Abstract
A compact utility loader incorporating a boom of adjustable length. The boom may include one or more lift arm assemblies, with each lift arm assembly including a first lift arm that telescopically receives a second lift arm. Each lift arm assembly also includes a telescoping actuator adapted to telescopically extend and retract its second lift arm relative to its first lift arm. A load-sensing system may be provided and adapted to limit lift arm assembly extension based at least in part upon a tool load applied at a tool supported by the boom.
