Abstract

Adapter ( 27 ) of an agricultural implement, having a first, cylindrically contoured section ( 27 a ), the external diameter of which is designed to couple the agricultural implement to a US quick-hitch attachment system of an agricultural support vehicle, and having a second, spherically contoured section ( 27 b ), the external diameter of which is designed to couple the agricultural implement to a European lower-link attachment system of an agricultural support vehicle.

First claim

The invention claimed is:

1. An adapter ( 27 ) of an agricultural implement comprising:
a first cylindrically contoured section ( 27 a ), an external diameter of which is designed to couple the agricultural implement to a US quick-hitch attachment system of an agricultural support vehicle; and
a second spherically contoured section ( 27 b ), an external diameter of which is designed to couple the agricultural implement to a European lower-link attachment system of an agricultural support vehicle, wherein the first cylindrically contoured section ( 27 a ) and the second cylindrically contoured section ( 27 b ) are a one-piece adapter bush which has a recess ( 29 ) into which a carrier pin ( 30 ) can be pushed.

2. The adapter according to claim 1 , characterized in that the two sections ( 27 a , 27 b ) are arranged beside each other.

3. The adapter according to claim 1 , characterized in that a first run-on disk ( 27 c ) with a run-on bevel ( 27 d ) facing the cylindrically contoured section ( 27 a ) is formed on a first side of the cylindrically contoured section ( 27 a ), and in that a second run-on disk ( 27 e ) having a run-on bevel ( 27 f ) facing the cylindrically contoured section ( 27 a ) is formed on a second side of the cylindrically contoured section ( 27 a ).

4. The adapter according to claim 3 , characterized in that the second run-on disk ( 27 e ) also has a run-on bevel ( 27 g ) facing the spherically contoured section ( 27 b ).

5. The adapter according to claim 3 , characterized in that the run-on disks ( 27 c , 27 e ) have a width between 2 mm and 6 mm.

6. The adapter according to claim 5 , wherein the run-on disks ( 27 c , 27 e ) have a width between 3 mm and 5 mm.

7. The adapter according to claim 1 , characterized in that the cylindrically contoured section ( 27 a ) has a length which corresponds to the width of the US quick-hitch attachment system, which includes the length of a US quick-hitch attachment system of Category 2 or Category 3N or Category 3.

8. The adapter according to claim 1 , characterized in that the spherically contoured section ( 27 b ) has a diameter which corresponds to the diameter of the European lower-link attachment system, which includes the diameter of a European lower-link attachment system of Category II or Category III.

9. An agricultural implement comprising:
holders ( 26 , 26 ′); and
adapters ( 27 ) according claim 1 , which are mounted on the holders ( 26 , 26 ′).

10. The agricultural implement according to claim 9 , characterized in that each of the holders ( 26 , 26 ′) have two lugs ( 31 ) spaced apart from each other on which a respective adapter ( 27 ) is mounted.

11. The agricultural implement according to claim 10 , characterized in that a carrier pin ( 30 ) extends through the lugs ( 31 ) of each of the holders ( 26 , 26 ′).

12. The agricultural implement according to claim 10 , characterized in that
a spacing (X) between the lugs ( 31 ) closest to one another on opposing holders ( 26 , 26 ′) corresponds at most to an internal dimension of a hook spacing of the US quick-hitch attachment system of Category 2 or 3N,
a spacing (Y) between the lugs ( 31 ) farthest away from each other on opposing holders ( 26 , 26 ′) corresponds at least to an external dimension of the hook spacing of the US quick-hitch attachment system of Category 3.

13. The agricultural implement according to claim 10 , characterized in that the lugs have insertion bevels ( 34 ).

14. The agricultural implement according to claim 10 , characterized in that the agricultural implement is a mowing machine or a swather or a merger or a tedder.
