14. A work machine steering system, comprising:
a cylinder assembly configured to execute a steering command on the work machine;
a steering wheel assembly having a steering wheel;
a first sensor configured to identify movement of the steering wheel;
a joystick configured to selectively control the cylinder assembly;
a controller in communication with the first sensor and the joystick;
a frame having a front portion and a rear portion that pivot relative to one another;
the cylinder assembly coupled to the frame and configured to pivot the front portion relative to the rear portion;
an orbital valve assembly fluidly coupled to the cylinder assembly;
a first hydraulic pressure sensor configured to monitor a fluid pressure of the orbital valve assembly; and
an electro-hydraulic assembly having the joystick, the electro-hydraulic assembly being selectively fluidly coupled to the cylinder assembly;
the controller in communication with the first hydraulic pressure sensor and the joystick;
wherein, when the controller identifies an input with the first sensor and before the steering command is substantially executed, the controller disregards inputs from the joystick and steers the work machine based on inputs from the steering wheel assembly,
wherein, when the controller identifies a hydraulic pressure with the first hydraulic pressure sensor that is greater than a pressure threshold value, the controller prevents inputs from the joystick from manipulating the cylinder assembly.
