Land plane

Abstract

A land plane to smooth and level any irregularities in the surface of an agricultural field. The land plane includes a main frame; a first wing frame attached to the first side of the main frame adjacent the front end thereof, a second wing frame attached to the second side of the main frame adjacent the rear end thereof; a V-shaped scrapper blade having an apex adjacent the front end of the main frame; a first transverse scrapper blade extending diagonally from the first wing frame across the main frame to the second wing frame and having a gap adjacent the second side of the main frame; and a second transverse scrapper blade means extending diagonally from the first wing frame across the main frame to the second wing frame, parallel to and spaced rearwardly from the first transverse scrapper blade.

1 . A land plane comprising: 
 (a) a main frame including a front end, a rear end, a first side, and a second sides;    (b) a first wing frame attached to said first side of said main frame adjacent said front end of said main frame;    (c) a second wing frame attached to said second side of said main frame adjacent said rear end of said main frame;    (d) a V-shaped scrapper blade means having an apex and mounted beneath said main frame with said apex adjacent said front end of said main frame substantially centered between said first and second sides of said main frame;    (e) a first transverse scrapper blade means mounted beneath said main frame, said first wing frame, and said second wing frame; said first transverse scrapper blade means extending diagonally from said first wing frame across said main frame to said second wing frame; said first transverse scrapper blade means having a gap adjacent said second side of said main frame; and    (f) a second transverse scrapper blade means mounted beneath said main frame, said first wing frame, and said second wing frame; said second transverse scrapper blade means being parallel to and spaced rearwardly from said first transverse scrapper blade means, and extending diagonally from said first wing frame across said main frame to said second wing frame.    
   
   
       2 . The land plane of  claim 1  in which said first transverse scrapper blade means includes a first scrapper blade mounted beneath said first wing frame, a main scrapper blade mounted beneath said main frame, and a second scrapper blade mounted beneath said second wing frame with said gap of said first transverse scrapper blade means formed between said main and second scrapper blades; and in which said second transverse scrapper blade means includes a first scrapper blade mounted beneath said first wing frame, a main scrapper blade mounted beneath said main frame, and a second scrapper blade mounted beneath said second wing frame.  
   
   
       3 . The land plane of  claim 2  in which said first wing frame is pivotally attached to said first side of said main frame for movement between a raised position and a deployed position; in which said second wing frame is pivotally attached to said second side of said main frame for movement between a raised position and a deployed position.  
   
   
       4 . A land plane for being pulled by a tow vehicle over a field to smooth and level any irregularities in the surface of the field; said land plane comprising: 
 (a) a main frame including a front end, a rear end, a first side, and a second side;    (b) a first wing frame pivotally attached to said first side of said main frame adjacent said front end of said main frame;    (c) hydraulic means for causing said first wing frame to pivot between a raised position and a deployed position;    (d) a second wing frame pivotally attached to said second side of said main frame adjacent said rear end of said main frame;    (e) hydraulic means for causing said second wing frame to pivot between a raised position and a deployed position;    (f) a V-shaped scrapper blade means having an apex and mounted to and beneath said main frame with said apex adjacent said front end of said main frame substantially centered between said first and second sides of said main frame;    (g) a first transverse scrapper blade means mounted to and beneath said main frame, said first wing frame, and said second wing frame; said first transverse scrapper blade means extending diagonally from said first wing frame across said main frame to said second wing frame; said first transverse scrapper blade means having a gap adjacent said second side of said main frame; said first transverse scrapper blade means includes a first scrapper blade mounted to and beneath said first wing frame, a main scrapper blade mounted to and beneath said main frame, and a second scrapper blade mounted to and beneath said second wing frame with said gap of said first transverse scrapper blade means formed between said main and second scrapper blades;    (h) a second transverse scrapper blade means mounted to and beneath said main frame, said first wing frame, and said second wing frame; said second transverse scrapper blade means being parallel to and spaced rearwardly from first transverse scrapper blade means, and extending diagonally from said first wing frame across said main frame to said second wing frame; said second transverse scrapper blade means including a first scrapper blade mounted to and beneath said first wing frame, a main scrapper blade mounted to and beneath said main frame, and a second scrapper blade mounted to and beneath aid second wing frame;    (i) a hitch attached to the top of said front end of said main frame for allowing said land plane to be hitched to the tow vehicle; and    (j) a hydraulic cylinder between said hitch said the top of said front end of said main frame.
