member coupled to the ground engaging assembly and to the lost motion linkage for urging raising of the ground engaging assembly before the lost motion linkage moves through the desired angular range.

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.
