1. A skid-steer loader system, comprising:
a skid-steer loader comprising a frame;
an attachment assembly configured to couple to the skid-steer loader;
a hydraulic system, comprising:
a first hydraulic cylinder configured to drive rotation of the attachment assembly relative to the frame of the skid-steer loader in a first rotational direction;
a valve assembly configured to adjust a flow of fluid to the first hydraulic cylinder, wherein the valve assembly comprises a first control valve and a second control valve; and
a controller configured to receive an operator input from an input device and to control the valve assembly to a first configuration to provide the flow of fluid to the first hydraulic cylinder to drive the rotation of the attachment assembly relative to the frame of the skid-steer loader in the first rotational direction based on the operator input;
wherein the controller is configured to receive an additional input indicative of whether the attachment assembly is coupled to the skid-steer loader, to control the first control valve to enable the flow of fluid to the second control valve in response to the additional input indicating that the attachment assembly is coupled to the skid-steer loader, and to control the second control valve to provide the flow of fluid to the first hydraulic cylinder based on the operator input.
