Work vehicle drive with solenoid boosted lubrication pump

A work vehicle, comprising:

• a chassis;
• and
• a drive arrangement mounted to the chassis and including:
• a housing coupled to the chassis;
• an electric machine at least partially housed within the housing, configured to generate rotational power, and comprising an interface coupling at an electric machine output;
• a transmission at least partially housed within the housing, rotationally coupled to the interface coupling, and configured to transfer at least a portion of the rotational power from the electric machine to a drive output;
• a pump having a diaphragm and at least partially housed within the housing and configured to facilitate circulation of lubrication fluid about the transmission, wherein the pump is selectively driven, in a first mode of operation, by the rotational power of the electric machine;
• and
• a solenoid device at least partially housed within the housing and configured to selectively drive the pump in a second mode of operation.
