Cultivators
First Claim
1. A cultivator having a frame and soil working members rotatably mounted on said frame, driving means connected to said members to move same through the soil, baffle means being positioned adjacent said members and said baffle means including a screen and a pair of soil guide members with spaced apart lower edges positioned to the rear of the soil working members with respect to the normal direction of travel of the cultivator to receive worked soil from said soil working members, said pair of guide members extending upwardly and outwardly from said lower edges in substantially V-shaped relationship to one another in said edges being spaced apart to leave a gap through which worked soil received at the rear of rotatably soil working members is ridged.

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.

- 1. A cultivator having a frame and soil working members rotatably mounted on said frame, driving means connected to said members to move same through the soil, baffle means being positioned adjacent said members and said baffle means including a screen and a pair of soil guide members with spaced apart lower edges positioned to the rear of the soil working members with respect to the normal direction of travel of the cultivator to receive worked soil from said soil working members, said pair of guide members extending upwardly and outwardly from said lower edges in substantially V-shaped relationship to one another in said edges being spaced apart to leave a gap through which worked soil received at the rear of rotatably soil working members is ridged.
- 3. A cultivator having a frame supporting a hopper and soil working members rotatably mounted on said frame, driving means connected to said members to move same through the soil, a baffle comprising a screen being located adjacent and to the rear of said members with respect to the normal direction of travel and said screen including at least one pair of soil guide members that is positioned at the lower portion of said screen, said pair of guide members being positioned adjacent the soil during operation and extending upwardly and outwardly from the soil in substantially V-shaped relationship to one another, said guide members being spaced apart from one another to leave a gap that forms a ridge of worked soil received via said screen, dosing means communicating with said hopper and said dosing means including an outlet located between said guide members above said gap to introduce material in the worked soil.

15. A cultivator having a frame and soil working members rotatably mounted on said frame, driving means connected to said members to move same through the soil, a baffle being located adjacent said members and said baffle comprising a plurality of screens that are separately pivoted to said frame, a rear screen including at least one pair of spaced apart soil guide members, a grating of said baffle extending downwardly in front of said rear screen and to the rear of the soil working members with respect to the normal direction of travel, said soil working members being mounted on a substantially horizontal shaft, said driving means connected to rotate said soil working members to throw soil through said grating to said guide members, dosing means, including a nozzle-like device, extending between the guide members and above a gap formed between these members, said dosing means including conveyor means, further driving means connected to move said conveyor means and deliver material to soil being ridged by said guide members.
