Abstract

A three point connection dolly for connecting an articulating tractor to a plow includes a dolly having a three point plow hitch configured to connect to a plow. The dolly also includes a chassis frame with a tractor hitch extension configured to extend the three point plow hitch a distance from the articulating tractor sufficient to allow rear wheels of the articulating tractor to fully turn.

Claims (34)

1. A dolly, comprising:

a chassis frame;

a three point plow hitch mounted on the chassis frame and configured to connect to a plow; and

a tractor hitch extension extending from the chassis frame by at least a predetermined distance and configured for connection with an articulating tractor,

wherein the predetermined distance is sufficient to space the chassis frame from rear wheels of the articulating tractor when the dolly is connected to the articulating tractor, and

where a width of tractor hitch extension is sufficiently narrow so as to not interfere with full turning of the rear wheels on the articulating tractor when the dolly is connected to the articulating tractor.

2. The dolly of claim 1 , wherein the chassis frame further comprises a three connection point frame and a hitch extension.

3. The dolly of claim 2 , wherein the three connection point frame is configured to connect and secure an alignment assembly.

4. The dolly of claim 2 , wherein the hitch extension extends the three point plow hitch from a hitch connector a distance to provide clearance from the plow.

5. The dolly of claim 4 , where the distance between the three point plow hitch from the hitch connector is 2-3 feet.

6. The dolly of claim 1 , further comprising:

an alignment assembly connecting the three point plow hitch to the chassis frame and configured to align connections of the three point plow hitch with the plow.

7. The dolly of claim 6 , wherein the alignment assembly comprises a first arm, a second arm, and a third arm, each individually connecting from a three point plow frame to the three point plow hitch.

8. The dolly of claim 7 , wherein the first arm and the second arm are configured to lift the three point plow hitch.

9. The dolly of claim 8 , wherein the first arm and the second arm each includes an actuator configured to extend in a manner to lift the three point plow hitch.

10. The dolly of claim 7 , wherein the third arm is configured to align the three point plow hitch.

11. A tractor assembly, comprising

an articulating tractor configured to pull a plow; and

a dolly connected to the articulating tractor, the dolly comprising:

a chassis frame,

a three point plow hitch mounted on the chassis frame and configured to connect to a plow, and

a tractor hitch extension extending from the chassis frame by at least a predetermined distance and configured for connection with an articulating tractor,

wherein the predetermined distance is sufficient to space the chassis frame from rear wheels of the articulating tractor, and

wherein a width of tractor hitch extension is sufficiently narrow so as to not interfere with full turning of the rear wheels on the articulating tractor.

12. The dolly of claim 11 , wherein the chassis further comprises a three connection point frame and a hitch extension.

13. The dolly of claim 12 , wherein the three connection point frame is configured to connect and secure an alignment assembly.

14. The dolly of claim 12 , wherein the hitch extension extends the three point plow hitch from a hitch connector a distance to provide clearance from the plow.

15. The dolly of claim 14 , where the distance between the three point plow hitch from the hitch connector is 2-3 feet.

16. The dolly of claim 11 , further comprising:

an alignment assembly connecting the three point plow hitch to the chassis and configured to align connections of the three point plow hitch with the plow.

17. The dolly of claim 16 , wherein the alignment assembly comprises a first arm, a second arm, and a third arm, each individually connecting from a three point plow frame to the three point plow hitch.

18. The dolly of claim 17 , wherein the first arm and the second arm are configured to lift the three point plow hitch.

19. The dolly of claim 18 , wherein the first arm and the second arm each includes an actuator configured to extend in a manner to lift the three point plow hitch.

20. The dolly of claim 17 , wherein the third arm is configured to align the three point plow hitch.
