Work machine with supplemental power steering

A method of steering a work machine having a hydrostatic transmission, the method comprising:

• selectively directing pressurized fluid from a primary source to a steering control valve;
• selectively directing pressurized fluid from the hydrostatic transmission to the steering control valve;
• and
• selectively actuating the steering control valve to communicate the pressurized fluid from at least one of the primary source and the hydrostatic transmission with a hydraulic actuator.

A work machine, comprising:

• at least one driven traction device;
• a hydrostatic transmission configured to drive the driven traction device;
• and
• a steering system configured to affect steering of the work machine, the steering system including:
• a primary source of pressurized fluid;
• a steering control valve;
• a first fluid passageway fluidly connecting the primary source of pressurized fluid to the steering control valve;
• and
• a second fluid passageway fluidly connecting the hydrostatic transmission to the steering control valve.
