Abstract

A heavy gauge agricultural implement hitch is disclosed which is offset such that the implement and the tractor are not directly in line with one another, but allows the tractor to follow the previous crop rows and the implement to be offset of the previous crop rows. This offset of the hitch allows the implement to function with more ease, especially when the implement is a planter, thus making it possible to plant soybeans, for example, more easily in a field with corn stubble.

Claims (29)

1. In a combination of a towed agricultural implement having a horizontal centerline and a forwardly extending draft tongue, and a hitch for connecting the implement tongue to a vehicle for towing the implement in a direction of travel, the vehicle for towing having a longitudinal centerline, the improvement comprising:

a first rigid generally planar and vertical plate having length, height and thickness dimensions, said length and height dimensions generally perpendicular to the direction of travel, said first plate having a first side in the direction of travel and an opposing second side, said first and second sides sharing said length and height dimensions;

a first pair of rigid generally planar and vertical spaced-apart plates affixed to said first side of said first plate and extending generally perpendicularly therefrom in the direction of travel, each of said spaced-apart plates making up said first pair of plates has a plurality of vertically aligned holes therethrough for vertically adjustably attaching the hitch to the towing vehicle;

a second pair of rigid generally planar and vertical spaced-apart plates affixed to said second side of said first plate and extending generally perpendicularly therefrom in a direction opposite the direction of travel, each of said spaced-apart plates making up said second pair of plates has a plurality of vertically aligned holes therethrough for vertically adjustably attaching the hitch to the implement; and

said first pair of plates and said second pair of plates being offset one from the other along said length dimension of said first plate such that the centerline of the implement does not align with the longitudinal centerline of a towing vehicle, whereby the towing vehicle may follow previous crop rows with the implement being slightly offset of the previous crop rows.

2. The improvement of claim 1 , wherein:

said offset is approximately 7.5 inches.

3. The improvement of claim 2 , wherein:

said offset is approximately 7.5 inches, and the offset can be selectively changed from one side of the longitudinal centerline of the towing vehicle by flipping the hitch 180 degrees forwardly.

4. The improvement of claim 3 , wherein:

said agricultural implement is a planter.

5. A hitch for connecting an agricultural implement having a horizontal centerline and a forwardly extending draft tongue to a vehicle for towing the implement in a direction of travel, the towing vehicle having a longitudinal centerline, the hitch comprising;

a first rigid generally planar and vertical plate having length, height and thickness dimensions, said length and height dimensions a primary dimension generally perpendicular to the direction of travel, said first plate having a first side in the direction of travel and an opposing second side, said first and second sides sharing said length and height dimensions;

a first pair of rigid generally planar and vertical spaced-apart plates affixed to said first side of said first plate and extending generally perpendicularly therefrom in the direction of travel, each of said spaced-apart plates making up said first pair of plates has a plurality of vertically aligned holes therethrough for vertically adjustably attaching the hitch to the towing vehicle;

a second pair of rigid generally planar and vertical spaced-apart plates affixed to said second side of said first plate and extending generally perpendicularly therefrom in a direction opposite the direction of travel, each of said spaced-apart plates making up said second pair of plates has a plurality of vertically aligned holes therethrough for vertically adjustably attaching the hitch to the implement; and

said first pair of plates and said second pair of plates being offset one from the other along said length dimension of said first plate such that the centerline of the implement does not align with the longitudinal centerline of a towing vehicle, whereby the towing vehicle may follow previous crop rows with the implement being slightly offset of the previous crop rows.

6. The improvement of claim 5 , wherein:

said offset is approximately 7.5 inches.

7. The improvement of claim 6 , wherein:

the offset can be selectively changed from one side of the longitudinal centerline of the towing vehicle by flipping the hitch 180 degrees forwardly.

8. The improvement of claim 7 , wherein:

said agricultural implement is a planter.

9. A hitch for connecting a tractor to an agricultural planter and towing it in a direction of travel, the hitch comprising:

a first rigid generally planar and vertical plate having length, height and thickness dimensions, said length and height dimensions generally perpendicular to the direction of travel, said first plate having a first side in the direction of travel and an opposing second side, said first and second sides sharing said length and height dimensions;

a first pair of rigid generally planar and vertical spaced-apart plates affixed to said first side of said first plate and extending generally perpendicularly therefrom in the direction of travel, each of said spaced-apart plates making up said first pair of plates has a plurality of vertically aligned holes therethrough for vertically adjustably attaching the hitch to the towing vehicle;

a second pair of rigid generally planar and vertical spaced-apart plates affixed to said second side of said first plate and extending generally perpendicularly therefrom in a direction opposite the direction of travel, each of said spaced-apart plates making up said second pair of plates has a plurality of vertically aligned holes therethrough for vertically adjustably attaching the hitch to the implement; and

said first pair of plates and said second pair of plates being offset one from the other along said length dimension of said first plate whereby the tractor may follow previous crop rows with the implement being slightly offset of the previous crop rows.

10. The improvement of claim 9 , wherein:

said offset is approximately 7.5 inches, and the offset can be selectively changed from one side of the longitudinal centerline of the towing vehicle by flipping the hitch 180 degrees forwardly.
