Abstract: A cultivator has soil working blade members mounted on a horizontal shaft which is driven to rotate the members forwardly through the soil in the normal direction of travel. A baffle comprised of screen segments are mounted on the cultivator frame to partially surround the blade members. The screen segments are biased about respective pivots and a rod grating is connected to the baffle to extend downardly immediately to the rear of the blade members. The rear screen segment has V-shaped guides to ridge the soil. A hopper communicates with dosing outlets, each outlet being a nozzle device that extends between a pair of guides. Each nozzle device is pivotable to either one of two positions for planting tubers deep or shallow. A pair of rear wheels is connected to the rear of the frame and the wheels are drivenly connected to dosing conveyors leading to the outlets. An adjusting device is associated with each wheel to raise and lower the soil working blade members.
Abstract: A multi-row vineyard cultivator for cultivating a plurality of generally parallel rows of grape vines simultaneously having a wheeled framework adapted to travel over the rows with first and second outriggers mounted on the framework extending from the framework in a direction generally perpendicular to the line of travel so that they overlie a row on each side of the framework. A downwardly depending post is provided on each of the outriggers. Cultivator assemblies are mounted on each of the posts which are adequate for one row. A hydraulic actuator is provided for moving the post and the cultivator assemblies carried thereby longitudinally along the outrigger associated therewith.
