Abstract
A mower including a housing having a cutting apparatus such as a flail mower rotatably mounted therein. The mower includes a detector which determines during mower raising when the housing is positioned at least a predetermined distance above the ground surface directly below the housing. After passage of a time period during which the detector continuously detects that the housing is positioned at least the predetermined distance from the ground, a signal is sent to an actuator mechanism which interrupts the delivery of power to the motor rotating the cutting apparatus such that the flail mower comes to a stop. In one embodiment, a locking mechanism can be provided which prevents power from being reintroduced to the mower motor after the mower is lowered until the operator purposefully disengages the locking mechanism.
