    Abstract: Disclosed are power machines and lift arm suspension or ride control systems for use thereon. A lift arm assembly is pivotally coupled to a frame of the power machine and is capable of being raised and lowered. A selectively activated lift arm suspension system is operably coupled to the lift arm assembly. A controller is coupled to the suspension system and configured to determine whether the lift arm assembly has moved more than a threshold amount. The controller deactivates the lift arm suspension system in response to determining that the lift arm assembly has moved more than the threshold amount.
