Abstract: A utility loader incorporating a boom of adjustable length. The boom includes either or both of a left and right arm assembly, with each lift arm assembly including a rear lift arm telescopingly engaged with a front lift arm. Each lift arm assembly also includes an extension actuator adapted to variably extend and retract the front lift arm relative to the rear lift arm. The lift arm assembly includes a connection point to, e.g., receive a tool assembly, and the motion of the lift arm assembly is synchronized to move the connection point along a predetermined path. In one or more embodiments, the predetermined path includes moving along a direction that is normal to the ground surface.

Abstract: Embodiments of the present disclosure relate generally to underground horizontal directional drills and, more particularly, to aspects of drill operation, ground anchoring, and operator assistance features. In some embodiments, a drill is provided that includes an anchor assembly and/or a rear stabilizer that may pivot relative to a carriage frame of the drill. In other embodiments, a roller bearing system that permits the carriage to translate along the carriage frame is provided. In still other embodiments, rests to support the drill rod during makeup and breakout are described.
