A method of allocating hydraulic fluid between two or more actuators in a machine processes a first command intended to provide a first requested fluid flow to a steering actuator for steering the machine, and a second command intended to provide a second requested fluid flow to a non-steeling actuator, such as a lift or tilt actuator. The system modifies the first and second commands to produce modified first and second commands corresponding to modified first and second fluid flows, such that the sum of the adjusted first and second fluid flows is less than or equal to a currently available flow and the modified first fluid flow meets or exceeds the lesser of the first requested fluid flow and a threshold curve that is a function of a machine variable such as engine speed or other variable or parameter.
