ABSTRACT:
The secondary steering system comprises a structure to prevent the reverse flow of fluid in the fluid bypass path around the fluid meter and provide a supply line from the reservoir to the pressurized fluid line. The supply line supplies hydraulic fluid to the fluid meter of the controller when hydraulic pressure has been lost. The fluid meter can then be manually driven by the operator to supply pressurized hydraulic fluid to the steering cylinders.
