1. A method for operating a mower, the method comprising defining a reference axis of rotation at a desired point along a path segment of the mower;
- orienting the wheels generally tangentially to a circular region about the reference axis of rotation; and
applying rotational mechanical energy to one or more of the wheels to rotate the mower by a desired angular amount about the reference axis.

Abstract
A method for operating a mower comprises defining a reference axis of rotation at a desired point along a path segment of the mower. A controller orients wheels of the mower generally tangentially to a circular region about the reference axis. A drive motor applies rotational mechanical energy to one or more of the wheels to rotate the mower by a desired angular amount about the reference axis.

10. A method of executing a path plan, the method comprising:
-
moving along a first row of a path plan in a first direction. defining an end point of the first row as a first axis of rotation;
rotating the mower by approximately ninety degrees with respect to the first axis of rotation;
moving along a transverse section that is substantially orthogonal to the first row;
defining an end point of the transverse section as a second axis of rotation;
rotating the mower by approximately ninety degrees with respect to the second axis of rotation; and
moving the mower along a second generally linear row in a generally opposite direction with respect to the first direction. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method of executing a path plan, the method comprising:
-
moving along a first row of a path plan in a first direction;
defining an end point of the first row;
rotating a steered direction of wheels of the mower with respect to a steered axis by approximately ninety degrees when the mower is at or near the end point;
moving along a transverse section that is substantially orthogonal to the first row;
defining an end point of the transverse section;
rotating a steered direction of wheels of the mower by approximately ninety degrees when the mower is at or near the end point; and
moving the mower along a second generally linear row in a generally opposite direction with respect to the first direction.
