Hoe-opener assembly

摘要

A hoe-opener assembly having a "float" feature is disclosed. The present invention ties operation of several hoe openers to a common framework so that uniform depth control can be maintained. The hoe-opener assembly of the present invention is drawn behind an agricultural implement having a tool bar, and comprises a vertically movable framework. A frame lift-and-lower arrangement is provided for adjusting the spacing of the framework relative to the ground. The hoe-opener assembly includes a plurality of spring-biased hoe openers, each pivotally carried for limited pivotal movement by the framework at spaced intervals along the length thereof. A biasing-spring arrangement in operative association with each hoe-opener is provided whereby each hoe opener is substantially fixed against independent movement, relative to the framework.
