Abstract

An agricultural header includes: a header frame; at least one cutter carried by the header frame and configured to cut crop material; and a transport assembly coupled to the header frame and including: a gauge wheel arm pivotably coupled to the header frame and pivotable between a transport position and a working position; and a dolly coupled to the gauge wheel arm and including a pair of dolly wheel mounts configured to mount a pair of wheels thereto. The dolly is coupled to the gauge wheel arm such that the dolly is carried by the gauge wheel arm between the transport position and the working position and is swivelable about a swivel axis extending through the gauge wheel arm when the gauge wheel arm is in the transport position.

First claim

What is claimed is:

1. An agricultural header for an agricultural vehicle, comprising:
a header frame;
at least one cutter carried by the header frame and configured to cut crop material; and
a transport assembly coupled to the header frame, the transport assembly comprising:
a gauge wheel arm that is pivotably coupled to the header frame and pivotable between a transport position and a working position; and
a dolly coupled to the gauge wheel arm and comprising a pair of dolly wheel mounts configured to mount a pair of wheels thereto, the dolly being coupled to the gauge wheel arm such that the dolly is carried by the gauge wheel arm between the transport position and the working position and is swivelable about a swivel axis extending through the gauge wheel arm when the gauge wheel arm is in the transport position,
wherein the gauge wheel arm comprises a body section comprising (i) a pair of arm wheel mounts configured to mount the pair of wheels thereto, (ii) a pair of mounting arms coupling the body section to the header frame, and (iii) a dolly opening defined between the pair of arm wheel mounts and the pair of mounting arms,
wherein the pair of arm wheel mounts comprises a first pair of openings formed in the gauge wheel arm, the first pair of openings extending along a first axis,
wherein the pair of mounting arms comprises a second pair of openings formed in the gauge wheel arm, the second pair of openings extending along a second axis,
wherein the dolly opening extends along a third axis that is coincident with the swivel axis and transverse to the first and second axes, and
wherein the third axis is disposed along the body section at a location between the first and second axes.

2. The agricultural header of claim 1 , wherein the dolly comprises a dolly post disposed in the dolly opening.

3. The agricultural header of claim 1 , wherein the dolly wheel mounts are aligned on a dolly wheel axis, the dolly wheel axis extending in a direction that is transverse to a direction in which the first axis extends.

4. The agricultural header of claim 3 , wherein the dolly wheel axis extends in a direction that is perpendicular to the direction in which the first axis extends when the gauge wheel arm is in the working position.

5. The agricultural header of claim 1 , further comprising an arm lock movably coupled to the header frame, the gauge wheel arm comprising a corresponding arm lock that is configured to couple with the arm lock when the gauge wheel arm is in the transport position to lock the gauge wheel arm in the transport position.

6. The agricultural header of claim 1 , further comprising a pair of wheels, each of the wheels being coupled to a respective one of the dolly wheel mounts.

7. The agricultural header of claim 1 , further comprising a cylinder coupled to the gauge wheel arm when the gauge wheel arm is in the working position.

8. An agricultural vehicle, comprising:
a chassis; and
a header carried by the chassis, the header comprising:
a header frame;
at least one cutter carried by the header frame and configured to cut crop material; and
a transport assembly coupled to the header frame, the transport assembly comprising:
a gauge wheel arm that is pivotably coupled to the header frame and pivotable between a transport position and a working position; and
a dolly coupled to the gauge wheel arm and comprising a pair of dolly wheel mounts configured to mount a pair of wheels thereto, the dolly being coupled to the gauge wheel arm such that the dolly is carried by the gauge wheel arm between the transport position and the working position and is swivelable about a swivel axis extending through the gauge wheel arm when the gauge wheel arm is in the transport position,

wherein the gauge wheel arm comprises a body section comprising (i) a pair of arm wheel mounts configured to mount the pair of wheels thereto, (ii) a pair of mounting arms coupling the body section to the header frame, and (iii) a dolly opening defined between the pair of arm wheel mounts and the pair of mounting arms,
wherein the pair of arm wheel mounts comprises a first pair of openings formed in the gauge wheel arm, the first pair of openings extending along a first axis,
wherein the pair of mounting arms comprises a second pair of openings formed in the gauge wheel arm, the second pair of openings extending along a second axis,
wherein the dolly opening extends along a third axis that is coincident with the swivel axis and transverse to the first and second axes, and
wherein the third axis is disposed along the body section at a location between the first and second axes.

9. The agricultural vehicle of claim 8 , wherein the dolly comprises a dolly post disposed in the dolly opening.

10. The agricultural vehicle of claim 8 , wherein the dolly wheel mounts are aligned on a dolly wheel axis, the dolly wheel axis extending in a direction that is transverse to a direction in which the first axis extends.

11. The agricultural vehicle of claim 10 , wherein the dolly wheel axis extends in a direction that is perpendicular to the direction in which first axis extends when the gauge wheel arm is in the working position.

12. The agricultural vehicle of claim 8 , further comprising an arm lock movably coupled to the header frame, the gauge wheel arm comprising a corresponding arm lock that is configured to couple with the arm lock when the gauge wheel arm is in the transport position to lock the gauge wheel arm in the transport position.

13. The agricultural vehicle of claim 8 , further comprising a pair of wheels, each of the wheels being coupled to a respective one of the dolly wheel mounts.

14. The agricultural vehicle of claim 8 , further comprising a cylinder coupled to the gauge wheel arm when the gauge wheel arm is in the working position.
