Outdoor power equipment unit having encapsulated, housing free electronic controller

This invention relates to an outdoor power equipment unit, such as a mower, having an electronic controller comprising a circuit board with a plurality of connector pins affixed thereto and with a connector housing surrounding the pins. A Macromelt overmold encapsulates the circuit board and is bonded to the connector housing to form a controller that needs no external housing and no separate wire harness extending from the connector pins to the circuit board. The controller can log the length of time of various operations of the unit as well as the number of various occurrences. In addition, the controller can prevent overheating by automatically disabling operation of the working implement carried by the unit but permitting continued operation of the prime mover when overheating of the prime mover is detected.
