A ride control system for a power machine having a lift arm movably coupled to a frame. A hydraulic cylinder configured to selectively control movement of the lift arm relative to the frame. An accumulator is in selective communication with a first end of the hydraulic cylinder. A pressure sensor communicates a signal indicative of a hydraulic pressure at a first end of the hydraulic cylinder. A ride control circuit allows selective communication between the accumulator and the first end of the hydraulic cylinder. A controller receives the signal from the pressure sensor, and prevents communication between the accumulator and the first end of the hydraulic cylinder until the signal from the pressure sensor indicates a pressure below an initial pressure threshold value.
