A management control device controls multiple unmanned vehicles, including the overtaking of a vehicle using an opposite lane. First and second travel permission sections are set for an own vehicle and another vehicle in a stopped state located ahead of the own vehicle on a traveling lane. A path by which the own vehicle overtakes the other vehicle is generated to include a first transition section to change lanes from a traveling lane to an opposite lane, an overtaking section that connects to the first transition section. Also included is a second transition section that connects to the front end of the overtaking section and is for the own vehicle to return to the traveling lane. The section length of the second travel permission section being set in advance is thereby shortened. |

An agricultural undercut implement includes a frame carrying ground-engaging rolling means, a cutting disk arrangement to cut parallel slits in the ground soil, and an undercut assembly having upright cutting edges each aligned to follow a slit, and a transverse blade with a horizontal cutting edge disposed to undercut the ground soil between slits, as the frame rolls over the ground, such as when towed behind a tractor. The transverse blade is configured to sever the strip of ground soil undercut by the cutting edge, and then move the undercut soil strip up and over the blade before replacing it intact on the ground. A method of agricultural crop management includes non-terminatingly retarding the growth of a permanent cover crop by using the implement to undercut and replace intact the ground soil beneath the cover crop. Some examples include drive units configured to drive blades through pluralities of blade positions. |
