    Abstract: An outdoor unit has a frame that carries a ground grooming or working implement, a traction drive, and a cooling fan, all of which comprises loads on a prime mover. A power management controller automatically reduces an operational speed of the traction drive when prime mover droop is present. The cooling fan cools two cooling fluids. The controller stores data representing variable fan speeds for cooling each cooling fluid in both normal and above normal temperature ranges and for use when prime mover droop is present. The controller uses the highest fan speed required for cooling the cooling fluids in the normal range unless the droop fan speed is lower in which case the lower droop fan speed is used but only to the extent that the lower droop fan speed is not lower than the highest fan speed required for cooling the cooling fluids in the above normal temperature range.

    Abstract: A method for operating an autonomous machine involves determining one or more windows of availability over a time period when the autonomous machine is allowed to operate to perform one or more operational tasks. An operating schedule is determined for a work region that assigns the one or more operational tasks to the one or more windows of availability based a total operation time. At least one operational task is prioritized to cover an isolated containment zone before at least one other operational task to cover an autonomous containment zone in the operating schedule.
