Abstract

An implement to remove levees and the like from the earth's surface includes a frame means with longitudinal and lateral members connected to form a frame having sides, a front and a rear end. A pair of ganged disc harrows is supported on the frame and depends therefrom. Each of said pair of said ganged disc harrows extends inwardly from a side of the frame and towards the rear end of the frame to form a generally V-shape with the apex of the V-shape being disposed adjacent the center longitudinal axis of the frame. Dozer blade means comprised of a pair of dozer blades. Each of the dozer blades extend from a side of the frame and inwardly towards the front end of the frame to form a generally V-shape with the apex of the V formed by the dozer blades being disposed adjacent but rearwardly of the apex of the V formed by the ganged disc harrows. The dozer blades cooperate with the ganged disc harrows to level the earth as the implement is moved thereover. Adjustable wheel means support the frame means and means are mounted on the frame means to adjust the wheels to a desired elevation and to maintain such wheels in such desired elevation to thereby regulate the distance between the earth and the frame and to thus regulate the depth of cut as the implement moves over the terrain.

Dependent claims

An implement for levelling levees and the like to the general contour of the earth's terrain comprising:

a. frame means;
b. said frame means including:
1. longitudinally extending, spaced members;
2. spaced lateral members extending between and connected to said longitudinally extending members to form a frame having spaced sides, a front and rear end;
3. tow bar means projecting from said front end of said frame;
and
c. a pair of ganged disc harrows supported by said frame means and depending downwardly therefrom;
d. each of said pair of ganged disc harrows extending inwardly from a side of said frame and towards the rear end of the frame to form a generally V shape with the apex of the V shape being disposed adjacent the center longitudinal axis of said frame;
e. dozer blade means supported by said frame means and depending therefrom;
f. said dozer blade means comprising a pair of dozer blades each of which extends from a side of said frame and inwardly towards the front end of the frame to form generally a V shape with the apex of the V being disposed adjacent but rearwardly of the apex of the V formed by said ganged disc harrows;
g. adjustable wheels means supporting said frame;
h. means to adjust said wheel means to raise and lower said frame relative to the terrain to thereby regulate the contact of said ganged disc harrows and dozer blade means with the earth;
and
i. said dozer blades each including an end portion which is pivotally mounted thereon whereby such end portion may be moved up on top of the balance of said dozer blade to reduce the width of the dozer blade.
