Cold start lubricant distribution systems and work vehicles including the same

A cold start lubricant distribution system for usage onboard a work vehicle, the cold start lubricant distribution system comprising:

• a lubricant distribution circuit having a flow divider section;
• first and second actively-lubricated work vehicle assemblies fluidly interconnected by the lubricant distribution circuit;
• a lubricant supply pump located in the lubricant distribution circuit and, when active, urging lubricant flow through the flow divider section of the lubricant distribution circuit;
• and
• a lubricant flow modification assembly, comprising:
• shutoff valve movable between an open position and a closed position, the shutoff valve blocking lubricant flow to the first actively-lubricated work vehicle assembly when the shutoff valve is in the closed position;
• a valve actuator controllable to move the shutoff valve from the open position to the closed position;
• and
• a controller coupled to the valve actuator and configured to:
• (i) determine when to place the lubricant flow modification assembly in a cold start mode, and (ii) command the valve actuator to move the shutoff valve into the closed position when placing the lubricant flow modification assembly in the cold start mode.

A work vehicle, comprising:

• an actively-lubricated front axle assembly;
• an actively-lubricated rear axle assembly;
• and
• a cold start lubricant distribution system, comprising:
• a lubricant distribution circuit fluidly interconnecting the actively-lubricated front and rear axle assemblies;
• a flow divider section included in the lubricant distribution circuit and through which lubricant flow is apportioned between the actively-lubricated front and rear axle assemblies;
• a lubricant supply pump located in the lubricant distribution circuit upstream of the flow divider section;
• and
• a lubricant flow modification assembly operable in a cold start mode in which the lubricant flow modification assembly reduces a volume lubricant flow supplied to the actively-lubricated front axle assembly through the flow divider section relative to a volume of lubricant flow supplied to the actively-lubricated rear axle assembly through the flow divider section.
