Abstract

A mower-conditioner machine which includes a frame, a cutter bar connected to the frame, the cutter bar is configured to cut a crop material from a field, and a crop-engaging member connected to the frame. The crop-engaging member is configured to contact the crop material. The mower-conditioner machine also includes at least one moisture sensor connected to the crop-engaging member. The at least one moisture sensor is configured to sense a moisture content of the crop material.

First claim

The invention claimed is:

1. A mower-conditioner machine, comprising:
a frame;
a cutter bar connected to the frame, the cutter bar being configured to cut a crop material from a field;
a crop-engaging member comprising a swathgate that is pivotally connected to the frame, the crop-engaging member being configured to contact the crop material; and
at least one moisture sensor adjacent an underside of the swathgate, the at least one moisture sensor being configured to sense a moisture content of the crop material.

2. The mower-conditioner machine of claim 1 , further comprising a controller operably connected to the at least one moisture sensor.

3. The mower-conditioner machine of claim 2 , wherein the controller is configured to receive location data regarding a location of the mower-conditioner machine in the field, wherein the controller is configured to generate a moisture content map based at least partially on the moisture content of the crop material and the location data.

4. The mower-conditioner machine of claim 3 , wherein the controller is configured to estimate a drying time of the crop material based at least partially on the moisture content map sectionalized by at least one of specific passes or zones of similarly grouped crop material.

5. The mower-conditioner machine of claim 1 , wherein the at least one moisture sensor is integrated into the swathgate.

6. The mower-conditioner machine of claim 1 , wherein the at least one moisture sensor is flush with the underside of the swathgate.

7. The mower-conditioner machine of claim 1 , further comprising a conditioning roll which is connected to the frame and configured to condition the crop material and at least one other moisture sensor coupled to the conditioning roll.

8. The mower-conditioner machine of claim 1 , wherein the at least one moisture sensor comprises one of a single electrode configured to sense a voltage drop between itself and a ground, a pair of electrodes configured to sense a voltage drop between themselves, and a wave-ranging sensor.

9. The mower-conditioner machine of claim 1 , further comprising a mount connecting the at least one moisture sensor to the crop-engaging member.

10. The mower-conditioner machine of claim 9 , wherein the mount is electrically insulated.

11. An agricultural assembly, comprising:
a work vehicle; and
a mower-conditioner machine, comprising:
a frame connected to work vehicle;
a cutter bar connected to the frame, the cutter bar being configured to cut a crop material from a field;
a crop-engaging member comprising a swathgate that is pivotally connected to the frame, the crop-engaging member being configured to contact the crop material; and
at least one moisture sensor adjacent an underside of the swathgate, the at least one moisture sensor being configured to sense a moisture content of the crop material.

12. The agricultural assembly of claim 11 , further comprising a controller operably connected to the at least one moisture sensor.

13. The agricultural assembly of claim 12 , further comprising a location sensor configured to sense and provide location data regarding a location of the mower-conditioner machine in the field, wherein the controller is configured to receive the location data and generate a moisture content map based at least partially on the moisture content of the crop material and the location data.

14. The agricultural assembly of claim 13 , wherein the controller is configured to estimate a drying time of the crop material based at least partially on the moisture content map sectionalized by at least one of specific passes or zones of similarly grouped crop material.

15. The agricultural assembly of claim 11 , wherein the at least one moisture sensor is integrated into the swathgate.

16. The agricultural assembly of claim 11 , wherein the at least one moisture sensor is flush with the underside of the swathgate.

17. The agricultural assembly of claim 11 , further comprising a conditioning roll which is connected to the frame and configured to condition the crop material and at least one other moisture sensor coupled to the conditioning roll.

18. The agricultural assembly of claim 11 , wherein the mower-conditioner machine further comprises a mount connecting the at least one moisture sensor to the crop-engaging member.

19. The agricultural assembly of claim 17 , wherein the mount is electrically insulated.

20. A method for conducting an agricultural procedure, comprising:
mowing a crop material in a field by a mower-conditioner machine having a frame and a crop-engaging member comprising a swathgate that is pivotally connected to the frame;
sensing, by at least one moisture sensor adjacent an underside of the swathgate, a moisture content of the crop material;
sensing, by a location sensor, a location of the mower-conditioner machine;
generating, by a controller, a moisture content map based at least partially on the moisture content of the crop material and the location of the mower-conditioner machine; and
estimating, by the controller, a drying time of the crop material based at least partially on the moisture content map.
