Abstract

A grass management system includes a prohibition determination circuit and a baler. The prohibition determination circuit is configured to determine a prohibition position. The baler is configured to acquire the prohibition position from the prohibition determination circuit, and eject a bale of grass at a position except for the prohibition position.

First claim

What is claimed is:

1 . A grass management system comprising:
a prohibition determination circuit configured to determine a prohibition position; and a baler configured to
acquire the prohibition position from the prohibition determination circuit, and
eject a bale of grass at a position except for the prohibition position.

2 . The grass management system according to claim 1 , further comprising:
a display to display a farm field, wherein the prohibition determination circuit is configured to determine a range selected in the farm field on the display as the prohibition position.

3 . The grass management system according to claim 1 , wherein the prohibition determination circuit is configured to determine the prohibition position based on information at a time of traveling of a work machine to perform work of the grass.

4 . The grass management system according to claim 3 , further comprising:
a position detection circuit configured to detect a machine position at the time of traveling of the work machine to perform the work of the grass; and an operation circuit provided in the work machine, wherein the prohibition determination circuit is configured to determine the machine position when the operation circuit accept an operation as the prohibition position.

5 . The grass management system according to claim 3 , further comprising:
a position detection circuit configured to detect a machine position at the time of traveling of the work machine to perform the work of the grass; and an inclination detection circuit provided in the work machine and configured to detect an inclination at the time of traveling of the work machine, wherein the prohibition determination circuit is configured to determine, as the prohibition position, the machine position at which the inclination detected by the inclination detection circuit is equal to or greater than a threshold.

6 . The grass management system according to claim 1 , further comprising:
a topographical information detection circuit configured to detect topographical information on topography of a farm field; and a map creation circuit configured to create an inclination map of the farm field based on the topographical information, wherein the prohibition determination circuit is configured to determine, as the prohibition position, a position of the farm field at which an inclination angle indicated in the inclination map is equal to or greater than a threshold.

7 . The grass management system according to claim 6 , further comprising:
a display, wherein the display displays the inclination map.

8 . The grass management system according to claim 1 , further comprising:
a topographical information detection circuit configured to acquire the topographical information on the topography of a farm field, wherein the prohibition determination circuit is configured to determine the prohibition position based on a distance from a boundary of the farm field obtained from the topographical information.

9 . The grass management system according to claim 1 , further comprising:
a control circuit provided in the baler and configured to control an ejecting implement of the baler not to eject the bale when the baler is at the prohibition position.

10 . The grass management system according to claim 1 , further comprising:
a notification circuit provided in the baler and configured to notify that the baler is at the prohibition position when the baler is at the prohibition position.

11 . The grass management system according to claim 3 , wherein the work machine is the baler configured to bale the grass and eject the bale.

12 . The grass management system according to claim 3 , wherein the work machine is one of a harvesting machine configured to harvest the grass, a dispersion machine configured to disperse the grass, a grass raking machine configured to rake the grass, and a fertilizing machine configured to perform fertilization.

13 . A grass management system comprising:
prohibition determination means for determining a prohibition position; acquisition means for acquiring the prohibition position; and ejection means for ejecting a bale of grass at a position except for the prohibition position.

14 . A grass management method comprising:
determining a prohibition position, by a prohibition determination circuit; acquiring the prohibition position, by a baler; and ejecting a bale of grass at a position except for the prohibition position, by the baler.
