Abstract: A method of controlling a lift arm actuator and a tilt actuator to control positioning of an implement carrier coupled to a lift arm of a power machine. An activation signal is received from an enabling input device. A lift arm control signal is received from a lift arm control input commanding movement of the lift arm. The lift arm actuator is controlled responsive to receipt of both of the activation signal and the lift arm control signal to move the lift arm to a target lift arm position and to move the implement carrier to or maintain the implement carrier at a target implement carrier orientation relative to a gravitational direction.

Abstract: 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.

Abstract: A power machine diagnostic system. The diagnostic tool system includes a first interface removably coupled to a power machine, a computer to identify a type of the power machine coupled at the first interface, and a second interface between the tool and the computer.
